Scientists led by the University of Massachusetts Amherst have adapted a device called a microwave circulator for use in quantum computers, allowing them for the first time to precisely tune the exact degree of nonreciprocity ...
The fragile qubits that make up quantum computers offer a powerful computational tool, yet also present a conundrum: How can engineers create practical, workable quantum systems out of bits that are so easily disturbed—and ...
Radiation from space is a challenge for quantum computers as their computation time becomes limited by cosmic rays. Researchers from Chalmers University of Technology, Sweden, and University of Waterloo in Canada are now ...
Entanglement is a form of correlation between quantum objects, such as particles at the atomic scale. The laws of classical physics cannot explain this uniquely quantum phenomenon, yet it is one of the properties that explain ...
Researchers simulated a key quantum state at one of the largest scales reported, with support from the Quantum Computing User Program, or QCUP, at the Department of Energy's Oak Ridge National Laboratory.
Quantum computers, systems that process and store information leveraging quantum mechanical phenomena, could eventually outperform classical computers on numerous tasks. Among other things, these computers could allow researchers ...
It's Saturday, which means that in a universe where the arrow of time moves backward, people have to go to work tomorrow. In such a hypothetical universe, Garfield hates Fridays—tough to imagine. This week, we looked at ...
Chasing ever-higher qubit counts in near-term quantum computers constantly demands new feats of engineering.
Seeking a method for reducing error in noisy quantum systems, Kajsa Williams and Louis-S. Bouchard, researchers at the Center for Quantum Science and Engineering at the University of California, Los Angeles, implemented and ...
Rice University physicists have discovered a phase-changing quantum material—and a method for finding more like it—that could potentially be used to create flash-like memory capable of storing quantum bits of information, ...
