Photonic quantum metrology with variational quantum optical nonlinearities

Photonic quantum metrology with variational quantum optical nonlinearities

Photonic quantum metrology harnesses quantum states of light, such as NOON or twin-Fock states, to measure unknown parameters beyond classical precision limits. Current protocols suffer from two severe limitations that preclude their scalability: the exponential decrease in fidelities (or probabilit...
