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.

Quantum computers need extreme cold to work, but the very systems that keep them cold also create noise that can destroy fragile quantum information. Scientists in Sweden have now flipped that problem ...

Media coverage of the threat posed by quantum computing usually identifies cryptocurrencies as a key area of classical cryptography that will be effortlessly broken when the technology hits the ...

Microsoft and Alphabet have resources that quantum computing pure-plays could only dream about. Nvidia has launched a device that allows for a hybrid quantum computing approach. All three of these ...

Quantum computing pure-play stocks IonQ, Rigetti Computing, D-Wave Quantum, and Quantum Computing Inc. have respectively skyrocketed up to 829% over the trailing year. Although quantum computers offer ...

They managed to cut the size of the AI reasoning model by more than half—and claim it can now answer politically sensitive questions once off limits in Chinese AI systems. A group of quantum ...

Google claims to have developed a quantum computer algorithm that is 13,000 times faster than the most powerful supercomputers. This would bring the technology another step closer to real-world ...

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 ...

Leaders and researchers in the quantum industry gathered at UC Berkeley’s California Memorial Stadium on Friday morning to launch Quantum California, a statewide private-public initiative to connect ...

One of the main obstacles to bringing a commercial quantum computer to market is reducing qubit error rates, the analog of bit error rates in the digital world. IBM ...

SAN FRANCISCO, Oct 24 (Reuters) - IBM (IBM.N), opens new tab said on Friday it can run a key quantum computing error correction algorithm on commonly available chips ...
