Researchers at ETH have demonstrated a new technique for carrying out sensitive quantum operations on atoms. In this technique, the control laser light is delivered directly inside a chip. This should make it possible to build...
As computer chips and other electronic devices continue to shrink in size, they become ever more sensitive to contamination. However, detecting the nanoscale equivalent of a water spot on a window is incredibly challenging. It is...
According to current estimates, the amount of data produced by humans and machines is rising at an exponential rate, with the digital universe doubling in size every two years. Very likely, the magnetic and optical data-storage systems...
Researchers from EPFL's Photonics Systems Lab have come up with a way of reconfiguring microwave photonic filters without the need for an external device. This paves the way for more compact, environmentally friendly filters that will be...
Last year, Google produced a 53-qubit quantum computer that could perform a specific calculation significantly faster than the world's fastest supercomputer. Like most of today's largest quantum computers, this system boasts tens of...
"Beam me up" is one of the most famous catchphrases from the Star Trek series. It is the command issued when a character wishes to teleport from a remote location back to the Starship Enterprise.
Most quantum computers being developed around the world will only work at fractions of a degree above absolute zero. That requires multi-million-dollar refrigeration and as soon as you plug them into conventional electronic circuits...
The rapid progression of technology has led to a huge increase in energy usage to process the massive troves of data generated by devices. But researchers in the Cockrell School of Engineering at The University of Texas at Austin have...
To develop futuristic technologies like quantum computers, scientists will need to find ways to control photons, the basic particles of light, just as precisely as they can already control electrons, the basic particles in electronic...
In a step toward practical quantum computing, researchers from MIT, Google, and elsewhere have designed a system that can verify when quantum chips have accurately performed complex computations that classical computers can't.
The development of technologies which can process information based on the laws of quantum physics are predicted to have profound impacts on modern society.
Researchers at the National Institute of Standards and Technology (NIST) and their colleagues have developed an optical switch that routes light from one computer chip to another in just 20 billionths of a second—faster than any other...
Amid the zoo of biomolecules essential to life, enzymes are among the most vital. Without these specialized proteins, which speed up the rates of chemical reactions, thousands of essential life processes, from cell growth and digestion...
Researchers have created a silicon carbide (SiC) photonic integrated chip that can be thermally tuned by applying an electric signal. The approach could one day be used to create a large range of reconfigurable devices such as...
Implementing quantum materials in computer chips provides access to fundamentally new technologies. To build high-performance quantum computers, for example, topological insulators have to be combined with superconductors. This...
It's estimated that as much as two-thirds of energy consumed in the U.S. each year is wasted as heat. Take for example, car engines, laptop computers, cell phones, even refrigerators, that heat up with overuse.
University of Twente spinoff company QuiX is currently developing a photonic chip using the quantum properties of light for carrying out complex calculations. The new chip, of which a first version is already operational, calculates...
Controlling individual droplets leads to more efficient self-cleaning surfaces and lab-on-a-chip implementations. University of Groningen professor Patrick Onck and colleagues from Eindhoven University of Technology have shown that this...
Field-programmable gate arrays (FPGAs) are kind of like a computer manufacturer's Lego bricks: electronic components that can be employed in a more flexible way than other computer chips. Even large data centers that are dedicated to...
Struggling Japanese engineering firm Toshiba on Monday reported improved full-year net profit thanks to the sale of its chip business, but said operating profit was sharply down.
A team of researchers from the University of Münster, the University of Oxford and the University of Exeter has built an all-optical neural network on a single chip. In their paper published in the journal Nature, the group describes...
University of Copenhagen researchers have developed a nanocomponent that emits light particles carrying quantum information. Less than one-tenth the width of a human hair, the miniscule component makes it possible to scale up and could...
Quickly transferring energy from one place to another—without loss—could fundamentally change solar panels and computers. Materials made from long chains of tiny particles, or nanoparticles, show promise for such energy transfer....
For the first time, researchers have used tiny gears made of germanium to generate a vortex of twisted light that turns around its axis of travel much like a corkscrew. Because germanium is compatible with the silicon used to make...
Scientists have long known that synthetic materials—called metamaterials—can manipulate electromagnetic waves such as visible light to make them behave in ways that cannot be found in nature. That has led to breakthroughs such as...
Computer scientists develop algorithms that control everything from unmanned aerial vehicles to desktop computers to the cellphones in our pockets. But it can be complicated to match the code they develop to hardware systems that vary so...
Quantum computers that are capable of solving complex problems, like drug design or machine learning, will require millions of quantum bits—or qubits—connected in an integrated way and designed to correct errors that inevitably occur in...
A new study by scientists from the University of Bristol brings us a significant step closer to unleashing the revolutionary potential of quantum computing by harnessing silicon fabrication technology to build complex on-chip quantum...
