Course 4 in IBM’s Understanding Quantum Information and Computation series. The same material as the later Watrous video lectures already listed under Understanding Quantum Information and Computation, delivered here as a standalone Learning course with an exam.
The overview covers what a quantum error-correcting code is, discretisation of errors, the stabilizer formalism, Calderbank-Shor-Steane (CSS) codes, the toric code and surface codes, and fault-tolerant computation on encoded information. IBM lists 15 hours. The intended audience is students and professionals in CS, physics, engineering or maths who want the theory, not a hardware lab.
Google’s Hands-On Quantum Error Correction is the applied Cirq counterpart. This one is the Watrous theory course.
Who it is for
People who finished Fundamentals of Quantum Algorithms and want the error-correction chapter, not a first Qiskit lesson.
