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 ...

Quantum computing stocks are surging in midday trading on Tuesday, with the sector’s three most-watched pure-plays all ...

Imagine you're trying to build a very long, complicated chain of dominoes. The aim is that each domino hits the next one perfectly, all the way down the line, producing an amazing result at the end. A ...

As AI compute needs multiply, one quantum computing firm says it has the edge over Nvidia (NVDA). "If I was Nvidia, I'd be ...

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 ...

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 ...

D-Wave Quantum Inc. is rated Strong Sell with 12-month price target of $4.13, citing extreme overvaluation versus ...

The spin-off company ParityQC has implemented the largest quantum Fourier transform ever reported using an IBM quantum ...

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

On April 16, 2026, mounting interest in quantum AI applications, a surge in trading volume, and a bold CEO challenge to GPU ...

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

A new theoretical study involving EPFL shows how the noise in today’s quantum computers limits how much work their circuits can really do, and how this affects training and simulation.
