Quantum computers hit a crucial milestone for error-free calculation The new record holder is a quantum computer called Jiuzhang 4.0 that makes calculations using particles of light, or photons.

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 ...

Quantum computers represent a breakthrough comparable to the move from valves to transistors in computer engineering. It doesn't just mean processing data faster; it means processing data in ways that ...

Inside a secretive set of buildings in Santa Barbara, California, scientists at Alphabet are working on one of the company's most ambitious bets yet. They're attempting to develop the world's most ...

Over the past year, vendor after vendor has reached the critical quantum-computing milestone where adding more qubits no longer adds a disproportionately higher amount of errors. “For the first time, ...

Making quantum computers fault-tolerant (and scaling effective error correction to enable this) is a key barrier to a new era of quantum supremacy. A new study ...

Teleportation is a reality in 2025 — well, at least for quantum computers. In February 2025, Oxford University demonstrated the teleportation of quantum data from one independent quantum processor to ...

Ramin Ayanzadeh joined CU Boulder’s Department of Computer Science as an assistant professor in the fall of 2024. His research focuses on trustworthy quantum computing to enhance the reliability and ...

Google has once again claimed the prestigious milestone of quantum supremacy, asserting that its latest quantum computer has outperformed classical counterparts in specific computational tasks. This ...

THE WhatsApp message from IBM was ominous: four to six inches of snow was expected over Troy, New York and many places nearby, including my temporary home base — in Poughkeepsie — where I camped out ...

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 ...
