Deterministic Remote Preparation of Electrons States in Coupled Quantum Dots by Stimulated Raman Adiabatic Passage

We present a proposal for deterministic remote preparation of electrons states in a semiconductor nanostructure consisting of a single and a double quantum dot. We show that deterministic remote preparation requires a minimum of only one controlled-Not gate plus one Hadamard gate for the basis transformation, and one Hadamard gate and one single-spin rotation for the reconstruction procedure. Picosecond-scale pulses allow for ultra-short total duration of the protocol, which implies a high remote preparation fidelity.
