Recently, some approaches for connecting few-qubit subsystems into large-scale circuits have been suggested. These studies suggest the schemes which benefit from short range interactions for local coupling and long range interactions for nonlocal coupling, might be an effective way toward large scale quantum computation and long distant quantum communication.
So far, we have focused on single NV center coupling with 13C in diamond and showed good controllability of spins for quantum information processing. The NV center has been interested as few qubit subsystem in the above schemes. In this project, we would like to develop the number of qubits of the subsystem and techniques toward the interaction between subsystems. For local coupling, we would like to develop by using the coupling between nuclear spin and electron spin. For long range interaction, we would like to develop by using the coupling among electron spins.
