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 …

The transformation of digital computers from bulky machines to portable systems has been
enabled by new materials and advanced processing technologies that allow ultrahigh …

In the past decade, semiconducting qubits have made great strides in overcoming
decoherence, improving the prospects for scalability and have become one of the leading …

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

Spintronics, or spin electronics, involves the study of active control and manipulation of spin
degrees of freedom in solid-state systems. This article reviews the current status of this …

The canonical example of a quantum-mechanical two-level system is spin. The simplest
picture of spin is a magnetic moment pointing up or down. The full quantum properties of …

We demonstrated coherent control of a quantum two-level system based on two-electron
spin states in a double quantum dot, allowing state preparation, coherent manipulation, and …

Light–matter interactions at the single-particle level have generally been explored in the
context of atomic, molecular and optical physics. Recent advances motivated by quantum …

Experimental and theoretical progress toward quantum computation with spins in quantum
dots (QDs) is reviewed, with particular focus on QDs formed in GaAs heterostructures, on …

Spin is a fundamental property of all elementary particles. Classically it can be viewed as a
tiny magnetic moment, but a measurement of an electron spin along the direction of an …
