In the second part of my talk, I’ll present two applications of the XZZX cluster state for increasing thresholds in both linear optical qubits and Rydberg atoms. Standard fault tolerant protocol assumes the implementation of. Thus if one can show that some error correction protocol. Correcting errors is a vital but expensive component of fault tolerant quantum computation. In the first part of the talk, I’ll explain the basics of measurement-based error correction and cluster states, and show how a cluster state derived from the XZZX surface code, the so-called XZZX cluster state, can effectively correct biased noise. Quantum error correction was developed in analogy with classical error correcting codes. In this talk, I’ll present recent work on tailoring measurement-based quantum computing to biased noise. 1 National Institute of Informatics, 2-1-2 Hitotsubashi Chiyoda-ku Tokyo, 101-8340, Japan. F rom a merely theoretical point of view, there is no doubt that quantum computers would have extraordinary power, but concretely we have to face the truth and fight against the existence of noise and errors. One promising approach to reducing the overheads of error correction is to tailor quantum error correcting codes to the dominant noise in the qubit hardware. However, the hardware overhead for error correction remains dauntingly large, with each logical qubit potentially requiring thousands of physical qubits for reliable operation. Presented by: Jahan Claes, Yale UniversityĪbstract: Large-scale quantum computers will require error correction in order to reliably perform computations.
