title: Charge qubit entanglement via conditional single-electron transfer in an array of quantum dots.
abstract: We propose a novel scheme to generate entanglement among quantum-dot-based charge qubits via sequential electron transfer in an auxiliary quantum dot structure whose transport properties are conditioned by qubit states. The transfer protocol requires the utilization of resonant optical pulses combined with an appropriate voltage gate pattern. As an example illustrating the application of this scheme, we examine the nine-qubit Shor code state preparation together with the error syndrome measurement.
