Quantum computers have become the latest canvas for humanity’s oldest fantasy: escaping death. Startups, futurists, and ...

Physicists at Silicon Quantum Computing have developed what they say is the most accurate quantum computing chip ever engineered, after building a new kind of architecture.

IonQ ( IONQ +4.39%) and Rigetti Computing ( RGTI +4.12%) are both well down from the highs they touched in October: IonQ is off by around 43%, while Rigetti is down about 60% from its peak. Could ...

The true danger isn't just that quantum computers will read our emails. It's that they'll fundamentally change what's ...

Rapid advances in the kind of problems that quantum computers can tackle suggest that they are closer than ever to becoming ...

Quantum computing and neutron star physics are converging on the same hard problem: how to describe matter when gravity and quantum mechanics both refuse to stay in the background. Researchers are ...

Scientists map how quantum computer errors persist and link over time, revealing hidden memory that could reshape error ...

Quantum computing is entering a critical phase as researchers say scaling to millions of qubits is the biggest challenge and ...

There are currently about 80 companies across the world manufacturing quantum computing hardware. Because I report on quantum computing, I have had a chance to watch it grow as an industry from up ...

A new chip-scale device offers unprecedented control over laser frequencies, a key ingredient for large-scale quantum computing. Researchers have achieved an important step forward in quantum ...

A gold superconducting quantum computer hangs against a black background. Quantum computers, like the one shown here, could someday allow chemists to solve problems that classical computers can’t.

On May 7, 1981, influential physicist Richard Feynman gave a keynote speech at Caltech. Feynman opened his talk by politely rejecting the very notion of a keynote speech, instead saying that he had ...
