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 …

Abstract This Technical Review collects values of selected performance characteristics of
semiconductor spin qubits defined in electrically controlled nanostructures. The …

Future quantum computers capable of solving relevant problems will require a large number
of qubits that can be operated reliably. However, the requirements of having a large qubit …

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 …

Spintronics refers commonly to phenomena in which the spin of electrons in a solid state
environment plays the determining role. In a more narrow sense spintronics is an emerging …

The coherent manipulation of individual quantum objects organized in arrays is a
prerequisite to any scalable quantum information platform. The cumulated efforts to control …

Electrons in a metal are indistinguishable particles that interact strongly with other electrons
and their environment. Isolating and detecting a single flying electron after propagation, in a …

Recent experiments have demonstrated quantum manipulation of two-electron spin states in
double quantum dots using electrically controlled exchange interactions. Here we present a …

We demonstrate electrical control of the spin relaxation time T 1 between Zeeman-split spin
states of a single electron in a lateral quantum dot. We find that relaxation is mediated by the …

The last two decades have witnessed a tremendous growth in the development and
understanding of sp 2 carbon-based nanostructures. The impact of this research has led to a …
