Day 790: Error Model and Distance

Learning Objectives

• •**Describe** X, Z, and Y errors in terms of stabilizer violations
• •**Visualize** errors as creating pairs of anyonic excitations
• •**Define** the code distance as minimum non-trivial loop length
• •**Explain** the error correction process and minimum-weight decoding
• •**State** the error threshold (~10.9%) for independent noise
• •**Compare** toric code performance with other quantum codes
