A high-yield single photon source using gated spontaneous parametric down conversion
Shigeki Takeuchi, Ryo Okamoto, Keiji Sasaki
The construction of a single photon source using gated parametric fluorescence is reported with the measurement results of the photon number distribution. A beamlike twin-photon me…
Efficiencies for the single mode operation of a quantum optical nonlinear shift gate
Kunihiro Kojima, Holger F. Hofmann, Shigeki Takeuchi +1
We investigate the single mode operation of a quantum optical nonlinear πphase shift gate implemented by a single two-level atom in one-dimensional free space. Since the single mod…
A study on the shape of two-photon wavefunctions after the nonlinear interaction with a one-dimensional atom
Kunihiro Kojima, Holger F. Hofmann, Shigeki Takeuchi +1
We study the interaction of Gaussian one- and two-photon pulses with a single two-level atom based on a one-dimensional model of pulse propagation to and from the atom. The charact…
