    Optically controlled quantum gates for three spin qubits in quantum dot–microcavity coupled systems

    We investigate theoretically the possibility of achieving feasible solid-state quantum computing by compactly constructing a set of two or three quantum gates on stationary electron spin qubits, including the ...

    Influence of the flip–flop interaction on a single plasmon transport in 1D waveguide

    Transport of a single plasmon in the 1D waveguide coupled to two emitters with the flip–flop interaction is discussed theoretically via the real-space approach. We showed that the transmission and reflection o...
