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…
Effects of noisy entangled state transmission on quantum teleportation
Holger F. Hofmann, Kenji Tsujino, Shigeki Takeuchi
Quantum teleportation requires the transmission of entangled pairs to Alice and Bob. Transmission errors modify the entangled state before the teleportation can be performed. We de…
Quantum phase gate for photonic qubits using only beam splitters and post-selection
Holger F. Hofmann, Shigeki Takeuchi
We show that a beam splitter of reflectivity one-third can be used to realize a quantum phase gate operation if only the outputs conserving the number of photons on each side are p…
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…
Quantum filter for non-local polarization properties of photonic qubits
Holger F. Hofmann, Shigeki Takeuchi
We present an optical filter that transmits photon pairs only if they share the same horizontal or vertical polarization, without decreasing the quantum coherence between these two…
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…
