Cari amici, We were only able to get through half of the material in this week's seminar on quantum error correction, so we'll pick it up again next Wednesday, 17.4, at 15:30-16:30 in D1.14 (afternoon this time to accommodate a listener across the Atlantic). I'll go through the stabilizer formalism and show a few examples of codes currently in use in today's quantum computers. Join us in person or online at https://meet.jit.si/CQISeminarTalks Warmly, Will Title: Quantum error correction 101, continued Outline: * Stabilizer formalism * CSS codes (ex. [[7,1,3]] Steane code) * Surface codes (ex. [[25,1,5]] Toric code) * Color codes (ex. [[8,3,2]] Cubic code) * LDPC codes
