The book is not limited to a single approach, but reviews many different methods to control quantum errors, including topological codes, dynamical decoupling and decoherence-free subspaces. Many promising quantum technologies, ranging from powerful quantum computers to ultra-sensitive measuring devices, are currently being developed and tested in small-scale experiments around the globe.
SURVEY OF QUANTUM ERROR CORRECTION CODES CODE
A special class of quantum erasureerror correction (QEEC) code was. This comprehensive text, written by leading experts in the field, focuses on quantum error correction and thoroughly covers the theory as well as experimental and practical issues. We now briefly review the quantum codes designed to tackle the problem of qubit loss. Scalable quantum computers require a far-reaching theory of fault-tolerant quantum computation. The error-correction demonstration was performed on Schrodinger-cat states encoded in a superconducting resonator, and employed a quantum controller capable of performing real-time feedback operations including read-out of the quantum information, its analysis, and the correction of its detected errors. This decoherence is countered by quantum error-correcting codes (QECCs), analogous to.
To achieve large scale quantum computers and communication networks it is essential not only to overcome noise in stored quantum information, but also in general faulty quantum operations. channels are noisy, causing decoherence of the transmitted states. Quantum computation and information is one of the most exciting developments in science and technology of the last twenty years. In this article, we review the recent progress of the bosonic codes, including the Gottesman-Kitaev-Preskill codes, cat codes, and binomial codes, and discuss.
