Abstract: A system for coupling a qubit to a register, wherein the system controls application of a protocol comprising a sequence of pulses synchronized with an RF field, the protocol further comprising a timing, a phase, and a duration of each of the pulses comprising a single qubit gate, a period and amplitude of the RF field, and a number of repeats of the sequence, so that application of the protocol controls a coherent spin exchange interaction between a register and a qubit having a zero magnetic dipole moment. The qubit comprises a first spin state and a second spin state both of which have a zero magnetic dipole moment; the register comprises multiple register spins having an energy level structure; and the register spins are indistinguishable so as to be configurable in basis states including a superposition state used for storing the quantum state of the qubit.
