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 …

Over the past several decades, quantum information science has emerged to seek answers
to the question: can we gain some advantage by storing, transmitting and processing …

Stable quantum bits, capable both of storing quantum information for macroscopic time
scales and of integration inside small portable devices, are an essential building block for an …

Understanding and controlling the complex environment of solid-state quantum bits is a
central challenge in spintronics and quantum information science. Coherent manipulation of …

Quantum memories capable of storing and retrieving coherent information for extended
times at room temperature would enable a host of new technologies. Electron and nuclear …

A quantum computer requires systems that are isolated from their environment, but can be
integrated into devices, and whose states can be measured with high accuracy. Nuclear …

Some of the stable isotopes of silicon and carbon have zero nuclear spin, whereas many of
the other elements that constitute semiconductors consist entirely of stable isotopes that …

Quantum computers hold the promise of massive performance enhancements across a
range of applications, from cryptography and databases to revolutionary scientific simulation …

In many realizations of electron spin qubits the dominant source of decoherence is the
fluctuating nuclear spin bath of the host material. The slowness of this bath lends itself to a …

We describe a quantum repeater protocol for long-distance quantum communication. In this
scheme, entanglement is created between qubits at intermediate stations of the channel by …
