Balancing efficiencies by squeezing in realistic eight-port homodyne detection
Juha-Pekka Pellonpää, Jussi Schultz, Matteo G. A. Paris
We address measurements of covariant phase observables (CPOs) by means of realistic eight-port homodyne detectors. We do not assume equal quantum efficiencies for the four photodet…
Tilted phase space measurements
Pekka Lahti, Jussi Schultz
We show that the phase shift of π/2 is crucial for the phase space translation covariance of the measured high-amplitude limit observable in eight-port homodyne detection. However,…
Inefficient eight-port homodyne detection and covariant phase space observables
Pekka Lahti, Juha-Pekka Pellonpää, Jussi Schultz
We consider the quantum optical eight-port homodyne detection scheme in the case that each of the associated photon detectors is assigned with a different quantum efficiency. We gi…
