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 …

Computers are physical systems: the laws of physics dictate what they can and cannot do. In
particular, the speed with which a physical device can process information is limited by its …

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 …

The emergence of quantum computers as a new computational paradigm has been
accompanied by speculation concerning the scope and timeline of their anticipated …

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 …

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 …

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 …

Quantum error correction requires the detection of errors via reliable measurements of
multiqubit correlation operators. As these operations are inherently faulty, fault-tolerant …

In the hard sciences, which can often feel out of grasp for many lay readers, there are" great
thinkers" who go far beyond the equations, formulas, and research. Minds such as Stephen …
