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.

    Quantum lattice Boltzmann is a quantum walk

    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...

    Phase diagram of a QED-cavity array coupled via a N-type level scheme

    We study the zero-temperature phase diagram of a one-dimensional array of QED cavities where, besides the single-photon hopping, an additional coupling between neighboring cavities is mediated by an N-type four-l...

    What is a quantum simulator?

    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...

    Efficient quantum simulation of fermionic and bosonic models in trapped ions

    We analyze the efficiency of quantum simulations of fermionic and bosonic models in trapped ions. In particular, we study the optimal time of entangling gates and the required number of total elementary gates....

    Trapped-ion quantum simulation of tunable-range Heisenberg chains

    Quantum-optical techniques allow for generating controllable spin-spin interactions between ions, making trapped ions an ideal quantum simulator of Heisenberg chains. A single parameter, the detuning of the Ra...
