Fast Spin-Orbit Qubit in an Indium Antimonide Nanowire
Fast Spin-Orbit Qubit in an Indium Antimonide Nanowire
Due to the strong spin-orbit interaction in indium antimonide, orbital motion and spin are no longer separated. This enables fast manipulation of qubit states by means of microwave electric fields. We report Rabi oscillation frequencies exceeding 100 MHz for spin-orbit qubits in InSb nanowires. Individual qubits can be selectively addressed …
