We propose a deterministic yet fully passive scheme to transfer the quantum state from frequency-encoded photon spin of dot mediated by nanophotonic waveguide. assess quality studying effects all relevant experimental imperfections on state-transfer fidelity. show that fidelity exceeding $95%$ is achievable for experimentally realistic parameters.

We investigate the electronic transport through a single-level quantum-dot which is capacitively coupled to a charge-qubit. By employing the method of nonequilibrium Green's functions, we calculate the electric current through quantum dot at finite bias voltages. The Green's functions and self-energies of the system are calculated perturbatively and self-consistently to the second order of inte...

We present a waveguide-coupled photonic crystal H1 cavity structure in which the orthogonal dipole modes couple to spatially separated photonic crystal waveguides. Coupling of each cavity mode to its respective waveguide with equal efficiency is achieved by adjusting the position and orientation of the waveguides. The behavior of the optimized device is experimentally verified for where the cav...

Integrated quantum photonic devices with single quantum dot emitters A. Mark Fox University of Sheffield The integration of semiconductornanostructures with on-chip photonic devices offers the possibility to incorporate quantum-dot (QD) single-photon sources into advanced quantum-optical circuits. In order achieve this goal, a number of key photonic components have to be developed in a platform...

In this paper we consider electromagnetic field quantization in the presence of a dispersive and absorbing semiconductor quantum dot. By using macroscopic approach and Green's function method, quantization of electromagnetic field is investigated. Interaction of a two-level atom , which is doped in a semiconductor quantum dot, with the quantized field is considered and its spontaneous emission ...
