By using controlled microwave noise, researchers created a quantum refrigerator capable of operating as a cooler, heat engine, or amplifier. This approach offers a new way to manage heat directly ...

The low-noise, high-gain properties needed for high-performance quantum computing can be realized in a microwave photonic circuit device called a Josephson traveling-wave parametric amplifier (JTWPA), ...

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 ...

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