Abstract

An alternative voltage-controlled scheme is proposed for the generation of an N-qubit W state with distant self-assembled semiconductor quantum dot molecules (QDMs) via adiabatic-varying tunnel coupling. The N semiconductor QDMs are trapped in N spatially separated cavities coupled with N1 fibers. The present scheme takes full advantage of adiabatic passage and the exceptional features of semiconductor QDMs. The decoherence caused by the excited state spontaneous emission and the fiber loss was efficiently suppressed. In addition, our calculations show that the present scheme is robust against the deviation of the parameters.
