Query: Transfer of single photon polarization states by two-channel continuous
  variable teleportation   Superpositions of two orthogonal single-photon polarization states are
commonly used as optical qubits. If such qubits are sent by continuous variable
quantum teleportation, the modifications of the qubit states due to imperfect
entanglement cause an increase in the average photon number of the output
state. This effect can be interpreted as an accidental quantum cloning of the
single photon input. We analyze the output statistics of the single photon
teleportation and derive the transfer and cloning fidelities from the equations
of the polarization qubit.
