Vector magnetic field sensing via multi-frequency control of nitrogen-vacancy centers in diamond
Sayaka Kitazawa, Yuichiro Matsuzaki, Saijo Soya +3
An ensemble of nitrogen-vacancy (NV) centers in diamond is an attractive device to detect small magnetic fields. In particular, by exploiting the fact that the NV center can be ali…
High resolution quantum sensing with shaped control pulses
J. Zopes, K. Sasaki, K. S. Cujia +5
We investigate the application of amplitude-shaped control pulses for enhancing the time and frequency resolution of multipulse quantum sensing sequences. Using the electronic spin…
Optimal control for perfect state transfer in linear quantum memory
Hideaki Nakao, Naoki Yamamoto
A quantum memory is a system that enables transfer, storage, and retrieval of optical quantum states by ON/OFF switching of the control signal in each stages of the memory. In part…
Noise suppression by quantum control before and after the noise
Hiroaki Wakamura, Ryûitirô Kawakubo, Tatsuhiko Koike
We discuss the possibility of protecting the state of a quantum system that goes through noise, by measurements/operations before and after the noise process. The aim is to seek fo…
