Quantum field theory (QFT) is a physics framework that describes how particles and forces behave based on principles rooted ...

Spin selectivity of transitions has now been demonstrated in a two-dimensional hole gas microcavity system, paving the way towards the study of new spin physics phenomena in hybrid excitations.

We demonstrate the first four-state DM CVQKD system generating composable secure keys over 20 km fiber, marking progress toward practical, high-performance, cost-effective, and highly secure QKD ...
