Entanglement-enhanced optical magnetometry beyond the standard quantum limit
Jun Jia, Túlio Brito Brasil, Maimouna Bocoum +6
Optical atomic magnetometry is a powerful tool for continuous sensing applications, yet, in the absence of quantum correlations, its sensitivity is limited by the standard quantum…
Hybrid quantum network for sensing in the acoustic frequency range
Valeriy Novikov, Jun Jia, Túlio Brito Brasil +6
Ultimate limits for sensing of fields and forces are set by the quantum noise of a sensor. Entanglement allows for suppression of such noise and for achieving sensitivity beyond st…
Acoustic frequency atomic spin oscillator in the quantum regime
Jun Jia, Valeriy Novikov, Tulio Brito Brasil +3
We experimentally demonstrate quantum behavior of a macroscopic atomic spin oscillator in the acoustic frequency range. Quantum back-action of the spin measurement, ponderomotive s…
Arbitrary cylindrical vector beam generation enabled by polarization-selective Gouy phase shifter
J. Jia, K. Zhang, G. Hu +7
Cylindrical vector beams (CVBs), which possesses polarization distribution of rotational symmetry on the transverse plane, can be developed in many optical technologies. Convention…
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,…
Quantum dense metrology by an SU(2)-in-SU(1,1) nested interferometer
Wei Du, J. F. Chen, Z. Y. Ou +1
With the help of quantum entanglement, quantum dense metrology (QDM) is a technique that can perform the joint estimates of two conjugate quantities such as phase and amplitude mod…
A novel two-mode squeezed light based on double-pump phase-matching
Xuan-Jian He, Jun Jia, Gao-Feng Jiao +3
A novel two-mode non-degenerate squeezed light is generated based on a four-wave mixing (4WM) process driven by two pump fields crossing at a small angle. By exchanging the roles o…
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…
