Physical Resources for Quantum-enhanced Phase Estimation
Jaspreet Sahota, Nicolás Quesada, Daniel F. V. James
We study the role of quantum entanglement (particle entanglement and mode entanglement) in optical phase estimation by employing the first and second quantization formalisms of qua…

Quantum correlations in optical metrology: Heisenberg-limited phase estimation without mode entanglement
Jaspreet Sahota, Nicolás Quesada
The quantum fisher information and quantum correlation parameters are employed to study the application of non-classical light to the problem of parameter estimation. It is shown t…

Quantum-enhanced Phase Estimation with an Amplified Bell State
Jaspreet Sahota, Daniel F. V. James
We propose a phase estimation protocol for optical interferometry that employs a probe state (containing on average n photons) obtained by squeezing each mode, separately, of a sin…
