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…

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…

Optimal Storage and Retrieval of Single-Photon Waveforms
Shuyu Zhou, Shanchao Zhang, Chang Liu +5
We report an experimental demonstration of optimal storage and retrieval of heralded single-photon wave packets using electromagnetically induced transparency (EIT) in cold atoms a…
