Microwave drivers for qubits

How can you apply single-qubit gates in spin qubits?

There are several ways of applying single qubit gates to spin qubits:

  • You can move the electron in a magnetic field gradient.
  • You can apply a current in order to generate an AC magnetic field.
  • You can send microwave signals matching the Larmor frequency of the qubit.

What determines the axis of rotation of the qubit in the Bloch sphere when applying a microwave signal?
The phase of the signal.
