Nonequilibrium quantum dynamics and transport: from integrability to many-body localization [PDF]

, 2016
We review the non-equilibrium dynamics of many-body quantum systems after a quantum quench with spatial inhomogeneities, either in the Hamiltonian or in the initial state.

A classical appraisal of quantum definitions of non-Markovian dynamics

, 2012
We consider the issue of non-Markovianity of a quantum dynamics starting from a comparison with the classical definition of Markovian process. We point to the fact that two sufficient but not necessary signatures of non-Markovianity of a classical ...

Ultra‐Fast Non‐Volatile Resistive Switching Devices with Over 512 Distinct and Stable Levels for Memory and Neuromorphic Computing

Advanced Functional Materials, EarlyView.
A materials and device design concept that comprises a self‐assembled ultra‐thin epitaxial ion‐transporting layer, an amorphous oxide overcoat oxygen‐blocking layer, and a partial filament formed during an electroforming step is proposed for low‐current multilevel resistive switching devices.

Bayesian quantum noise spectroscopy

New Journal of Physics, 2018
As commonly understood, the noise spectroscopy problem—characterizing the statistical properties of a noise process affecting a quantum system by measuring its response—is mathematically ill-posed, in the sense that no unique noise process leads to a set

Quantum Spin Dynamics and Quantum Computation [PDF]

, 1999
We describe a simulation method for a quantum spin model of a generic, general purpose quantum computer. The use of this quantum computer simulator is illustrated through several implementations of Grover's database search algorithm.

Direct Characterization of Quantum Dynamics: General Theory

, 2007
The characterization of the dynamics of quantum systems is a task of both fundamental and practical importance. A general class of methods which have been developed in quantum information theory to accomplish this task is known as quantum process ...

Wetting of Surface Grafted Hydrophilic‐b‐Hydrophobic Block Copolymer Brushes

Advanced Functional Materials, EarlyView.
The wetting properties of surface grafted diblock copolymer brushes are influenced by the thickness of the hydrophilic bottom block and the hydrophobic top block. The surface adapts in presence of water and the contact angles of the bottom block shine through. Abstract The wetting of diblock copolymer brushes by water is studied.

Experimental graybox quantum system identification and control

npj Quantum Information
Understanding and controlling engineered quantum systems is key to developing practical quantum technology. However, given the current technological limitations, such as fabrication imperfections and environmental noise, this is not always possible.

Evolution equation for geometric quantum correlation measures

, 2015
A simple relation is established for the evolution equation of quantum information processing protocols such as quantum teleportation, remote state preparation, Bell-inequality violation and particularly dynamics of the geometric quantum correlation ...
