Title: Ultrafast control of nuclear spins using only microwave pulses: Towards switchable solid-state quantum gates

Abstract

We demonstrate the control of the {alpha}-proton nuclear spin, I =1/2, coupled to the stable radical {center_dot}CH(COOH){sub 2}, S =1/2, in a {gamma}-irradiated malonic acid single crystal using only microwave pulses. We show that, depending on the state of the electron spin (m{sub S}={+-}1/2), the nuclear spin can be locked in a desired state or oscillate between m{sub I}=+1/2 and m{sub I}=-1/2 on the nanosecond time scale. This approach provides a fast way of controlling nuclear spin qubits and also enables the design of switchable spin-based quantum gates by addressing only the electron spin.
