High fidelity quantum gates of trapped ions in the presence of motional heating
New Journal of Physics, 2016 We describe entangling quantum gates for trapped ions mediated by a dissipative bus mode and show that suitably designed, polychromatic control pulses decrease ion-phonon entanglement substantially while maintaining the mediated interaction.

Elementary solution to the time-independent quantum navigation problem [PDF]
, 2015 A quantum navigation problem concerns the identification of a time-optimal Hamiltonian that realizes a required quantum process or task, under the influence of a prevailing ‘background’ Hamiltonian that cannot be manipulated.

Quantum dynamics of the damped harmonic oscillator [PDF]
, 2012 Copyright © 2012 Institute of PhysicsOpen Access journalThe quantum theory of the damped harmonic oscillator has been a subject of continual investigation since the 1930s. The obstacle to quantization created by the dissipation of energy is usually dealt

Quantum correlations and limit cycles in the driven-dissipative Heisenberg lattice
New Journal of Physics, 2018 Driven-dissipative quantum many-body systems have attracted increasing interest in recent years as they lead to novel classes of quantum many-body phenomena.

Void formation in operator growth, entanglement, and unitarity
Journal of High Energy Physics, 2021 The structure of the Heisenberg evolution of operators plays a key role in explaining diverse processes in quantum many-body systems. In this paper, we discuss a new universal feature of operator evolution: an operator can develop a void during its ...

, 2005 In a totally dissipative behavior, all non-trivial trajectories dissipate energy. A characterization of such behaviors is given in terms of properties of the one- and two-polynomial matrices associated with the supply rate and with their kernel- and ...

Dissipative quantum many-body dynamics in (1+1)D quantum cellular automata and quantum neural networks [PDF]
, 2023 Classical artificial neural networks, built from elementary units, possess enormous expressive power. Here we investigate a quantum neural network architecture, which follows a similar paradigm.

Parametrically driving a quantum oscillator into exceptionality
Scientific Reports, 2023 The mathematical objects employed in physical theories do not always behave well. Einstein’s theory of space and time allows for spacetime singularities and Van Hove singularities arise in condensed matter physics, while intensity, phase and polarization

A simple tensor network algorithm for two-dimensional steady states
Nature Communications, 2017 Our understanding of open quantum many-body systems is limited because it is difficult to perform a theoretical treatment of both quantum and dissipative effects in large systems.

A random unitary circuit model for black hole evaporation
Journal of High Energy Physics, 2020 Inspired by the Hayden-Preskill protocol for black hole evaporation, we consider the dynamics of a quantum many-body qudit system coupled to an external environment, where the time evolution is driven by the continuous limit of certain 2-local random ...
