Description
Donor spins in silicon have been shown to have good single qubit properties but their scalability is still limited by the lack of convenient coupling and readout methods. One possibility to solve these issues would be to couple the spins to mechanical modes, which can then be used as both a coupling pathway between the qubits and a readout bus to optical telecom range photons, taking advantage of the methods of cavity optomechanics. I’ll discuss our work in coupling donor spins in silicon to both MHz frequency and GHz frequency mechanical modes.
