Quantum simulations

Edited by: Prof Dieter Jaksch, Prof Dimitris Angelakis, Alan Aspuru-Guzik, Prof Enrique Solano

Quantum simulations consist in the intentional reproduction of interesting physical phenomena, usually notoriously difficult to study in the lab and on a computer, onto another quantum system that is typically more accessible and controllable. Most if not all of the real effects occurring in condensed matter and quantum chemistry, or predicted by nuclear physics and the Standard Model, are in this category due to our limited computational capabilities in modeling quantum many body systems. A working quantum simulator is expected to be able to assist in overcoming the above issues by directly reproducing the inner workings of the system itself in a controlled environment.

  1. Numerical methods for the 1-D Dirac equation based on operator splitting and on the quantum lattice Boltzmann (QLB) schemes are reviewed. It is shown that these discretizations fall within the class of quantum...

  2. We develop the theory to describe the equilibrium ion positions and phonon modes for a trapped ion quantum simulator in an oblate Paul trap that creates two-dimensional Coulomb crystals in a triangular lattice...

  3. We study the out-of-equilibrium dynamics of bosonic atoms in a 1D optical lattice, after the ground-state is excited by a single spontaneous emission event, i.e. after an absorption and re-emission of a lattic...

  4. We study a quantum quench in the Bose-Hubbard model where the tunneling rate J is suddenly switched from zero to a finite value in the Mott regime. In order to solve the many-body quantum dynamics far from equili...

  5. Quantum simulators are devices that actively use quantum effects to answer questions about model systems and, through them, real systems. In this review we expand on this definition by answering several fundam...
