Computer chips that cram billions of electronic devices into a few square inches have powered the digital economy and ...

A team of researchers spent years watching their quantum circuits fail before one finally worked. In early 2025, scientists ...

A new theoretical study has taken a close look at how noise influences these circuits. The results show that noise places a surprisingly strict limit on how deep a quantum circuit can be, meaning how ...

What are virtual circuits (VCs)? Why VCs are better than quantum computing. How chatbots can help in the design of VCs. Quantum computing promises to deliver impressive computing performance for ...

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 ...
