Collective effects of multi-scatterer on coherent propagation of photon in a two dimensional network

D. Z. Xu, Yong Li, C. P. Sun +1

We study the collective phenomenon in the scattering of a single-photon by one or two layers of two-level atoms. By modeling the photon dispersion with a two-dimensional (2D) coupl…

Exact Non-Markovian Master Equation and Dispersive Probing of Non-Markovian Process

Li-Ping Yang, C. Y. Cai, D. Z. Xu +2

For a bosonic (fermionic) open system in a bath with many bosons (fermions) modes, we derive the exact non-Markovian master equation in which the memory effect of the bath is refle…

Photon blockade induced by atoms with Rydberg coupling

Jin-Feng Huang, Jie-Qiao Liao, C. P. Sun

We study the photon blockade of two-photon scattering in a one-dimensional waveguide, which contains two atoms coupled via the Rydberg interaction. We obtain the analytic scatterin…

Anomalous decoherence in a dissipative two-level system

Hai-Bin Liu, Jun-Hong An, Chong Chen +3

We study systematically the non-Markovian decoherence dynamics of a dissipative two-level system, i.e., the so-called spin-boson model. It is interesting to find that the decoheren…

Parity Measurement is Sufficient for Phase Estimation at the Quantum Cramer-Rao Bound for Path-Symmetric States

Sejong Kim, Kaushik P. Seshadreesan, Jonathan P. Dowling +1

In this letter, we show that for all the so-called path-symmetric states, the measurement of parity of photon number at the output of an optical interferometer achieves maximal pha…
