From computer chips to image sensors in cameras, today's technology is overwhelmingly based on a semiconductor called silicon. This technology has been shrinking for decades—think of early room-sized computers compared to today's...
Tech giant Microsoft unveiled a new computer chip on Wednesday that it says could transform everything from fighting pollution to developing new medicines, joining Google and IBM in arguing that the promise of quantum computing is closer...
As computer chips continue to get smaller and more complex, the ultrathin metallic wires that carry electrical signals within these chips have become a weak link. Standard metal wires get worse at conducting electricity as they get...
Leveraging the principles of quantum mechanics, quantum computers can perform calculations at lightning-fast speeds, enabling them to solve complex problems faster than conventional computers. In quantum technology applications such as...
A team of engineers, physicists and quantum specialists at Google Research has found that reducing noise to a certain level allows the company's sycamore quantum chip to beat classical computers running random circuit sampling (RCS).
A research team from Skoltech and Bergische Universität Wuppertal in Germany has created a universal NOR logical element (from NOT—a negation operator and OR—a disjunction operator).
Quantum information systems offer faster, more powerful computing methods than standard computers to help solve many of the world's toughest problems. Yet fulfilling this ultimate promise will require bigger and more interconnected...
Lynn Conway may hold the record for longest delay between being unfairly fired and receiving an apology for it. In 1968, IBM—a company that now covers its logo in a rainbow flag each June for Pride Month—fired Conway when she expressed...
Researchers have created a unique wristwatch that contains multiple modules, including a sensor array, a microfluidic chip, signal processing, and a data display system to monitor chemicals in human sweat. Their study is published in the...
Researchers from the University of Basel and the NCCR SPIN have achieved the first controllable interaction between two hole spin qubits in a conventional silicon transistor. The breakthrough opens up the possibility of integrating...
A team of researchers led by the University of Massachusetts Amherst has drawn inspiration from a wide variety of natural geometric motifs—including those of 12-sided dice and potato chips—in order to extend a set of well-known design...
It has been known for centuries that light exhibits wave-like behavior in certain situations. Some materials are able to rotate the polarization, i.e. the direction of oscillation, of the light wave when the light passes through the...
Researchers at ETH have managed to trap ions using static electric and magnetic fields and to perform quantum operations on them. In the future, such traps could be used to realize quantum computers with far more quantum bits than have...
The field of photonic integrated circuits focuses on the miniaturization of photonic elements and their integration in photonic chips—circuits that carry out a range of calculations using photons, rather than electrons as are used in...
When we last checked in with Caltech's Kerry Vahala three years ago, his lab had recently reported the development of a new optical device called a turnkey frequency microcomb that has applications in digital communications, precision...
The hereditary molecule DNA can store a great deal of information over long periods of time in a very small space. For a good 10 years, scientists have therefore been pursuing the goal of developing DNA chips for computer technology, for...
Scientists led by Nanyang Technological University, Singapore (NTU Singapore) investigators have made a significant advance in developing alternative materials for the high-speed memory chips that let computers access information quickly...
The laser is so small you need a microscope to see it properly. But it's not just the size that scientists at Sandia National Laboratories are excited about.
A laser pulse surfing in the wake of an electron beam pulse could get upshifted from visible to extreme ultraviolet light, simulations done at the University of Michigan have shown.
It's been a turbulent year for cryptocurrency. Crypto giant FTX is just the latest in a slew of bankruptcies, collapsing spectacularly after a run on the company and a mad scramble to recover customer assets. Once worth $32 billion, it...
Computer chips are packed with billions of microscopic transistors that enable powerful computation, but also generate a great deal of heat. A buildup of heat can slow a computer processor and make it less efficient and reliable....
On-chip laser frequency combs—lasers that emit multiple frequencies or colors of light simultaneously separated like the tooth on a comb—are a promising technology for a range of applications including environmental monitoring, optical...
The silicon-based computer chips that power our modern devices require vast amounts of energy to operate. Despite ever-improving computing efficiency, information technology is projected to consume around 25% of all primary energy...
Stanford University researchers have developed a key experimental device for future quantum physics-based technologies that borrows a page from current, everyday mechanical devices.
The female genital tract can be a hostile environment for conception. Out of about 100 million sperm, only a few hundred make it to the fallopian tubes. Guided by a directional movement called rheotaxis, sperm cells swim against the...
The microscopic components that make up computer chips must be made at staggering scales. With billions of transistors in a single processor, each made of multiple materials carefully arranged in patterns as thin as a strand of DNA,...
The disruption in the global supply chain that caused shortages in everything from coffee to automotive parts to computer chips beginning in mid-2019 will be around for at least a few more months, according to most experts.
