Active quantum error correction using qubit stabilizer codes has emerged as a promising,
but experimentally challenging, engineering program for building a universal quantum …

Quantum error correction protocols will play a central role in the realisation of quantum
computing; the choice of error correction code will influence the full quantum computing …

Suppressing errors is the central challenge for useful quantum computing, requiring
quantum error correction (QEC),,,–for large-scale processing. However, the overhead in the …

In quantum communication via noisy channels, the error probability scales exponentially
with the length of the channel. We present a scheme of a quantum repeater that overcomes …

Controlling operational errors and decoherence is one of the major challenges facing the
field of quantum computation and other attempts to create specified many-particle entangled …

The superposition principle plays the most central role in all considerations of quantum
information, and in most of the" gedanken" experiments and even the paradoxes of quantum …

We analyze surface codes, the topological quantum error-correcting codes introduced by
Kitaev. In these codes, qubits are arranged in a two-dimensional array on a surface of …

Over the course of the past decade, decoherence has become a ubiquitous scienti? c term
popular in all kinds of research, from fundamental theories of quantum physics to …

The subject of quantum computing brings together ideas from classical information theory,
computer science, and quantum physics. This review aims to summarize not just quantum …

The promise of quantum computers hinges on the ability to scale to large system sizes, eg,
to run quantum computations consisting of more than 100 million operations fault-tolerantly …
