New blueprint for more stable quantum computers

Researchers at the Paul Scherrer Institute (PSI) have put forward a detailed plan of how faster and better defined quantum bits—qubits—can be created. The central elements are magnetic atoms from the class of so-called ...

Performing optical logic operations by a diffractive neural network

Optical logical operations have sparked major interest in the past decade since they can enable many applications, particularly those involving high-throughput and on-the-fly data processing such as secured wireless communication ...

Quantum computers offer another look at classic physics concepts

"Think what we can do if we teach a quantum computer to do statistical mechanics," posed Michael McGuigan, a computational scientist with the Computational Science Initiative at the U.S. Department of Energy's Brookhaven ...

Heterostructure crystals could light the way to optical circuits

It may be possible to reach new levels of miniaturization, speed, and data processing with optical quantum computers, which use light to carry information. For this, we need materials that can absorb and transmit photons. ...

Physicists 'teleport' logic operation between separated ions

Physicists at the National Institute of Standards and Technology (NIST) have teleported a computer circuit instruction known as a quantum logic operation between two separated ions (electrically charged atoms), showcasing ...

Team harnesses spin of electrons to power tech devices

Building on the Air Force's need to develop tech devices that require minimal charging in the field, the University of Texas at San Antonio (UTSA) is using principles in quantum science and engineering to build a graphene-based ...
