Quantum Computers

Scientists have developed a method for storing quantum information in a single dimension, thereby reducing decoherence, using chromium sulfide bromide.

A new technique improves the reliability of cat qubits by squeezing their probabilistic states. This could improve their reliability and lifetime, and pave the way for accurate quantum computing.

The exotic quantum phase, predicted over half a century ago, could lead to advances in quantum computing, sensors and communication technology.

Quantum superposition is a phenomenon in which a tiny particle can be in two states at the same time — but only if it is not being directly observed.

Physicists have replicated the famous Schrödinger's cat experiment at hotter temperatures than ever before. The breakthrough is a small but significant step toward quantum computers that can work at normal temperatures.

Useful quantum networks are hobbled by the problem of decoherence from environmental "noise." But a new breakthrough could change that.

A new device enables remote entanglement, allowing distant quantum processors to communicate with one another with reduced error rates.

U.S. government scientists have developed a new phase of matter dubbed 'half ice, half fire,' which unites opposing electron spins in a unique magnet.

This new superconducting prototype quantum processor achieved benchmarking results to rival Google's new Willow QPU.

Scientists have built the first networked quantum computer using photons, demonstrating that room-temperature modules can be connected and scaled up.
