While many plans for quantum computers transmit data using the particles of light known as photons, researchers from the ...

When most people imagine quantum computers, they think of machines that use particles of light, called photons, to process ...

Quantum physics just pulled off a rewind trick that sounds like sci-fi. Here’s what the experiment actually did—and why it ...

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.

Researchers find that a photon can spend a negative amount of time in an excited atomic state while passing through a cloud ...

Believe it or not, the quantum vacuum... isn't completely empty. It has tiny vibrations or “sparks” of energy. If an object ...

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 ...

An exhibit of a quantum computer at O’Hare put on by the University of Chicago and IBM aims to make learning about the ...
