Quantum Error Correction: Noise-Adapted Techniques and Applications

The quantum computing devices of today have tens to hundreds qubits that are highly susceptible noise due unwanted interactions with their environment. theory error correction provides a scheme by which the effects such on states can be mitigated, paving way for realising robust, scalable computers. In this article we survey current landscape correcting (QEC) codes, focusing recent theoretical advances in domain noise-adapted QEC, and highlighting some key open questions. We also discuss interesting connections emerged between adaptive QEC techniques fundamental physics, especially areas many-body physics cosmology. conclude brief review fault tolerance gives quantitative estimate physical threshold below error-resilient computation is possible.
