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…
Entanglement and interference between different degrees of freedom of photons states
F. W. Sun, B. H. Liu, Y. F. Huang +3
In this paper, photonic entanglement and interference are described and analyzed with the language of quantum information process. Correspondingly, a photon state involving several…
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…
Structuring quantum effects: superoperators as arrows
J. K. Vizzotto, T. Altenkirch, A. Sabry
We show that the model of quantum computation based on density matrices and superoperators can be decomposed in a pure classical (functional) part and an effectful part modeling pr…
