Conditional quantum-state engineering using ancillary squeezed-vaccum states
We investigate an optical scheme to conditionally engineer quantum states using a beam splitter, homodyne detection, and a squeezed vacuum as an ancillar state. This scheme is efficient in producing non-Gaussian quantum states such as squeezed single photons and superpositions of coherent states (SCSs). We show that a SCS with well defined parity and high fidelity can be generated from a Fock state of n≤4, and conjecture that this can be generalized for an arbitrary n Fock state. We describe...[Show more]
