The non-deterministic quantum logic operation and teleportation of a
vacuum and single photon superposition state via parametric amplifiers
Xu-Bo Zou, K. Pahlke, W. Mathis
abstract: We firstly present an all-optical scheme to implement the non-deterministic
quantum logic operation of Knill, Laflamme and Milburn (Nature, 409,
46-52(2001)). In our scheme, squeezed vacuum state is acted as auxiliary state
instead of single photon resources. Then we demonstrate that same setup can be
used to teleport a superposition of vacuum and single photon state of the form
$\alpha|0>+\beta|1>$ and a superposition of vacuum and single polarized photon
state of the form $\alpha|0>+\beta|H>+\gamma|V>$.
