"Quantum" may seem like a useless buzzword, but quantum computing is a real thing, and it's actually understandable even if ...

Quantum information theory is a field of study that examines how quantum technologies store and process information. Over the ...

Fully functional quantum computers remain out of reach, but optimism across the field is rising. At the Q2B Silicon Valley conference in December, researchers and executives ...

Governments and tech companies continue to pour money into quantum technology in the hopes of building a supercomputer that can work at speeds we can't yet fathom to solve big problems.

Bitcoin depends on encryption to remain secure. This encryption protects transactions, wallets, and user funds. If the ...

Rapid advances in the kind of problems that quantum computers can tackle suggest that they are closer than ever to becoming ...

Regardless of the answers, the era of entanglement under infinite book‐keeping is giving way to an era of entanglement under limited books, limited clocks and limited gates. And in this more realistic ...

Using a powerful machine made up of 56 trapped-ion quantum bits, or qubits, researchers have achieved something once thought impossible. They have proven, for the first time, that a quantum computer ...

Quantum computing is shifting from theory to risk for Bitcoin, sparking debate over timelines, security upgrades, and market ...
