The idiots guide to Quantum Error Correction

摘要: Quantum error correction (QEC) and fault-tolerant quantum computation represent one of the most vital theoretical aspect information processing. It was well known from early developments this exciting field that fragility coherent systems would be a catastrophic obstacle to development large scale computers. The introduction in 1995 showed active techniques could employed mitigate fatal problem. However, is now much larger many new codes, techniques, methodologies have been developed implement for algorithms. In response, we attempted summarize basic aspects fault-tolerance, not as detailed guide, but rather introduction. This area has so pronounced information, specifically researchers who are or people focused on other important issues computation, found it difficult keep up with general formalisms area. Rather than introducing these concepts rigorous mathematical computer science framework, instead examine fault-tolerance largely through examples, which more relevant experimentalists today near future.
