Once we have initialized our qubits, they won’t start doing these ground-breaking quantum computations for us by themselves! For this, we need to be able to manipulate them using classical, non-quantum systems. In this set of videos, Dr. Fabio Sebastiano will discuss this classical interface with our quantum system, in specific for a spin qubit. This interface is the layer closest to the actual qubits. Do you remember the particular properties of these spin qubits? With the knowledge you have about them, what do you think this quantum-classic interface would look like? Can you predict some of the problems which will arise?

Prerequisite knowledge

• None

Further thinking

Assembling both classical and quantum circuits becomes an important task in a real-life quantum computer. In the video Sebastiano refers to wiring and the cooling power of the fridges as some of the biggest problems. Taking these issues into consideration and the previous lecturea, can you think of the electronic requirements for a spin qubit controller?
