Overcoming inefficient detection in sub-shot-noise absorption measurement and imaging
E. Knyazev, F. Ya. Khalili, M. V. Chekhova
Photon-number squeezing and correlations enable measurement of absorption with an accuracy exceeding that of the shot-noise limit. However, sub-shot noise imaging and sensing based…
Quantum noise cancellation in asymmetric speed meters with balanced homodyne readout
T Zhang, E Knyazev, S Steinlechner +17
Sagnac speed meter (SSM) topology is known as an alternative technique to reduce quantum back-action in gravitational-wave interferometers. However, any potential imbalance of the…
Quantum tomography enhanced through parametric amplification
E. Knyazev, K. Yu. Spasibko, M. V. Chekhova +1
Quantum tomography is the standard method of reconstructing the Wigner function of quantum states of light by means of balanced homodyne detection. The reconstruction quality stron…
