TL;DR: Here, a quantum simulator composed of up to 53 qubits is used to study non-equilibrium dynamics in the transverse-field Ising model with long-range interactions, enabling the dynamical phase transition to be probed directly and revealing computationally intractable features that rely on the long- range interactions and high connectivity between qubits.

TL;DR: This work demonstrates a medium that is nonlinear at the level of individual quanta, exhibiting strong absorption of photon pairs while remaining transparent to single photons, paving the way for quantum-by-quantum control of light fields, including single-photon switching, all-optical deterministic quantum logic and the realization of strongly correlated many-body states of light.

TL;DR: This work applies a variable-range Ising spin chain Hamiltonian and aVariable-range XY spin chainHamiltonian to a far-from-equilibrium quantum many-body system and observes its time evolution, determining the spatial and time-dependent correlations, extracting the shape of the light cone and measuring the velocity with which correlations propagate through the system.

TL;DR: In this paper, the decoupling of the nuclear spin from the electronic angular momentum is used to implement many-body systems with an unprecedented degree of symmetry, characterized by the SU(N)group withNaslargeas10.

TL;DR: In this paper, an atom trapped near a photonic crystal seeds a localized, tunable cavity mode around the atomic position, which facilitates interactions with other atoms within the cavity length, in a way that can be made robust against realistic imperfections.
