| Outline of Research at the Start |
In this project, an on-chip nuclear spin qubit platform with long coherence time and direct compatibility with telecommunication photons will be developed based on individual isotope-purified 167Er3+ ions doped in crystal host materials integrated on Si substrate, in order to implement single ion based quantum repeaters in the telecommunication band. First, single 167Er3+ ions will be optically addressed by using photonic crystal nanocavities. Then, initialization, control and readout quantum states of individual 167Er3+ nuclear spin qubits will be demonstrated.
