New largest number factored on a quantum device is 56,153
Majorana fermion: Physicists observe elusive particle that is its own antiparticle
Princeton University scientists have observed an exotic particle that behaves simultaneously like matter and antimatter, a feat of math and engineering that could yield powerful computers based on quantum ...
Superposition revisited: Proposed resolution of double-slit experiment paradox using Feynman path integral formalism
How the physics of champagne bubbles may help address the world's future energy needs
Uncork a bottle of champagne, and as the pressure of the liquid is abruptly removed, bubbles immediately form and then rapidly begin the process of "coarsening," in which larger bubbles grow at the expense ...
Researchers find qubits based on trapped ions offer a promising scalable platform for quantum computing
Simon's algorithm run on quantum computer for the first time—faster than on standard computer
A piece of the quantum puzzle: High level of controllability needed to explore ideas in quantum simulations
While the Martinis Lab at UC Santa Barbara has been focusing on quantum computation, former postdoctoral fellow Pedram Roushan and several colleagues have been exploring qubits (quantum bits) for quantum ...
Heat transfer sets the noise floor for ultrasensitive electronics
A team of engineers and scientists has identified a source of electronic noise that could affect the functioning of instruments operating at very low temperatures, such as devices used in radio telescopes ...
Asteroid Apophis could experience landslides when it passes near Earth
Simulations show Eurasia more than twice as likely to have harsh winters due to sea ice melting
Physicists set new records for silicon quantum computing
Two research teams working in the same laboratories at UNSW Australia have found distinct solutions to a critical challenge that has held back the realisation of super powerful quantum computers.
New 'topological insulator' could lead to superfast computers
University of Utah engineers discovered a way to create a special material – a metal layer on top of a silicon semiconductor – that could lead to cost-effective, superfast computers that perform lightning-fast ...
A promising light source for optoelectronic chips can be tuned to different frequencies
Chips that use light, rather than electricity, to move data would consume much less power—and energy efficiency is a growing concern as chips' transistor counts rise.
Interactive dark matter could explain Milky Way's missing satellite galaxies
Scientists believe they have found a way to explain why there are not as many galaxies orbiting the Milky Way as expected.
