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 ...

A new theoretical study has taken a close look at how noise influences these circuits. The results show that noise places a ...

Traditional encryption methods have long been vulnerable to quantum computers, but two new analyses suggest a capable enough ...

QuEra Computing today open-sourced its T-gate simulator (Tsim), a GPU-accelerated quantum circuit simulator that, for the first time, lets researchers simulate non-Clifford gate operations at the ...

Google published a paper on March 31 that states that Bitcoin's cryptography could be impacted by quantum computing sooner ...

Researchers from Caltech and Oratomic, a Caltech-linked startup, published findings on March 31, 2026, arguing that a useful quantum computer capable of running Shor’s algorithm on real cryptographic ...

Building a utility-scale quantum computer that can crack one of the most vital cryptosystems—elliptic curves—doesn’t require ...

Imagine you're trying to build a very long, complicated chain of dominoes. The aim is that each domino hits the next one ...

Quantum computers of the future may be closer to reality thanks to new research from Caltech and Oratomic, a Caltech-linked start-up company. Theorists and experimentalists teamed up to develop a new ...

A joint research team between the Center for Quantum Information and Quantum Biology (QIQB) at The University of Osaka and Fixstars Corporation has demonstrated one of the world's largest classical ...

These companies possess potent technologies, but one looks like the superior investment.
