Phase-correlation-free quantum key distribution source operating at gigahertz rates
Shashank Kumar, Alessandro Marcomini, Loïc Millet +10
Phase randomization is essential for the security of practical decoy-state quantum key distribution (QKD) systems. Commonly, implementations rely on laser sources which are either…

Magnetic field orientation dependence of continuous-wave optically detected magnetic resonance with nitrogen-vacancy ensembles
Pralekh Dubey, Shashank Kumar, Chinmaya Singh +5
Continuous-wave optically detected magnetic resonance (CW-ODMR) measurements with nitrogen-vacancy (NV) spins in diamond are used for sensing DC magnetic fields from nearby magneti…
