How quantum mechanics can change computing

In early July, Google announced that it will expand its commercially available cloud computing services to include quantum computing. A similar service has been available from IBM since May. These aren't services most regular ...

Physicists devise new approach to manipulate silicon 'qubits'

During their research for a new paper on quantum computing, HongWen Jiang, a UCLA professor of physics, and Joshua Schoenfield, a graduate student in his lab, ran into a recurring problem: They were so excited about the progress ...

Toward mass-producible quantum computers

Quantum computers are experimental devices that offer large speedups on some computational problems. One promising approach to building them involves harnessing nanometer-scale atomic defects in diamond materials.

Using graphene to create quantum bits

In the race to produce a quantum computer, a number of projects are seeking a way to create quantum bits—or qubits—that are stable, meaning they are not much affected by changes in their environment. This normally needs ...

Sound over silicon: Computing's wave of the future

With a combined $1.8 million from the W.M. Keck Foundation and the University of Arizona, materials science and engineering professor Pierre Deymier explores building a quantum computer that uses sound instead of quantum ...

Refrigerator for quantum computers discovered

The global race towards a functioning quantum computer is on. With future quantum computers, we will be able to solve previously impossible problems and develop, for example, complex medicines, fertilizers, or artificial ...

Trapped ions and superconductors face off in quantum benchmark

The race to build larger and larger quantum computers is heating up, with several technologies competing for a role in future devices. Each potential platform has strengths and weaknesses, but little has been done to directly ...
