Researchers have demonstrated that the theoretically optimal scaling for magic state distillation—a critical bottleneck in fault-tolerant quantum computing—is achievable for qubits, improving on the ...

The big picture: The Commerce Department is weighing a funding model that would make Washington a direct shareholder in US quantum-computing firms, a move that signals a deeper shift in how the ...

A recent Wall Street Journal report has sparked major renewed interest in the quantum computing sector, claiming that President Trump is pushing for the U.S. government to acquire ownership stakes in ...

For quantum computers to change the game of computation, scientists need to show that the machines’ calculations are correct. Now, there’s hope. Google’s Willow quantum chip has achieved verifiable ...

Shares of Wall Street's pure-play quantum computing darlings -- IonQ, Rigetti Computing, D-Wave Systems, and Quantum Computing, Inc. -- have soared 620% to 5,710% over the trailing year. History is ...

Quantum computing investing encompasses a wide variety of businesses. The quantum computing space is really starting to heat up. Many of the top picks surged during September, leaving investors ...

Quantum Computing sold 26.87 million shares -- a very specific number -- for $500 million last week. This week, someone else is selling 26.87 million Quantum Computing shares. 10 stocks we like better ...

A team of Harvard physicists built the first-ever quantum computing machine that can operate continuously without restarting, achieving a major breakthrough in a field that could revolutionize ...

IBM’s quantum computing capabilities are still underappreciated. The market has been pouring into quantum computing startups, but they may be missing the forest for the trees. IBM has dominated the ...

Quantum Computing is still in its infancy, more of an idea and research project than a functioning industry. The technology has incredible potential, from breaking encryption to drug discovery, but ...

A device with more than 6000 quantum bits, or qubits, has smashed a previously-held record and is the first step towards building the largest quantum computer yet. Each of these is a neutral caesium ...

Quantum computers are powerful, but a practical quantum machine that’s useful for everyday tasks remains elusive. In fact, proponents of quantum computing say it could be another 10 years before there ...
