Loss-insensitive quantum noise reduction in a Raman amplifier with coherent feedback
Jianmin Wang, Rong Zhu, Z. Y. Ou
A quantum amplifier usually adds extra noise inevitably through coupling to internal degrees of freedom while amplifying the signal. The introduction of quantum correlations can ef…
SU(2)-in-SU(1,1) Nested Interferometer for Highly Sensitive, Loss-Tolerant Quantum Metrology
Wei Du, Jia Kong, Jun Jia +6
We present experimental and theoretical results on a new interferometer topology that nests a SU(2) interferometer, e.g., a Mach-Zehnder or Michelson interferometer, inside a SU(1,…
Intramode correlations enhanced phase sensitivities in an SU(1,1) interferometer
Qian-Kun Gong, Dong Li, Chun-Hua Yuan +2
We theoretically derive the lower and upper bounds of quantum Fisher information (QFI) of an SU(1,1) interferometer whatever the input state chosen. According to the QFI, the cruci…
The phase sensitivity of an SU(1,1) interferometer with homodyne detection
Dong Li, Chun-Hua Yuan, Z. Y. Ou +1
We theoretically study the phase sensitivity of the SU(1,1) interferometer with a coherent light together with a squeezed vacuum input case using the method of homodyne. We find th…
Observation of Nonclassical Photon Statistics due to Quantum Interference
Y. J. Lu, Z. Y. Ou
The nonclassical effect of photon anti-bunching is observed in the mixed field of a narrow band two-photon source and a coherent field under certain condition. A variety of differe…
