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.

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.

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 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.

The tech giant predicts it will have a quantum computer that can solve commercially useful problems by the end of the decade.

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

Quantum computing firm QuEra says it plans to make a fault-tolerant quantum computer and offer it to users through the cloud in 2028, which will require a real leap in engineering

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.

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. The most well-known problem in which quantum computers ...
