Using subdiffracted light from a nanoplasmonic resonator we demonstrate hot-spot nanoheating control of quantum operations at elevated temperatures via temperature-induced shifts of the transition energies of the individual qubits in and out of resonance with the near-field. This introduces a dynamical switch for optical quantum control, significantly elevating solid-state quantum information processing technologies towards higher temperatures.
Investigating the Moiré and Seebeck-Peltier effects in thin-film black phosphorous under excitation from a near-field plasmonic resonator we demonstrate the ability to directionally steer electrical current and adeptly manipulate temperature on the nanoscale.
