The Certainty Principle: Correcting Errors in Quantum Computers

Abstract:
Quantum algorithms that involve a large number of qubits (between thousands and millions) play a pivotal role in advancing quantum computing, unlocking the ability to tackle intricate problems that are beyond the reach of classical computers. However, noise in quantum systems represents a significant hurdle, making it challenging to maintain the integrity of quantum computation, especially when the number of qubits scales. In this talk I will provide an accessible introduction to quantum error correction, and I will illustrate some of the latest methodologies for overcoming quantum errors using specialized decoding algorithms. The talk will consider decoders for the current state-of-the-art quantum error correcting codes as well as for more powerful potential future coding solutions. We will see that the decoding methods used for error correction in systems such as WiFi are not sufficient for quantum codes and that new innovative solutions are required to be put forward.
