Entanglement-enhanced quantum metrology via alternating in-phase and quadrature modulation
Jihao Ma, Jiahao Huang, Chaohong Lee
Quantum metrology harnesses quantum entanglement to improve measurement precision beyond standard quantum limit. Although nonlinear interaction is essential for generating entangle…
