A new federal initiative to build a quantum supercomputer could transform everything from encryption to drug discovery, creating the next wave of winners and losers.

Four decades ago, physicists were theorizing that the mind-bending mechanics of quantum physics could be harnessed to make a new kind of computer that’s exponentially more powerful than conventional machines.

The White House has issued an executive order aiming to unify and accelerate U.S. development of quantum technologies, including space systems that could enable next-generation navigation, sensing and secure communications.

Researchers from the University of Sydney, working with IBM, have identified and quantified important factors limiting the performance of quantum computers and demonstrated ways to overcome their impact.

The races that decide who wins the next decade rarely look like races. There is no finish line you can watch, no scoreboard on the evening news. There is only a slow buildup of advantage inside some laboratory,

Quantum science and AI research are big winners just a year after this U.S. funding giant slashed its Graduate Research Fellowship Program awards in half Researchers have developed a way to flip time to move backward in a quantum system. This level of control could lead to bizarre real-world applications

A team of theoretical researchers has found duality can unveil non-invertible symmetry protected topological phases, which can lead to researchers understanding more about the properties of these phases, and uncover new quantum ... An old puzzle in ...

Quantum computers are coming. Or, at least, that’s what current predictions say. These machines harness the power of quantum mechanics, the set of rules governing how physics operates at atomic and sub-atomic scales.

The city is betting on a promising—but commercially unproven—technology.
