Abstract
Systems and methods are provided for implementing arbitrary single-qubit quantum gates using sequences of single-qubit quantum gates. The systems and methods can implement a first quantum gate in a gate sequence by applying a first sequence of phase-shifted pulses to the qubit. After applying the first quantum gate, a second quantum gate in the gate sequence can be implemented by applying a second sequence of phase-shifted pulses to the qubit. The implementation of the second quantum gate can introduce an additional rotation. This additional rotation can be independent of the implementation of the first quantum gate. A pulse in the second sequence can be configured to implement: a virtual Z gate having a first rotation angle; an X gate having a second rotation angle; and the virtual Z gate having a negative of the first rotation angle.
