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…
Towards second-long electron spin coherence of a telecom quantum emitter in naturally abundant CeO
Basanta Mistri, Vishal Ranjan, Siddharth Dhomkar
Rare-earth-ion-doped crystals has emerged as a promising platform for quantum technologies, owing to their narrow telecom-band optical emission, long spin memory, and compatibility…
Identifying optimal magnetic field configurations for decoherence mitigation of boron vacancies in hexagonal boron nitride
Basanta Mistri, Saksham Mahajan, Felix Donaldson +2
The negatively charged boron vacancy center in 2D hexagonal boron nitride has emerged as a promising quantum sensor. However, its sensitivity is constrained due to ubiquitous nucle…
