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

Trapping single atoms on a nanophotonic circuit with configurable tweezer lattices.
TL;DR: In this paper, a configurable optical tweezer array over a planar photonic circuit is implemented for cold atom integration and control for trapping and high-fidelity imaging of one or more atoms in an array directly on a photonic structure.

Quantum State Tomography with Conditional Generative Adversarial Networks
TL;DR: This work applies conditional generative adversarial networks (CGANs) to QST and demonstrates that the QST-CGAN reconstructs optical quantum states with high fidelity, using orders of magnitude fewer iterative steps, and less data, than both accelerated projected-gradient-based and iterative maximum-likelihood estimation.

Entangling polaritons via dynamical Casimir effect in circuit quantum electrodynamics
D. Z. Rossatto,D. Z. Rossatto,Simone Felicetti,H. Eneriz,Enrique Rico,Enrique Rico,Mikel Sanz,Enrique Solano,Enrique Solano +8 more
TL;DR: In this paper, the authors investigated how the dynamical Casimir effect can entangle quantum systems in different coupling regimes of circuit quantum electrodynamics, and show the robustness of such entanglement generation against dissipative effects.

TL;DR: In this article, a yttrium-iron-garnet sphere coupled strongly to a microwave cavity over the full temperature range from 0.28em to 30m was investigated, where the thermal energy is less than one resonant microwave quanta.

Algorithms for quantum simulation at finite energies
TL;DR: A quantum algorithm to compute expectation values of observables in a finite energy interval for many-body problems based on a filtering operator, similar to quantum phase estimation, which recovers the physical values by performing interferometric measurements without the need to prepare the filtered state.

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.
