Quantum circuits are supposed to gain power as they grow longer, but noise changes the picture. A new study finds that earlier steps in these circuits gradually lose their impact, with only the final ...

BTQ Technologies Corp. has published a landmark research paper that establishes the physical and economic reality of using ...

New research suggests that a quantum computer could crack a crucial cryptography method with just 10,000 qubits.

Andhra Pradesh is set to launch India's first indigenously built, open-access quantum computers, marking a significant step ...

Quantum computers struggle with a major flaw: their information vanishes unpredictably. Scientists have now created a new method that can measure this loss over 100 times faster than before. By ...

Quantum computing is no longer a physics experiment. Google’s Willow chip, IBM’s quantum roadmap expansion, and IonQ’s ...

Pure play IonQ holds the world record for the most accurate quantum computing. Microsoft and Alphabet serve as excellent ...

A theoretical study shows that quantum excitations without topological protection, previously considered experimental limitations, can serve as spectroscopic tools for identifying quantum statistics.

One paper finds that attacking the bitcoin blockchain through quantum mining would demand the energy output of a star.

A theoretical paper posted to arXiv proposes that quantum coherence, the fragile property that powers quantum computing and ...

The Wisconsin Union Directorate welcomed renowned quantum physicist John Martinis to Shannon Hall on March 23 as part of the ...
