Qunett is hiring a Senior Quantum Control Physicist to design, build, and operate the coherent control stack for our diamond quantum memory — the microwave/RF, optical, and cryogenic hardware that initializes, manipulates, and reads out electron-nuclear spin registers in group-IV color centers. Day to day, this means running pulsed control experiments (Rabi, Ramsey, dynamical decoupling, multi-qubit gates on the spin register), diagnosing noise and error sources, and iterating on hardware to push fidelity, speed, and robustness.
