Experimental demonstration of topological error correction

摘要: Scalable quantum computing can be achieved only if bits are manipulated in a fault-tolerant fashion. Topological error correction—a method that combines topological computation with correction—has the highest known tolerable rate for local architecture. The technique makes use of cluster states properties and requires nearest-neighbour interactions. Here we report experimental demonstration correction an eight-photon state. We show correlation protected against single on any bit. Also, when all simultaneously subjected to errors equal probability, effective significantly reduced. Our work demonstrates viability information processing. Fault-tolerant manipulation is demonstrated experimentally state using correction. Quantum more prone than processes involved classical computers, so scalable or qubits carry information. One most promising methods minimizing caused by qubit decoherence correction, which This paper reports first proof-of-principle important demonstration, requiring state-of-the-art optics technology.
