Quantum Readout and Fast Initialization of Nuclear Spin Qubits with Electric Currents
Quantum Readout and Fast Initialization of Nuclear Spin Qubits with Electric Currents
Nuclear spin qubits have the longest coherence times in the solid state, but their quantum read-out and initialization is a great challenge. We present a theory for the interaction of an electric current with the nuclear spins of donor impurities in semiconductors. The theory yields a sensitivity criterion for quantum …
