Quantum Memory Physicist

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 ( 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 Qunett
