Quantum computers are alternative computing devices that process information, leveraging quantum mechanical effects, such as entanglement between different particles. Entanglement establishes a link ...

Devices that can confine individual electrons are potential building blocks for quantum information systems. But the electrons must be protected from external disturbances. RIKEN researchers have now ...

At the smallest scales of matter, nature behaves in ways that feel almost counterintuitive. Individual particles follow ...

Your days of being frustrated by a sluggish smartphone or laptop could be coming to an end: scientists have discovered a new technique for controlling electronic states in quantum materials that could ...

Just a few years ago, many researchers in quantum computing thought it would take several decades to develop machines that ...

Concerns that quantum computers may start easily hacking into previously secure communications has motivated researchers to ...

A laser-written glass chip shows how fragile quantum signals can be decoded with high stability and low loss, offering a new ...

The study shows that in quantum devices, reading a clock consumes far more energy than running it. This insight will help ...

To push beyond this boundary, the team developed a quantum repeater system capable of creating memory–memory entanglement between two separate nodes. By linking these nodes through entanglement ...

The Quantum Systems Accelerator (QSA), a National Quantum Information Science Research Center funded by the U.S. Department of Energy Office of Science, takes a science-first approach to exploring new ...

Superconducting quantum devices and arrays constitute a cutting‐edge field at the intersection of superconductivity and quantum mechanics. These systems utilise superconducting circuits—typically ...

Scientists do not know what dark matter is made of but they believe it leaves signals, and those signals could be captured by quantum devices.
