Conditional preparation of two-mode correlated photon number states of light
Xu‐Bo Zou, Yuli Dong, Guang‐Can Guo · Physical Review A · 2006
We propose a scheme for conditional preparation of two-mode correlated photon number states of the form ${\ensuremath{\sum}}_{m=0}^{N}{C}_{m}\ensuremath{\mid}m{⟩}_{1}\ensuremath{\mid}m{⟩}_{2}$ by using linear optical elements and photon detectors. These states may find applications in testing Bell inequality based on quadrature using quadrature-phase homodyne measurement and optimize some quantum information processing protocols.
