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 …

To process information using quantum-mechanical principles, the states of individual
particles need to be entangled and manipulated. One way to do this is to use trapped, laser …

Entanglement purification protocols (EPPs) and quantum error-correcting codes (QECCs)
provide two ways of protecting quantum states from interaction with the environment. In an …

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 …

We propose a scheme to utilize photons for ideal quantum transmission between atoms
located at spatially separated nodes of a quantum network. The transmission protocol …

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 …

The problem of finding quantum error correcting codes is transformed into the problem of
finding additive codes over the field GF (4) which are self-orthogonal with respect to a …

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 …

It is vital to minimize the impact of errors for near-future quantum devices that will lack the
resources for full fault tolerance. Two quantum error mitigation (QEM) techniques have been …

Methods for, and limitations to, the generation of entangled states of trapped atomic ions are
examined. As much as possible, state manipulations are described in terms of quantum …
