Effective quantum spin systems with trapped ions.
TLDR
This work shows that the physical system consisting of trapped ions interacting with lasers may undergo a rich variety of quantum phase transitions, and allows for an analogue quantum simulator of spin systems with trapped ions.
Simulating a quantum magnet with trapped ions
To gain deeper insight into the dynamics of complex quantum systems we need a quantum leap in computer simulations. We cannot translate quantum behaviour arising from superposition states or
Density matrix renormalization group and periodic boundary conditions: a quantum information perspective.
We introduce a picture to analyze the density matrix renormalization group (DMRG) numerical method from a quantum information perspective. This leads to a variational formulation of DMRG which allows
Bose-Einstein condensation and strong-correlation behavior of phonons in ion traps.
We show that the dynamics of phonons in a set of trapped ions interacting with lasers is described by a Bose-Hubbard model whose parameters can be externally adjusted. We investigate the possibility
Polariton dynamics and Bose-Einstein condensation in semiconductor microcavities
We present a theoretical model that allows us to describe the polariton dynamics in a semiconductor microcavity at large densities, for the case of nonresonant excitation. Exciton-polariton
Effective spin quantum phases in systems of trapped ions (11 pages)
A system of trapped ions under the action of off-resonant standing waves can be used to simulate a variety of quantum spin models. In this work, we describe theoretically quantum phases that can be
Experimental quantum simulations of many-body physics with trapped ions.
TLDR
An overview of different trapping techniques of ions as well as implementations for coherent manipulation of their quantum states and current approaches for scaling up to more ions and more-dimensional systems are given.
Dynamics of the excitations of a quantum dot in a microcavity
We study the dynamics of a quantum dot embedded in a three-dimensional microcavity in the strong coupling regime in which the quantum dot exciton has an energy close to the frequency of a confined
DMRG and periodic boundary conditions: a quantum information perspective
We introduce a picture to analyze the density matrix renormalization group (DMRG) numerical method from a quantum information perspective. This leads us to introduce some modifications for problems
Mesoscopic entanglement induced by spontaneous emission in solid-state quantum optics.
TLDR
This work shows that solely by controlling the position of the qubits and with the help of a coherent driving, collective spontaneous decay may be engineered to yield an entangled mesoscopic steady state.
