Selective excitation of multipolar spoof plasmons using orbital angular momentum of light
Takashi Arikawa, Tomoki Hiraoka, Shohei Morimoto +7
The nature of light-matter interaction is governed by the spatial-temporal structures of a light field and material wavefunctions. The emergence of the light beam with transverse p…
Beating the standard quantum limit: Phase super-sensitivity of N-photon interferometers
Ryo Okamoto, Holger F. Hofmann, Tomohisa Nagata +3
Quantum metrology promises greater sensitivity for optical phase measurements than could ever be achieved classically. Here we present a theory of the phase sensitivity for the gen…
Beating the Standard Quantum Limit with Four Entangled Photons
Tomohisa Nagata, Ryo Okamoto, Jeremy L. O'Brien +2
Precision measurements are important across all fields of science. In particular, optical phase measurements can be used to measure distance, position, displacement, acceleration a…
Heralded single photon source at 1550 nm from pulsed parametric down conversion
Alexandre Soujaeff, Shigeki Takeuchi, Keiji Sasaki +2
Heralding of single photon at 1550 nm from pump pulsed non degenerate spontaneous parametric downconversion is demonstrated. P(1) and P(2) of our source are 0.1871 and 2.4 x 10 ^-3…
Determining the optical axes of entangled Laguerre Gauss modes
Daisuke Kawase, Shigeki Takeuchi, Keiji Sasaki +3
A method for determining the positions of hologram dislocations relative to the optical axes of entangled Laguerre Gaussian modes is proposed. In our method, the coincidence count…
Demonstration of an optical quantum controlled-NOT gate without path interference
Ryo Okamoto, Holger F. Hofmann, Shigeki Takeuchi +1
We report the first experimental demonstration of an optical quantum controlled-NOT gate without any path interference, where the two interacting path interferometers of the origin…
