Carbon Nanotube Qubit Devices
Abstract Regular

Radio-frequency reflectometry readout provides fast non invasive read out of spin qubits hosted in suspended carbon nanotube qubits devices. These suspended carbon nanotube devices have increased qubit coherence time due to the spatial separation of the qubits, hosted in double quantum dots defined by gate electrodes close to the carbon nanotube, and charge noise which is a major source of decoherence. Micromagnet arrays, when magnetised by a vector magnet, situated close to the carbon nanotube break spin degeneracy to allow for spin qubit hosting in the double quantum dots.
