TLDR
The main theoretical and experimental aspects of quantum simulation have been discussed in this article, and some of the challenges and promises of this fast-growing field have also been highlighted in this review.Abstract:
Simulating quantum mechanics is known to be a difficult computational problem, especially when dealing with large systems However, this difficulty may be overcome by using some controllable quantum system to study another less controllable or accessible quantum system, ie, quantum simulation Quantum simulation promises to have applications in the study of many problems in, eg, condensed-matter physics, high-energy physics, atomic physics, quantum chemistry and cosmology Quantum simulation could be implemented using quantum computers, but also with simpler, analog devices that would require less control, and therefore, would be easier to construct A number of quantum systems such as neutral atoms, ions, polar molecules, electrons in semiconductors, superconducting circuits, nuclear spins and photons have been proposed as quantum simulators This review outlines the main theoretical and experimental aspects of quantum simulation and emphasizes some of the challenges and promises of this fast-growing fieldread more

Nonlinear graphene quantum capacitors for electro-optics
TL;DR: In this paper, a three-layer device made of two graphene layers separated by a two-dimensional dielectric was proposed for superconducting quantum circuits, and it is shown that ultrastrong coupling is easily reached with small number of pump photons at temperatures around 1'K and capacitor areas of the order of 1'μm2.

Optical analogues of black-hole horizons.
TL;DR: This article discusses the central and recent experiments of the optical analogue of the black-hole horizon and Hawking radiation that is made of light, and stresses the roles of classical fields, negative frequencies, ‘regular optics' and dispersion.

Simulating Hydrodynamics on Noisy Intermediate-Scale Quantum Devices with Random Circuits.
Jonas Richter,Arijeet Pal +1 more
TL;DR: In this paper, a random circuit is used to simulate quantum many-body systems on noisy intermediate-scale quantum (NISQ) devices, and a trotterized Hamiltonian time evolution is employed to extract transport coefficients in the linear response regime.

Many-Body Physics with Ultracold Gases
TL;DR: In this article, a review of recent experimental and theoretical progress concerning many-body phenomena in dilute, ultracold gases is presented, focusing on effects beyond standard weakcoupling descriptions, such as the Mott-Hubbard transition in optical lattices, strongly interacting gases in one and two dimensions, or lowest-Landau-level physics in quasi-two-dimensional gases in fast rotation.
Journal ArticleDOI
The quantum internet
TL;DR: In this paper, the authors proposed a method for quantum interconnects, which convert quantum states from one physical system to those of another in a reversible manner, allowing the distribution of entanglement across the network and teleportation of quantum states between nodes.

Quantum Phase Transition From a Superfluid to a Mott Insulator in a Gas of Ultracold Atoms
TL;DR: This work observes a quantum phase transition in a Bose–Einstein condensate with repulsive interactions, held in a three-dimensional optical lattice potential, and can induce reversible changes between the two ground states of the system.
