Quantum Teleportation of Superposition State for Squeezed States
Xin-Hua Cai, Le-Man Kuang
abstract: This paper proposes a scheme for teleporting an arbitrary coherent
superposition state of two equal-amplitude and opposite-phase squeezed vacuum
states (SVS) via a symmetric 50/50 beam splitter and photodetectors. It is
shown that the quantum teleportation scheme has the successful probability 1/4.
Maximally entangled SVS's are used as quantum channel for realizing the
teleportation scheme. It is shown that if an initial quantum channel is in a
pure but not maximally entangled SVS, the quantum channel may be distilled to a
maximally entangled SVS through entanglement concentration.
