In the fast-evolving world of quantum computing, one of the biggest hurdles isn’t how fast calculations can be done—it’s how long you can hold onto the delicate quantum information in the first place.

The tech company recently acquired the former Earthlink site, prompting concern over the impact of a potential data center.

A team of Caltech scientists has fabricated a superconducting qubit on a chip and connected it to a tiny device that scientists call a mechanical oscillator. Essentially a miniature tuning fork, the ...

Scientists demonstrate a new quantum chip architecture for suppressing errors using a type of qubit known as a cat qubit. Scientists based at the AWS Center for Quantum Computing on Caltech's campus ...

Researechers are testing superconducting microwire single-photon detectors (SMSPDs) for use in future particle physics exepriments. The detectors, which were designed and fabricated at JPL and ...

Quantum computers promise to outperform today's traditional computers in many areas of science, including chemistry, physics, and cryptography, but proving they will be superior has been challenging.

Inside a secretive set of buildings in Santa Barbara, California, scientists at Alphabet are working on one of the company's most ambitious bets yet. They're attempting to develop the world's most ...

How we talk about quantum systems depends crucially on how Hilbert space is factorized, or equivalently on a set of preferred observables. We tackle the question, given a finite-dimensional Hilbert ...
