Accidental cloning of a single-photon qubit in two-channel continuous-variable quantum teleportation
Toshiki Ide, Holger F. Hofmann
The information encoded in the polarization of a single photon can be transferred to a remote location by two-channel continuous-variable quantum teleportation. However, the finite…
Optimal cloning of single photon polarization by coherent feedback of beam splitter losses
Holger F. Hofmann, Toshiki Ide
Light fields can be amplified by measuring the field amplitude reflected at a beam splitter of reflectivity R and adding a coherent amplitude proportional to the measurement result…
Transfer of single photon polarization states by two-channel continuous variable teleportation
Toshiki Ide, Holger F. Hofmann
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 mo…
Continuous variable teleportation of single photon states (Proceedings version)
Toshiki Ide, Holger F. Hofmann, Takayoshi Kobayashi +1
We investigate the changes to a single photon state caused by the non-maximal entanglement in continuous variable quantum teleportation. It is shown that the teleportation measurem…
Gain tuning and fidelity in continuous variable quantum teleportation
Toshiki Ide, Holger F. Hofmann, Akira Furusawa +1
The fidelity of continuous variable teleportation can be optimized by changing the gain in the modulation of the output field. We discuss the gain dependence of fidelity for cohere…
Information extraction and quantum state distortions in continuous variable quantum teleportation
Holger F. Hofmann, Toshiki Ide, Takayoshi Kobayashi +1
We analyze the loss of fidelity in continuous variable teleportation due to non-maximal entanglement. It is shown that the quantum state distortions correspond to the measurement b…
