Operations on the Transmon Qubit - Circuit QED

For superconducting, or transmon qubits, we bring a multi-level system back to an artificial quantum two-level system. However, merely having this two-level system is, of course, not enough! In this video, professor Leo DiCarlo will elaborate on the main operations on the transmon qubits: qubit readout and two-qubit gates.

After this, he will discuss the resulting architecture, combining the qubits and transmission-line resonators used and illustrate the concept with several examples from recent research.

Prerequisite knowledge

Further Thinking

At the end of the video, professor DiCarlo teases us with a new design for the third-generation of quantum processors, with the top priority to scale up to a hundred qubits. Before diving into this video, what requirements do you think these processors should have?
