Threshold Theorems

This lecture covers threshold theorems in quantum error correction codes, discussing the relationship between physical error rates, logical error rates, and the code properties. It explores various ways to achieve a 2-qubit error rate and the importance of characterizing the code. The instructor explains the concept of transversal gates and the significance of error propagation in quantum error correction. The lecture also delves into the Eastin-Knill theorem and the preparation of magic states for fault-tolerant quantum computation.
