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 mesoscopic spin system formed by the 10 4–10 6 nuclear spins in a semiconductor
quantum dot offers a unique setting for the study of many-body spin physics in the …

The ability to control the quantum state of a single electron spin in a quantum dot is at the
heart of recent developments towards a scalable spin-based quantum computer. In …

We have demonstrated laser cooling of a single electron spin trapped in a semiconductor
quantum dot. Optical coupling of electronic spin states was achieved using resonant …

Many proposed photonic quantum networks rely on matter qubits to serve as memory
elements,. The spin of a single electron confined in a semiconductor quantum dot forms a …

The fast dephasing of electron spins in an ensemble of quantum dots is detrimental for
applications in quantum information processing. We show here that dephasing can be …

Confined spins in self-assembled semiconductor quantum dots promise to serve both as
probes for studying mesoscopic physics in the solid state and as stationary qubits for …

Using spin to replace or augment the role of charge in signal processing devices, computing
systems and circuits may improve speed, power consumption, and device density in some …

In this paper, we propose a quantum interference mediated control of switching between
magnon-atom entanglement and magnon blockade. A three-level Λ configuration atomic …

We present a quantum solution to the electron spin decoherence by a nuclear pair-
correlation method for the electron-nuclear spin dynamics under a strong magnetic field and …
