High-fidelity continuous-variable quantum teleportation toward multi-step quantum operations
Mitsuyoshi Yukawa, Hugo Benichi, Akira Furusawa
The progress in quantum operations of continuous-variable (CV) schemes can be reduced to that in CV quantum teleportation. The fidelity of quantum teleportation of an optical setup…
Sequential Quantum Teleportation of Optical Coherent States
Hidehiro Yonezawa, Akira Furusawa, Peter van Loock
We demonstrate a sequence of two quantum teleportations of optical coherent states, combining two high-fidelity teleporters for continuous variables. In our experiment, the individ…
Experimental demonstration of quantum teleportation of broadband squeezing
Hidehiro Yonezawa, Samuel L. Braunstein, Akira Furusawa
We demonstrate an unconditional high-fidelity teleporter capable of preserving the broadband entanglement in an optical squeezed state. In particular, we teleport a squeezed state…
Observation of -9 dB quadrature squeezing with improvement of phase stability in homodyne measurement
Yuishi Takeno, Mitsuyoshi Yukawa, Hidehiro Yonezawa +1
We observe -9.010.14 dB of squeezing and +15.120.14 dB of antisqueezing with a local oscillator phase locked in homodyne measurement. In reference [1], two main factors a…
Demonstration of deterministic and high fidelity squeezing of quantum information
Jun-ichi Yoshikawa, Toshiki Hayashi, Takayuki Akiyama +4
By employing at recent proposal (R. Filip, P. Marek and U.L. Andersen, Phys. Rev. A {\bf 71}, 042308 (2005) \cite{Filip05.pra}), we experimentally demonstrate a universal, determin…
