Fully tuneable, Purcell-enhanced solid-state quantum emitters

Multi-photon processes in solid-state quantum emitters

In order to stimulate these systems into emitting photons, lasers are used to excite them to high-level excited states. These states relax, and in doing so release photons. This is called quasi-resonant excitation. The problem with this quasi-resonant excitation procedure is that it also excites the semiconductor solid-state environment surrounding the quantum dot. This can couple to the quantu...

Interfacing quantum-optical and solid-state qubits.

We present a generic model of coupling quantum-optical and solid-state qubits, and the corresponding transfer protocols. The example discussed is a trapped ion coupled to a charge qubit (e.g., Cooper pair box). To enhance the coupling and to achieve compatibility between the different experimental setups we introduce a superconducting cavity as the connecting element.

On the quantum master equation for fermions

A quantum master equation is obtained for identical fermions by including a relaxation term in addition to the mean-field Hamiltonian. [Huang C F and Huang K N 2004 Chinese J. Phys. 42 221; Gebauer R and Car R 2004 Phys. Rev. B 7
