Error Propagation and Threshold

Dr. Simon Devitt rejoins us to describe how errors propagate in a system and what a quantum error correction threshold is.

Dr. Simon Devitt of Turing, Inc. rejoins us to describe how errors propagate inside a quantum system, and how that leads us to determine a threshold for a quantum error correction code. When the probability of error on a single gate is above that threshold, error correction makes things worse instead of better. When the probability of error is below the threshold, the overall quality of our system begins to improve.
