Superconducting circuits, Hamiltonian engineering of qubits and the Kerr-cat metapotential

September 9, 2021 • 10:00 AM EDT

In this talk, we will give an introduction to the world of quantum superconducting circuits.

We will discuss how the commercial availability of key technologies including robust cryogenic environments enable the exploration of quantum computation with circuits. In particular, we will focus on efforts performed at Yale on the so-called Kerr-cat qubit which presents clear advantages over similar superconducting qubits and, importantly, requires only minor conceptual modifications of the prototypical setup.

We will take this example as an illustration of the new avenues that Hamiltonian engineering can open and the technical challenges that one must face as more microwave lines and more pumps are required in the cryostat. Register here.
