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 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 …

The control of individual quantum systems promises a new technology for the 21st century-
quantum technology. This book is the first comprehensive treatment of modern quantum …

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 …

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

The strong coupling limit of cavity quantum electrodynamics (QED) implies the capability of a
matterlike quantum system to coherently transform an individual excitation into a single …

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 …

We study quantum coherence in a semiconductor charge qubit formed from a GaAs double
quantum dot containing a single electron. Voltage pulses are applied to depletion gates to …

We have prepared two ultracold fermionic atoms in an isolated double-well potential and
obtained full control over the quantum state of this system. In particular, we can …

The similarities between gated quantum dots and the transistors in modern microelectronics,—
in fabrication methods, physical structure and voltage scales for manipulation—have led to …
