SUMMARY:Introduction to Quantum Error-Correcting Codes
DESCRIPTION:Quantum computers hold the promise of achieving extraordinary power, from solving complex mathematical problems to simulating nature on a scale far beyond the reach of any classical device. However, a major obstacle to realizing this potential is decoherence, which causes the decay of fragile quantum information through interactions with the surrounding environment. The theory of quantum error-correcting codes (QECC) shows that building a fault-tolerant quantum computer is possible, despite practical infeasibility of creating perfectly working physical qubits.In this talk, I will provide an introduction to the theory of QECC, motivating its structure through simple examples and highlighting its intimate connection to quantum entanglement. I will introduce the stabilizer formalism and use it to describe the toric code, which is a foundational model for topological codes and represents one of the leading contemporary proposals for realizing a fault-tolerant quantum computer.
