Google just issued a warning that has great implications for the cybersecurity world: "Q-Day" — the moment when a quantum computer becomes powerful enough ...

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

However, it is not necessary to use fancy quantum cryptography technology such as entanglement to avoid the looming quantum ...

But RSA worked until the advent of quantum computers. These machines harness the physics of subatomic particles to process information in fundamentally different ways, including factoring long strings ...

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 University of Sydney quantum physicist has developed a new approach to quantum error correction that could significantly ...

A Gravity Theory That Could Rewrite the Universe’s First Moments The first fraction of a second after the Big Bang has always ...

By adapting ideas from gauge theory, the researchers show how quantum information spread-out across a machine can be measured using only local checks, significantly lowering computing overhead. Their ...

While Bitcoin developers scramble to find a solution and Ethereum prepares for Q-day, Solana is trying to get ahead of that ...

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 ...

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

This chip is another, tinier box inside of which takes place the phenomenon discovered by Albert Einstein and other ...
