We develop a Floquet protocol for long-range entanglement generation in the one-dimensional quantum Potts model, which generalizes the transverse-filed Ising model by allowing each spin to have n > 2 states. We focus on the case of n = 3, so that the model describes a chain of qutrits. The suggested protocol creates qutrit Bell-like pairs with non-local long-range entanglement that spans over the entire chain. We then conjecture that the proposed Floquet protocol is integrable and explicitly…

Operator Entanglement in Local Quantum Circuits II: Solitons in Chains of Qubits
We provide exact results for the dynamics of local-operator entanglement in quantum circuits with two-dimensional wires featuring ultralocal solitons, i.e. single-site operators which, up to a phase,
Multipartite entanglement in a one-dimensional time-dependent Ising model
We study multipartite entanglement measures for a one-dimensional Ising chain that is capable of showing both integrable and nonintegrable behavior. This model includes the kicked transverse Ising

The spreading of entanglement in out-of-equilibrium quantum systems is currently at the center of intense interdisciplinary research efforts involving communities with interests ranging from
Controlled generation of genuine multipartite entanglement in Floquet Ising spin models
We propose a method for generation of genuine multipartite entangled states in a short-range Ising spin chain with periodic global pulses of magnetic field. We consider an integrable and a
Entangling power of time-evolution operators in integrable and nonintegrable many-body systems
The entangling power and operator entanglement entropy are state-independent measures of entanglement. Their growth and saturation is examined in the time-evolution operator of quantum many-body
Emergent Spatial Structure and Entanglement Localization in Floquet Conformal Field Theory
We study the energy and entanglement dynamics of $(1+1)$D conformal field theories (CFTs) under a Floquet drive with the sine-square deformed (SSD) Hamiltonian. Previous work has shown this model
Operator Entanglement in Local Quantum Circuits I: Chaotic Dual-Unitary Circuits
The entanglement in operator space is a well established measure for the complexity of quantum many-body dynamics. In particular, that of local operators has recently been proposed as dynamical chaos
Exact Correlation Functions for Dual-Unitary Lattice Models in 1+1 Dimensions.
It is shown that for this class of circuits, generically nonintegrable, one can compute explicitly all dynamical correlations of local observables and this result is exact, nonpertubative, and holds for any dimension d of the local Hilbert space.
Quantum Many-Body Dynamics of Coupled Double-Well Superlattices
We propose a method for controllable generation of nonlocal entangled pairs using spinor atoms loaded in an optical superlattice. Our scheme iteratively increases the distance between entangled atoms
Quantum Kibble–Zurek mechanism and critical dynamics on a programmable Rydberg simulator
A Rydberg atom quantum simulator with programmable interactions is used to experimentally verify the quantum Kibble–Zurek mechanism through the growth of spatial correlations during quantum phase transitions, and is subsequently used to measure the critical exponents associated with chiral clock models.
