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.Expand

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.Expand

It is demonstrated that coherent quantum coupling between remote qubits can be achieved via certain classes of random, unpolarized (infinite temperature) spin chains through a new approach to quantum state transfer between remote spin qubits.Expand

The proposed space-time crystals of trapped ions provide a new dimension for exploring many-body physics and emerging properties of matter and are robust for direct experimental observation.Expand

This work rules out the possibility that light cones of power-law interacting systems are bounded by a polynomial for α>2D and become linear as α→∞, suggesting that the velocity, as calculated from the slope of the light cone, may grow exponentially in time.Expand

A long-range interacting spin chain with U(1) symmetry and power-law interactions V(r)∼1/r^{α) is studied, finding CSB for α smaller than a critical exponent α_{c}(≤3) that depends on the microscopic parameters of the model.Expand

A finite-temperature phase diagram is determined for trapped ions using the renormalization group method and the path integral formalism and an experimental scheme is proposed to observe the predicted temperature-driven structural phase transition, which is well within the reach of the current ion trap technology.Expand

The nonequilibrium dynamics of Abelian anyons in a one-dimensional system is studied and it is shown that anyonic statistics induces asymmetric spreading of quantum information, characterized by asymmetric light cones of out-of-time-ordered correlators.Expand

The maximum speed with which information can propagate in a quantum many-body system directly affects how quickly disparate parts of the system can become correlated [1–4] and how difficult the… Expand

This work demonstrates entangling quantum gates within a chain of five trapped ion qubits by optimally shaping optical fields that couple to multiple collective modes of motion and enables high-fidelity gates that can be scaled to larger qubit registers for quantum computation and simulation.Expand
