Bell nonlocality with directly generated telecom-band spin–photon entanglement

Quantum nonlocality, typically revealed through entanglement distribution across quantum networks, is a cornerstone of quantum information science. Long-distance distribution of entanglement requires the information carrier, i.e. flying photons, to operate in the minimum-loss tel...

Superradiant phonon laser with collective spin control

Hybrid systems consisting of phonon resonators and solid-state spin ensembles offer a unique opportunity for the study of emerging driven-dissipative quantum many-body physics. Our theoretical analysis shows that in such a phonon-matter hybrid system, the interplay of coherent an...

Random access and high dimensional integrated quantum memory

Abstract Random-access quantum memory (RAQM) is a fundamental building block for scalable quantum networks and photonic quantum computing. While existing realizations rely on gaseous physical systems, solid-state platforms—particularly integrated architectures—offer distinct prac...
