Research Physicist – Quantum magnetometry using photoelectrically detected magnetic resonance of NV centers in diamond

Overview

Quantum sensing based on optically active spin defects in semiconductors (color center spins) is an
emerging opportunity to deploy SI-traceable measurements in widespread application areas, including
transportation, medicine, and resource exploration. The Nanoscale Spectroscopy Group seeks a research
physicist to conduct optically and photoelectrically detected spin resonance sensing of magnetic fields
for such applications. The successful candidate will study the physics and control of color center spins
using a combination of metrologies, including optical and magnetic spectroscopies, advanced
microscopies, and simulations to develop quantum sensing platforms. With limited supervision, the
candidate will develop high-resolution spectral characterization of NV centers in diamond and other
color center spins; investigate promising new color center spins in systems such as GaN, Si, and SiC, etc.;
use judgment and literature precedents to research, interpret, and apply available guiding principles to
characterize nanoscale optical and spin measurements of color centers, including single-defect emission,
time-resolved detection, stroboscopic and spectroscopic methods, and nanoscale magnetometry using
diverse readout schemes. The candidate will also integrate Bayesian algorithms for efficient
measurements and develop automated measurement systems. The candidate will undertake numerical
modelling of spin dynamics to understand device performance and improve on sensor design. The work
impacts the goals of the nanoscale spectroscopy program to advance the development of engineered
artificial atoms for nanoscale sensing and quantum applications. The candidate will interact with a
broader team consisting of spectroscopy and materials chemistry expertise. The candidate will
disseminate research results through open literature publication and technical talks at conferences.
