Abstract

Quantum coherence is critical resource for applications in quantum technology, among which quantum-enhanced sensing represents a typical example.Compared with quantum metrology with entangled states of multiple qubits, bosonic interferometers have the advantage of being hardware-effcient, enabled by exploiting the high-dimensional Hilbert space of a bosonic mode.
