Two-dimensional projection of a quantum spherical code composed of two copies (black and red) of the four complex dimensional Witting polytope. This code can correct up to five photon losses of any ...

Quantum computing might sound like the kind of sci-fi plot device used to explain how a character traveled through time or shrank to the size of an ant. But the technology is very real, and Silicon ...

Quantum computers are computing systems that process information leveraging quantum mechanical effects. These computers rely ...

Today’s quantum computing hardware is severely limited in what it can do by errors that are difficult to avoid. There can be problems with everything from setting the initial state of a qubit to ...

One day soon, at a research lab near Santa Barbara or Seattle or a secret facility in the Chinese mountains, it will begin: the sudden unlocking of the world’s secrets. Your secrets. Cybersecurity ...

Pure-plays like IonQ, Rigetti Computing, and D-Wave Quantum remain the most popular opportunities in quantum computing at the ...

The U.S. government recently designated Colorado a regional tech hub for the quantum industry. That puts the state in line to receive a federal grant as part of the CHIPS and Science Act, which aims ...

Quantum computers are expected to solve some problems beyond the reach of the most powerful supercomputers imaginable. Reaching this milestone has been dubbed "quantum supremacy." But whether quantum ...
