Proposal for optical parity state re-encoder
Y. X. Gong, A. J. F. Hayes, G. C. Guo +1
We propose a re-encoder to generate a refreshed parity encoded state from an existing parity encoded state. This is the simplest case of the scheme by Gilchrist et al. (Phys. Rev.…
Experimental demonstration of phase measurement precision beating standard quantum limit by projection measurement
F. W. Sun, B. H. Liu, Y. X. Gong +3
We propose and demonstrate experimentally a projection scheme to measure the quantum phase with a precision beating the standard quantum limit. The initial input state is a twin Fo…
Demonstration of Temporal Distinguishability of Three and Four Photons with Asymmetric Beam Splitter
Z. Y. Ou, B. H. Liu, F. W. Sun +3
By using an asymmetric beam splitter, we observe the generalized Hong-Ou-Mandel effects for three and four photons, respectively. Furthermore, we can use this generalized Hong-Ou-M…
Stimulated emission of two photons in parametric amplification and its interpretation as multi-photon interference
F. W. Sun, B. H. Liu, Y. X. Gong +3
Stimulated emission of two photons is observed experimentally in the parametric amplification process and is compared to a three-photon interference scheme. We find that the underl…
