Practical quantum error correction with the XZZX code and Kerr-cat qubits

Dr Ben Brown
University of Sydney

Abstract
In this talk, Dr. Brown discusses how to decode quantum codes using symmetries and conservation laws. He then gives an overview of the XZZX surface code and its high performance against biased noise before showing how to produce and preserve noise biases with Kerr-cat qubits. He concludes with the threshold error rates that result from concatenating Kerr-cat qubits with the XZZX surface code.
