In the next two video lectures, Fabio will talk about the layer that is closest to the qubits: the quantum-to-classical interface. How do we realise the readout of qubits and what are the associated challenges?

Main takeaways

• In order to control the qubits of the quantum processor, we need an electronic interface to perform the operations on the qubits and read out the states of the qubits.
• Custom-built electronic components built to operate at cryogenic temperatures are needed to build a scalable quantum computer.
• The components of the electronic interface need to be placed as close as possible to the quantum processor.
• To make it possible to build a scalable quantum computer we need to take performance, power dissipation, and cryogenic operation into account when building the electronic interface.
