Tuning atom-field interaction via phase shaping

2023 · arXiv (Cornell University)

A coherent electromagnetic field can be described by its amplitude, frequency, and phase. All these properties can influence the interaction between the field and an atom. Here we demonstrate the phase shaping of microwaves that …

Field test of quantum key distribution with high key creation efficiency

2023 · Optics Express

Quantum key distribution (QKD) promises unconditional security for communication. However, the random choices of the measurement basis in QKD usually result in low key creation efficiency. This drawback is overcome in the differential-phase-shift QKD, provided …
