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.

Quantum computers work by applying quantum operations, such as quantum gates, to delicate quantum states. Ideally, quantum ...

Quantum computing may sound like science fiction, but it’s here today, and it represents the shiny new thing in high ...

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 ...
