The interaction of solid-state qubits with environmental degrees of freedom strongly affects
the qubit dynamics, and leads to decoherence. In quantum information processing with solid …

In recent years, the physics community has experienced a revival of interest in spin effects in
solid state systems. On one hand, the solid state systems, particularly, semiconductors and …

We review recent theoretical and experimental advances toward understanding the effects
of nuclear spins in confined nanostructures. These systems, which include quantum dots …

Central spin systems, in which a central spin is singled out and interacts nonlocally with
several bath spins, are paradigmatic models for nitrogen-vacancy centers and quantum …

We polarize nuclear spins in a GaAs double quantum dot by controlling two-electron spin
states near the anticrossing of the singlet (S) and m S=+ 1 triplet (T+) using pulsed gates. An …

We study the dynamics of a single spin 1∕ 2 coupled to a bath of spins 1∕ 2 by
inhomogeneous Heisenberg couplings including a central magnetic field. This central-spin …

Very recently, the electric dipole spin resonance (EDSR) of single electrons in quantum dots
was discovered by three independent experimental groups. Remarkably, these observations …

We review recent studies on spin decoherence of electrons and holes in quasi-two-
dimensional quantum dots, as well as electron-spin relaxation in nanowire quantum dots …

We obtain analytically close forms of benchmark quantum dynamics of the collapse and
revival (CR), the reduced density matrix, Von Neumann entropy, and fidelity for the XXZ …

The dynamics and decoherence of an electronic spin-1/2 qubit coupled to a bath of nuclear
spins via hyperfine interactions in a quantum dot is studied. We show how exact results from …
