No postselection is required, meaning that the quantum state transfer happens deterministically. Decoherence of the charge qubit causes a non-monotonic decay of the fidelity of the transferred state with increasing decoherence rate.3 pages, 3 figuresMesoscale and Nanoscale PhysicsQuantum Physicstext
