Quantum Absorbance Estimation and the Beer-Lambert Law
Euan J. Allen, Javier Sabines-Chesterking, Alex McMillan +3
The utility of transmission measurement has made it a target for quantum enhanced measurement strategies. Here we find if the length of an absorbing object is a controllable variab…
Quantum Optical Metrology of Correlated Phase and Loss
Patrick M. Birchall, Euan J. Allen, Thomas M. Stace +3
Optical absorption measurements characterize a wide variety of systems from atomic gases to \emph{in-vivo} diagnostics of living organisms. Here we study the potential of non-class…
Passive, broadband and low-frequency suppression of laser amplitude noise to the shot-noise limit using hollow-core fibre
Euan J. Allen, Giacomo Ferranti, Kristina R. Rusimova +6
We use hollow-core fibre to preserve the spectrum and temporal profile of picosecond laser pulses in CBD to suppress 2.6 dB of amplitude noise at MHz noise frequencies, to within 0…
