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

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 ...

Two research groups say they have significantly reduced the amount of qubits and time required to crack common online ...

Wave, the testnet has drawn 13,000 sign-ups and early work from six research teams, but remains an experimental environment ...

The clock is ticking on cryptocurrency.

Mid-circuit measurements are one of the biggest practical hurdles in quantum error correction on encoded qubits. Researchers in Innsbruck and Aachen have now proposed and experimentally demonstrated ...

Core to the approach is what the companies call a one-step simplified LBM, or OSSLBM, framework. The method uses a hybrid ...

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

New research suggests quantum computers capable of breaking internet encryption may arrive sooner than expected—with AI ...

According to a study by engineers at Caltech and the UC Department of Physics, quantum computers do not need to be nearly as ...

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 ...

In the quest to move quantum computing into practical use, researchers have developed a new understanding of qubit lifespans.
