Spin bath mediated long-lived coherent oscillations of NV centers in diamond
Akshat Rana, Pooja Lamba, Basanta Mistri +3
Decoherence is the biggest bottleneck in all quantum technologies. For nitrogen-vacancy (NV) centers in diamond, the loss of coherence is caused by the electron and nuclear spin ba…
Phonon-bottlenecked spin relaxation of Er:CaWO at milliKelvin temperatures
S. Rajendran, B. Mistri, P. K. Sharma +5
We study spin-lattice relaxation times of electron spins in Er:CaWO at millikelvin temperature, detected via their coupling to a low-mode volume superconducting resonato…
Clock-transition-enabled long electron spin coherence of telecom emitters in CeO
