Absolute sensitivity of phase measurement in an SU(1,1) type interferometer
Wei Du, Jun Jia, J. F. Chen +2
Absolute sensitivity is measured for the phase measurement in an SU(1,1) type interferometer and the results are compared to that of a Mach-Zehnder interferometer operated under th…
Frequency down-conversion for a quantum network
Yu Ding, Z. Y. Ou
By using parametric down-conversion process with a strong signal field injection, we demonstrate coherent frequency down-conversion from a pump photon to an idler photon. Contrary…
Observation of Rabi oscillation of light assisted by atomic spin wave
L. Q. Chen, Guo-Wan Zhang, Cheng-ling Bian +3
Coherent conversion between a Raman pump field and its Stokes field is observed in a Raman process with a strong atomic spin wave initially prepared by another Raman process operat…
Observation of single- and two-photon beating between independent Raman scattering
Li-Qing Chen, Cheng-ling Bian, Guo-Wan Zhang +2
By using spontaneous Raman processes in the high gain regime, we produce two independent Raman Stokes fields from an atomic ensemble. Temporal beating is observed between the two d…
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 three-photon de Broglie wavelength by projection measurement
B. H. Liu, F. W. Sun, Y. X. Gong +3
Two schemes of projection measurement are realized experimentally to demonstrate the de Broglie wavelength of three photons without the need for a maximally entangled three-photon…
