The spin degree of freedom of an electron or a nucleus is one of the most basic properties of
nature and functions as an excellent qubit, as it provides a natural two-level system that is …

Recent years have witnessed an explosion of interest in quantum devices for the production,
storage, and transfer of energy. This Colloquium concentrates on the field of quantum …

After a brief introduction to the principles and promise of quantum information processing,
the requirements for the physical implementation of quantum computation are discussed …

Quantum decoherence plays a pivotal role in the dynamical description of the quantum-to-
classical transition and is the main impediment to the realization of devices for quantum …

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 …

In the past year many developments have taken place in the area of quantum error
corrections. Recently Shor showed how to perform fault tolerant quantum computation …

Inherent symmetry of a quantum system may protect its otherwise fragile states. Leveraging
such protection requires testing its robustness against uncontrolled environmental …

Various physical implementations of quantum computers are being investigated, although
the requirements that must be met to make such devices a reality in the laboratory at present …

The recent proliferation of NISQ devices has made it imperative to understand their power. In
this work, we define and study the complexity class NISQ, which encapsulates problems that …

Quantum computation features known examples of hardware acceleration for certain
problems, but is challenging to realize because of its susceptibility to small errors from noise …
