So far we have seen the single qubit gates and their representation on the Bloch sphere, but how can we actually implement them on a spin qubit? That is done by applying a microwave signal electrically. Fabio Sebastiano (QuTech) guides us through the requirements of this microwave pulse and shows how accurate those need to be to perform a single qubit gate. He also gives us an overview of how to apply it to a many-qubit system using today’s technology.
How can you apply single-qubit gates in spin qubits?
What determines the axis of rotation of the qubit in the Bloch sphere when applying a microwave signal?
