Application of adiabatic passage in NV-detected ESR and NMR

ORAL

Abstract

Precise control of a quantum system is a key in various fields. Adiabatic passage is a robust and efficient method for producing complete population transfer between two states of a quantum system. Although the duration of conventional adiabatic passage control is long and often hampered by quantum decoherence, the evolution can be accelerated significantly, so-called shortcuts to adiabaticity (STA).

In this presentation, we will discuss applications of STA in quantum sensing experiments using Nitrogen-Vacancy (NV) centers in diamond. STA pulses are less susceptible to pulse errors induced by thermal relaxation and field inhomogeneity, which is important in room-temperature quantum sensing using NV centers. In particular, implementation of STA shaped pulses in NV-detected electron spin resonance (ESR) and nuclear magnetic resonance (NMR) spectroscopy will be discussed.
