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

New research indicates that, with the right hardware, cracking Bitcoin's encryption is getting closer to being possible.

Most simplifies the complex process of quantum computing as "it can be 0 and 1 at the same time." That is not an explanation ...

Two companies that are racing to develop a photonic quantum computer using photonic qubits are PsiQuantum, based in Palo Alto ...

A consensus attack on the chain could compromise its proof-of-stake (PoS) system, the mechanism by which validators ...

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

Quantum computing, on the cusp of a technological revolution, is set to significantly alter the way we process and interact with data. The latest quantum computer has implications far beyond the ...

Quantum processors operate in environments engineered to eliminate nearly all external interference. That just might make them perfect dark matter detectors.

There are currently about 80 companies across the world manufacturing quantum computing hardware. Because I report on quantum computing, I have had a chance to watch it grow as an industry from up ...

Alexa von Tobel is fully aware that her big bet on quantum computing may never pay off. “The risk of being too early is a real risk,” she says. She’s speaking to me via Zoom from the New York City ...
