Josephson junctions, comprising two superconducting electrodes separated by a thin insulating barrier, underpin a broad range of quantum technologies. The coherent tunnelling of Cooper pairs across ...

For years, researchers have tried various ways to coax quantum bits—or qubits, the basic building blocks of quantum computers—to remain in their quantum state for ever-longer times, a key step in ...

Optical coherence extends beyond lasers, with partially coherent light enhancing imaging, communication, and photonic ...
