Photon statistical properties of multiple-photon-subtracted two-mode squeezed coherent states

We investigate how the combination of photon subtraction and coherent displacement affects the photon statistical properties of the multiple-photon-subtracted two-mode squeezed coherent states (PS-TMSCS). We find that the photon statistical properties are sensitive to the compound phase involved in the TMSCS. Our numerical analysis shows that the photon subtraction can enhance the cross-correlation and anti-bunching effects of the PS-TMSCS. Compared with that of the TMSCS, the photon number distribution of the PS-TMSCS is modulated by a factor that is a monotonically increasing function of the numbers of subtracting photons from each mode. And the photon subtraction essentially shifts the photon number distribution. Crown Copyright (C) 2013 Published by Elsevier B.V. All rights reserved.
