Quantum metrology & sensing
We develop protocols that extract more precision per resource — per photon, per qubit, per second of measurement time — by exploiting entanglement, squeezing, and optimal control.
This work is explicitly noise-aware: we ask what precision is achievable with realistic probes, finite data, and imperfect measurements, from single sensors to distributed sensor networks.
