Quantum Memory Physicist

About the role

Qunett is hiring an Experimental Quantum Physicist to advance the frontier of solid-state quantum memory based on group-IV color centers in diamond — with a focus on the electron-nuclear spin register and spin-optical interface that make these systems uniquely suited for real-world quantum networking.

You will take ownership of day-to-day operation of a memory testbed and lead pulsed optical and microwave/RF experiments targeting spin-photon entanglement, optical spin initialization and readout, and coherent spin manipulation. The experimental scope spans foundational characterization through networking-relevant implementation.

The successful candidate will join the core experimental team building Qunett's diamond quantum memory products for quantum networking.

Required qualifications

• PhD in Physics, Applied Physics, Electrical Engineering, or a closely related field
• Hands-on experimental experience with one or more quantum platforms, including solid-state spin defects, semiconductor spin systems, rare-earth ion ensembles or single ions, trapped ions, neutral atoms, quantum materials, or related systems
• Experience constructing and operating laser-based experimental systems, including optical alignment, laser modulation or stabilization, and single-photon detection
• Working knowledge of electronic and RF/microwave instrumentation in a lab setting (e.g., signal generators, AWGs, photon time taggers, lock-in amplifiers)
• Python or equivalent scripting for instrument control, data acquisition, or experimental analysis

Preferred qualifications

• Experience with optically active spin defects in solids (diamond color centers — NV, SiV, SnV; SiC defects; hBN emitters; rare-earth ions; or related systems)
• Background in laser spectroscopy and quantum optical characterization, including PLE, linewidth and spectral diffusion measurements, g(2) correlations, optical coherence, and excited-state lifetime
• Experimental experience with pulsed spin resonance: Rabi oscillations, Ramsey interferometry, T1, T2*, CPMG dynamical decoupling, or equivalent coherent control techniques
• Experience with cryogenic platforms, particularly sub-Kelvin systems
• Familiarity with nanophotonic device characterization, waveguide-coupled emitters, or confocal microscopy
• Experience with coherent quantum optical experiments such as two-photon Hong-Ou-Mandel interference or photon-mediated remote entanglement generation
