High purity bright single photon source
J. S. Neergaard-Nielsen, B. Melholt Nielsen, H. Takahashi +2
Using cavity-enhanced non-degenerate parametric downconversion, we have built a frequency tunable source of heralded single photons with a narrow bandwidth of 8 MHz, making it comp…
Time domain Einstein-Podolsky-Rosen correlation
Nobuyuki Takei, Noriyuki Lee, Daiki Moriyama +2
We experimentally demonstrate creation and characterization of Einstein-Podolsky-Rosen (EPR) correlation between optical beams in the time domain. The correlated beams are created…
Generation of a superposition of odd photon number states for quantum information networks
J. S. Neergaard-Nielsen, B. Melholt Nielsen, C. Hettich +2
We report on the experimental observation of quantum-network-compatible light described by a non-positive Wigner function. The state is generated by photon subtraction from a squee…
