The race to build reliable quantum computers is fraught with obstacles, and one of the most difficult to overcome is related ...

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 ...

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

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 ...

The order outlines a widespread effort to plan for increased quantum innovation, private sector cooperation and international partnership in pursuit of a quantum computer for scientific applications ...

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

Quantum communication has long promised unbreakable encryption, but the hardware has struggled to escape the lab. A new generation of laser-written glass chips is changing that equation, carving three ...

Are the mysteries of quantum mechanics finally starting to crack, or are we just getting better at asking sharper questions? Since the 2022 Nobel Prize in Physics honored experiments on quantum ...

Researchers have managed to read information stored in Majorana qubits, which are a form ...

Artificial intelligence changed how decisions are made. Quantum computing will decide whether those decisions remain secure.

A breakthrough optical design allows quantum computers to read information in parallel, a key step toward building ...

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