Daniel Harlow awarded Packard Foundation Fellowship https://news.mit.edu/2020/daniel-harlow-packard-foundation-fellowship-1020 MIT News - Quantum computing urn:uuid:b9aa6dcd-63ae-40b6-abcc-470ad7fff863 Tue, 20 Oct 2020 16:01:00 +0000 Physics professor receives one of the most prestigious nongovernmental awards for early-career scientists. <p>The David and Lucile Packard Foundation has announced that <a href="http://web.mit.edu/physics/people/faculty/harlow_daniel.html">Daniel Harlow</a>, assistant professor of physics and a researcher at the <a href="http://www-ctp.mit.edu/">MIT Center for Theoretical Physics</a>, has been named a Packard Fellow for Science and Engineering. The Packard Foundation Fellowships are one of the most prestigious and well-funded non-governmental awards for early-career scientists.</p> <p>Each year, the foundation invites 50 university presidents to nominate two early-career professors each from their institutions; from those 100 nominees, an advisory panel of distinguished scientists and engineers select the fellows, who receive individual grants of $875,000 over five years. The 2020 class comprises 20 fellows.&nbsp;</p> <p>“Daniel Harlow has emerged as a leader in formal field theory and continues MIT’s great tradition in formal theory," says Peter Fisher, professor and head of MIT’s Department of Physics.</p> <p>Harlow researches black holes by combining quantum mechanics and Einstein's general relativity. The Packard Foundation recognized Harlow’s use of ideas from quantum computation to generate new insights about both black holes and quantum computers.</p> <p>“Understanding the quantum properties of black holes has been one of the great challenges in physics for the last five decades, and in recent years we have learned that it is closely related to many other interesting problems,” says Harlow.&nbsp;“In particular there is an ongoing interplay with the theories of condensed matter systems and quantum computers. It is my hope that with this fellowship my group and I will be able to make progress on all of these fronts, helping to create a new kind of physics where the old boundaries between subfields are forgotten and any interesting problem is fair game.”&nbsp;&nbsp;</p> <p>Harlow is a co-discoverer of a close connection between the anti-de Sitter/conformal field theory (AdS/CFT) correspondence, a relationship between certain theories of quantum gravity and quantum field theories, and the theory of quantum error correcting codes. With Kavli Institute for the Physics and Mathematics of the Universe and Caltech scientist Hirosi Ooguri, he also recently developed a new understanding of symmetry in particle physics and gravity, with which they were able to prove that no global symmetry can exist on the gravity side of the AdS/CFT correspondence.</p> <p>Harlow was a postdoc at Princeton and Harvard universities before joining MIT in July 2017. He earned a doctorate in physics from Stanford University in 2012, and received his bachelor’s degree in physics and mathematics from Columbia University in 2006.</p> <p>Harlow was awarded the&nbsp;<a href="https://breakthroughprize.org/Laureates/1/L3835">2019 New Horizons in Physics Prize</a>&nbsp;"for fundamental insights about quantum information, quantum field theory, and gravity,” and is a member of the Simons Foundation’s <a href="https://www.simonsfoundation.org/mathematics-physical-sciences/it-from-qubit/">"It from Qubit"</a> Collaboration on Quantum Fields, Gravity, and Information.</p> <p>“I am thrilled to be receiving a Packard Fellowship!” says Harlow. “It is a great honor to be entrusted with this responsibility, and I hope I will be able to live up to the high standards of my predecessors.”</p> <p>Past Packard fellows have gone on to receive such honors as the Nobel Prize in chemistry and physics, the Fields Medal, the Alan T. Waterman Award, MacArthur Fellowships, and elections to the National Academies.</p> Sandi Miller | Department of Physics Daniel Harlow researches black holes by combining quantum mechanics and Einstein's theory of general relativity.

It&#8217;s no longer that we <em>don&#8217;t know</em> whether Trump and Pence will acknowledge a <a href="https://projects.fivethirtyeight.com/2020-election-forecast/">likely loss</a>&#8212;rather, it&#8217;s that <em>we know they won&#8217;t</em>. They were repeatedly asked; we all heard their answers.</p> <p>That means that the <em>best</em> case, the ideal scenario, is already without precedent in the country&#8217;s 240-year history. It&#8217;s a president who never congratulates the winner, who refuses to meet him or coordinate a transfer of power, who skips the inauguration, and who&#8217;s basically dragged from the White House on January 20, screaming to his supporters (and continuing to scream until his dying breath) that the election was faked.</p> <p>As I said, that banana-republic outcome is now the <em>best</em> case. But it&#8217;s also plausible that Trump simply declares himself the winner on election night, because the mail-in votes, urban votes, yet-to-be-counted votes, or any other votes that trend the wrong way are fake; social media and the Murdoch press amplify this fantasy; Trump calls on Republican-controlled state legislatures to set aside the &#8220;rigged&#8221; results and appoint their own slates of electors; the legislatures dutifully comply; and the Supreme Court A-OKs it all. If you think none of that could happen, <a href="https://www.theatlantic.com/magazine/archive/2020/11/what-if-trump-refuses-concede/616424/?utm_source=facebook&amp;utm_medium=social&amp;utm_campaign=share&amp;fbclid=IwAR28w8ZJIZSlvqoOT-To3UWgMj4wVc9PkDA7Vbs60S_J7T0kOo1_RyVGe98">read this <em>Atlantic</em> article</a> from a few weeks ago, carefully to the end, and be more terrified than you&#8217;ve ever been in your life. And don&#8217;t pretend that you know what would happen next.</p> <p>I know, I know, I&#8217;m mentally ill, it&#8217;s Trump Derangement Syndrome, I see Nazis behind every corner just because they killed most of my relatives, a little global pandemic here and economic collapse there and riots and apocalyptic fires and resurgent fascism and I act as though it&#8217;s the whole world coming to an end. A few months from now, after everything has gone swimmingly, this post will still be here and you can come back and tell me how crazy I was. I accept that risk.</p> <p>For now, though, the best chance to avert a catastrophe is for Trump not merely to lose, but <strong>lose in a landslide that&#8217;s already clear by election night</strong>. Which means: as Michelle Obama <a href="https://www.vox.com/2020/8/18/21373177/michelle-obama-dnc-2020-speech-voting-post-office">advised</a> already in August, put on your mask, brave the virus, and vote in person if you can&#8212;<em>especially</em> if you live in a state that&#8217;s in play, and that won&#8217;t start tallying mail-in ballots till after election day. If your state allows it, vote early, when lines are shorter. That&#8217;s what Dana and I plan to do tomorrow; Texas <a href="https://www.washingtonpost.com/outlook/2020/10/04/joe-biden-win-texas/">going blue</a> on election night would be one dramatic way to foreclose shenanigans. If you can&#8217;t vote in person, or if your state counts mail-in ballots earlier, then vote by mail or drop-box, but <em>do it now</em>, so you have a chance to fix any problems well before Election Day.

In a quantum computer, the information itself is quantum mechanical and fragile, requiring new strategies to simultaneously process and communicate information.&nbsp;</p> <p>“Superconducting qubits are a leading technology today, but they generally support only local interactions (nearest-neighbor or qubits very close by). The question is how to connect to qubits that are at distant locations,” says William Oliver, an associate professor of electrical engineering and computer science, MIT Lincoln Laboratory fellow, director of the Center for Quantum Engineering, and associate director of the Research Laboratory of Electronics. “We need quantum interconnects, ideally based on microwave waveguides that can guide quantum information from one location to another.”</p> <p>That communication can occur via the microwave transmission line, or waveguide, as the excitations stored in the qubits generate photon pairs, which are emitted into the waveguide and then travel to two distant processing nodes. The identical photons are said to be “entangled,” acting as one system. As they travel to distant processing nodes, they can distribute that entanglement throughout a quantum network.</p> <p>“We generate the entangled photons on demand using the qubits and then release the entangled state to the waveguide with very high efficiency, essentially unity,” says Oliver.</p> <p>The research reported in the <em>Science Advances</em> paper utilizes a relatively simple technique, Kannan says.</p> <p>“Our work presents a new architecture for generating photons that are spatially entangled in a very simple manner, using only a waveguide and a few qubits, which act as the photonic emitters,” says Kannan. “The entanglement between the photons can then be transferred into the processors for use in quantum communication or interconnection protocols.”</p> <p>While the researchers said they have not yet implemented those communication protocols, their ongoing research is aimed in that direction.</p> <p>“We did not yet perform the communication between processors in this work, but rather showed how we can generate photons that are useful for quantum communication and interconnection,” Kannan says.&nbsp;</p> <p>Previous work by Kannan, Oliver, and colleagues introduced a waveguide quantum electrodynamics architecture using superconducting qubits that are essentially a type of artificial giant atom. That research demonstrated how such an architecture can perform low-error quantum computation and share quantum information between processors. This is accomplished by adjusting the frequency of the qubits to tune the qubit-waveguide interaction strength so the fragile qubits can be protected from waveguide-induced decoherence to perform high-fidelity qubit operations, and then readjusting the qubit frequency so the qubits are able to release their quantum information into the waveguide in the form of photons.</p> <p>This paper presented the photon generation ability of the waveguide quantum electrodynamics architecture, showing that the qubits can be used as quantum emitters for the waveguide. The researchers demonstrated that quantum interference between the photons emitted into the waveguide generates entangled, itinerant photons that travel in opposite directions and can be used for long-distance communication between quantum processors.</p> <p>Generating spatially entangled photons in optical systems is typically accomplished using spontaneous parametric down-conversion and photodetectors, but the generated entanglement achieved that way is generally random and therefore less useful in enabling on-demand communication of quantum information in a distributed system.</p> <p>“Modularity is a key concept of any extensible system,” says Oliver. “Our goal here is to demonstrate the elements of quantum interconnects that should be useful in future quantum processors.”</p> Michaela Jarvis | Research Laboratory of Electronics Entangled pairs of photons are generated by and propagate away from qubits placed along a waveguide.

There is a self-defeating double standard at work here, nationwide.<br>—Carl Sagan, <a href="https://www.amazon.com/Demon-Haunted-World-Science-Candle-Dark/dp/0345409469"><em>The Demon-Haunted World</em></a> (1996)</p></blockquote> <p>I’d like you to feel about the <a href="https://quillette.com/2020/09/23/rallying-to-protect-admissions-standards-at-americas-best-public-high-school/">impending destruction</a> of Virginia&#8217;s <a href="https://en.wikipedia.org/wiki/Thomas_Jefferson_High_School_for_Science_and_Technology">Thomas Jefferson High School for Science and Technology</a>, the same way you might&#8217;ve felt when the Taliban threatened to blow up the <a href="https://en.wikipedia.org/wiki/Buddhas_of_Bamyan">Bamyan Buddhas</a>, and then days later actually did blow them up. Or the way you felt when human negligence caused wildfires that incinerated half the koalas in Australia, or turned the San Francisco skyline into an orange hellscape. For that matter, the same way most of us felt the day Trump was elected. I’d like you to feel in the bottom of your stomach the <em>avoidability</em>, and yet the finality, of the loss.</p> <p>For thousands of kids in the DC area, especially first- or second-generation immigrants, TJHS represented a lifeline. Score high enough on an entrance exam—something hard but<em> totally within your control</em>—and you could attend a school where, instead of the other kids either tormenting or ignoring you, they might teach you Lisp or the surreal number system. Where you could learn humility instead of humiliation.</p> <p>When I visited TJHS back in 2012, to give a quantum computing talk, I toured the campus, chatted with students, fielded their questions, and thought: so <em>this</em> is the teenagerhood—the ironically <em>normal</em> teenagerhood—that I was denied by living someplace else. I found myself wishing that a hundred more TJHS’s, large and small, would sprout up across the country. I felt like if I could further that goal then, though the universe return to rubble, my life would’ve had a purpose.</p> <p>Instead, of course, our sorry country is destroying the few such schools that exist. <a href="https://www.nytimes.com/2019/06/24/nyregion/specialized-schools-nyc-deblasio.html">Stuyvesant and Bronx Science</a> in New York, and the Liberal Arts and Science Academy here in Austin, are also under mortal threat right now. The numerous parents who moved, who arranged their lives, specifically so that these schools might later be available for &#8220;high-risk&#8221; kids were suckered.</p> <p>Assuming you haven’t just emerged from 30 years in a Tibetan cave, you presumably know why this is happening. As of the <em>Washington Post</em>&#8216;s Jay Matthews <a href="https://www.washingtonpost.com/local/education/americas-top-sat-school-makes-another-disputed-attempt-at-diversity/2020/10/03/1bef3db2-0261-11eb-897d-3a6201d6643f_story.html?utm_campaign=wp_post_most&amp;utm_medium=email&amp;utm_source=newsletter&amp;wpisrc=nl_most&amp;carta-url=https%3A%2F%2Fs2.washingtonpost.com%2Fcar-ln-tr%2F2bf01fe%2F5f78a5d19d2fda0efb3d8031%2F5974cf76ade4e21a8497eeb1%2F42%2F62%2F2b179e7390f19bdba6f66f626ab37646">explains</a>, the Fairfax County School Board is “embarrassed” to have a school that, despite all its outreach attempts, remains only 5% Black and Latino&#8212;even though, crucially, the school <em>also</em> happens to be only 19% White (it’s now ~75% Asian).</p> <p>You might ask: so then why doesn&#8217;t TJHS just institute affirmative action, like almost every university does? It seems there&#8217;s an extremely interesting answer: <a href="https://www.washingtonian.com/2017/04/26/is-the-no-1-high-school-in-america-thomas-jefferson-fairfax-discrimination/">they did in the 1990s</a>, and Black and Hispanic enrollment surged. But then the verdicts of court cases, brought by right-wing groups, made the school district fear that they&#8217;d be open to lawsuits if they continued with affirmative action, so they dropped it. Now the boomerang has returned, and it’s time for a more drastic remedy: namely, to eliminate the TJHS entrance exam entirely, and replace it by a lottery for anyone whose GPA exceeds 3.5.</p> <p>The trouble is, TJHS without an entrance exam is no longer TJHS. More likely than not, such a place would simply converge to become another of the thousands of schools across the US where success is based on sports, networking, and popularity. And if by some miracle it avoided that fate, <em>still</em> it would no longer be available to most of the kids who‘d most need it.</p> <p>So yes, the district is <strong>embarrassed</strong>&#8212;note that the<em> Washington Post</em> writer explains it as if that’s the most obvious, natural reaction in the world&#8212;to host a school that&#8217;s regularly ranked #1 in the US, with the highest average SATs and a distinguished list of alumni. To avoid this embarrassment, the solution is (in effect) to burn the school to the ground.</p> <p>In a world-historic irony, the main effect of this “solution” will be to <strong>drastically limit the number of Asian students, while drastically <em>increasing</em> (!!!) the number of White students</strong>. The proportion of Black and Hispanic students is projected to increase a bit but remain small. Let me say that one more time: in practice, TJHS’s move from a standardized test to a lottery will be<strong> overwhelmingly pro-White, anti-Asian, and anti-immigrant</strong>; only as a much smaller effect will it be pro-underrepresented-minority.</p> <p>In spite of covid and everything else going on, hundreds of students and parents have been <a href="https://quillette.com/2020/09/23/rallying-to-protect-admissions-standards-at-americas-best-public-high-school/">protesting in front of TJHS</a> to try to prevent the school’s tragic and pointless destruction. But it sounds like TJHS&#8217;s fate might be sealed. The school board tolerated excellence for 35 more years than it wanted to; now its patience is at an end.</p> <p>Some will say: sure, the end of TJHS is unfortunate, Scott, but why do you let this stuff <em>weigh</em> on you so heavily? This is merely another instance of friendly fire, of good people fighting the just war against racism, and in <em>one</em> case hitting a target that, yeah, OK, probably should’ve been spared. On reflection, though, I can accept that only insofar as I accept that it was “friendly fire” when Bolsheviks targeted kulaks, or (much more comically, less importantly, and less successfully) when Arthur Chu, Amanda Marcotte, and a thousand other woke-ists targeted me. With friendly fire like that, who needs enemy fire?</p> <p>If you care about the gifted Black and Hispanic kids of Fairfax County, then like me, you should demand a change in the law to allow the reinstatement of affirmative action for them. You should acknowledge that the issue lies there and not with TJHS itself.</p> <p>I don’t see how you reach the point of understanding all the facts and still wanting to dismantle TJHS, over the desperate pleas of the students and parents, without a decent helping of resentment toward the kind of student who flourishes there—without a wish to see those uppity, “fresh off the boat” Chinese and Indian grinds get dragged down to where they belong. And if you tell me that you yourself were once that type of kid—well, isn’t that more contemptible still? Aren’t you knowingly burning a bridge you crossed so that a younger generation can&#8217;t follow you, basically reassuring the popular crowd that if they&#8217;ll only accept <em>you</em>, then there won&#8217;t be a hundred more greasy nerds in your tow? And if, on some level, you already know these things about yourself, then the only purpose of this post has been to remind you of them.</p> <hr class="wp-block-separator"/> <p>As for the news that dominates the wires and inevitably preempts what I&#8217;ve written: <strong>I wish for his successful recovery, followed by his losing the election and spending the rest of his life in New York State prison</strong>.

The answer seems obvious: for the same reason why a jilted ex is a more dangerous foe than a stranger. If <em>anyone</em> understood how to deprogram a Republican from the Trump cult, who would it be: Alexandria Ocasio-Cortez, or a fellow Republican who successfully broke from the cult?</p> <p>Do I agree with the Lincoln Republicans about most of the &#8220;normal&#8221; issues that Americans once argued about? Not at all. Do I hold them, in part, morally responsible for creating the preconditions to the current nightmare? Certainly.</p> <p>And should any of that cause me to boycott them? Not in my moral universe. If Churchill and FDR could team up with Stalin, then surely we in the Resistance can temporarily ally ourselves with the rare Republicans who chose their stated principles over power when tested&#8212;their very rarity attesting to the nontriviality of their choice.</p> <p>To my mind, turning one’s back on would-be allies, in a conflict whose stakes obviously overshadow what&#8217;s bad about those allies, is simultaneously one of the dumbest <em>and</em> the ugliest things that human beings can do. It abandons reason for moral purity and ends up achieving neither.</p> Announcements Rage Against Doofosity The Fate of Humanity Scott UArizona collaborates on $115M effort to build quantum computer https://news.arizona.edu/story/uarizona-collaborates-115m-effort-build-quantum-computer quantum computing – News urn:uuid:e146f3de-5ecb-1379-5b67-ef668bfeadc1 Tue, 15 Sep 2020 19:04:33 +0000 From University of Arizona, Sept. 2, 2020: Three University of Arizona researchers are involved in the Fermilab-hosted Superconducting Quantum Materials and Systems Center, which is part of a $625 million federal program to foster quantum innovation in the United States.

Today already, quantum cryptography can guarantee secure data transfer, albeit with limitations. The greatest possible compatibility with current silicon-based electronics will be a key advantage. And that is precisely where physicists have made progress: The team has designed a silicon-based light source to generate single photons that propagate well in glass fibers.
