Quantum Reductive Perturbation Method for Photon Propagations in a Cold Atomic Gas
Ou Yao, Huang Guoxiang
We develop a quantum reductive perturbation method (RPM), a generalization of classical RPM widely used in nonlinear wave theory, to derive a simplified model (i.e. quantum nonline…

Switch and Phase Shift of Photon Polarization Qubits via Double Rydberg Electromagnetically Induced Transparency
Ou Yao, Huang Guoxiang
We propose and analyze a scheme for manipulating the propagation of single photon pulses with two polarization components in a Rydberg atomic gas via double electromagnetically ind…
