Quantum Error Correction | Understanding Quantum Information & Computation | Lesson 15

This is part of the Understanding Quantum Information & Computation series. Watch the full playlist here:    • Understanding Quantum Information & Comput...   This Understanding Quantum Information and Computation lesson focuses on more sophisticated quantum error correcting code constructions than the examples presented in previous lessons, including codes that can tolerate a relatively high error rate and that are viewed as promising candidates for practical quantum error correction. In particular, the lesson begins with a general class of quantum error correcting codes known as CSS codes, then moves on to an important quantum error correcting code known as the toric code, and concludes with a brief discussion surface codes and color codes. 0:00 – Introduction 1:22 – Overview 2:30 – Classical linear codes 9:31 – CSS codes 14:14 – Error detection and correction 17:47 – Code spaces of CSS codes 22:20 – Toric code 30:05 – Errors and syndromes 38:31 – Correcting errors 40:30 – Other code families 46:04 – Conclusion Find the written content for this lesson on IBM Quantum Learning: https://learning.quantum.ibm.com/cour...
