Quantum Memory Physicist
Qunett
About the role
Qunett is seeking a Quantum Memory Physicist to advance quantum memory capabilities based on the electron-nuclear spin register and spin-optical interface in group-IV color centers in diamond. This role owns day-to-day operation of a memory testbed and will execute pulsed optical + microwave/RF experiments that leverage the color center spin-photon interface for near-term quantum networking primitives (e.g., optical spin state preparation and readout, coherent microwave spin manipulation, spin-photon entanglement). The successful candidate will be part of the core experimental team responsible for developing the diamond quantum memory products for quantum networking applications.
Required qualifications
- PhD in Physics, Applied Physics, EE, or closely related field
- Hands-on experience with optically active spin defects in solids (e.g. diamond color centers, SiC defects, rare-earth ions, hBN defect emitters, and related platforms)
- Background in laser spectroscopy and quantum optical characterization (e.g. PLE, linewidth/spectral diffusion, g(2) measurements, optical coherence and lifetime, count-rate budgets)
- Experience with optical, electronic, microwave, and RF instrumentation used for laser modulation, photon counting, and/or pulsed spin resonance experiments (e.g. AWGs, VNAs, IQ modulators, EOMs, AOMs, time taggers)
- Python-based automation/analysis used in a lab context (instrument control, experiment orchestration, calibration)
Preferred qualifications
- Direct experience with diamond color center nanophotonics (waveguides/cavities/nanopillars) experiments
- Experience with low temperature (<1K) cryogenic equipment
- Expertise in pulsed spin resonance techniques, including T1, T2, Rabi, Ramsey, CPMG
- Experience with magneto-optical characterization of spin-photon interfaces in color centers
- Experience with coherent quantum optical experiments (e.g. two-photon HOM interference)
- FPGA programming experience (e.g. Xilinx RFSoCs)
- Familiarity with quantum information theory concepts
