Efficient routing of single photons by one atom and a microtoroidal cavity
Takao Aoki, A. S. Parkins, D. J. Alton +5
Single photons from a coherent input are efficiently redirected to a separate output by way of a fiber-coupled microtoroidal cavity interacting with individual Cesium atoms. By ope…
Quantum error correction beyond qubits
Takao Aoki, Go Takahashi, Tadashi Kajiya +4
Quantum computation and communication rely on the ability to manipulate quantum states robustly and with high fidelity. Thus, some form of error correction is needed to protect fra…
Generation of continuous-wave broadband Einstein-Podolsky-Rosen beams using periodically-poled lithium niobate waveguides
Ken-ichiroh Yoshino, Takao Aoki, Akira Furusawa
Continuous-wave light beams with broadband Einstein-Podolsky-Rosen correlation (Einstein-Podolsky-Rosen beams) are created with two independent squeezed vacua generated by two peri…
Squeezing at 946nm with periodically-poled KTiOPO_4
Takao Aoki, Go Takahashi, Akira Furusawa
We report generation of squeezed vacuum in sideband modes of continuous-wave light at 946 nm using a periodically poled KTiOPO_4 crystal in an optical parametric oscillator. At the…
Demonstration of quantum telecloning of optical coherent states
Satoshi Koike, Hiroki Takahashi, Hidehiro Yonezawa +4
Quantum cryptography promises in-principle secure communication between two parties via a quantum channel, with the ability to discover eavesdropping when it occurs. In 1999, a tel…
High-fidelity teleportation beyond the no-cloning limit and entanglement swapping for continuous variables
Nobuyuki Takei, Hidehiro Yonezawa, Takao Aoki +1
We experimentally demonstrate continuous-variable quantum teleportation beyond the no-cloning limit. We teleport a coherent state and achieve the fidelity of 0.700.02 that sur…
