We present quantitative predictions for quantum simulator experiments on Ising models from trapped ions to Rydberg chains and show how the thermalization, and thus decoherence times, can be controlled by considering common, independent, and end-cap couplings to the bath. We find (i) independent baths enable more rapid thermalization in comparison to a common one; (ii) the thermalization timescale depends strongly on the position in the Ising phase diagram; (iii) for a common bath larger system… 
Entanglement and complexity of interacting qubits subject to asymmetric noise
It is argued that quantum sampling problems including nontrivial noise could be good candidates for demonstrating a quantum advantage in near-term hardware, and metrics which suggest classical intractability for the isolated chain point to similar conclusions in the noisy case.
Theoretical survey of unconventional quantum annealing methods applied to adifficult trial problem.
We consider a range of unconventional modifications to Quantum Annealing (QA), applied to an artificial trial problem with continuously tunable difficulty. In this problem, inspired by "transverse
Classical critical dynamics in quadratically driven Kerr resonators
Driven-dissipative kerr lattices with two-photon driving are experimentally relevant systems known to exhibit a symmetry-breaking phase transition, which belongs to the universality class of the
Bosonic representation of a Lipkin-Meshkov-Glick model with Markovian dissipation
We study the dynamics of a Lipkin-Meshkov-Glick model in the presence of Markovian dissipation, with a focus on late-time dynamics and the approach to thermal equilibrium. Making use of a vectorized
Open source matrix product states: exact diagonalization and other entanglement-accurate methods revisited in quantum systems
Tensor network methods as presented in our open source matrix product states software have opened up the possibility to study many-body quantum physics in one and quasi-one-dimensional systems in an
Response of quantum spin networks to attacks
The ground states of spin models defined on networks that are imprinted and their response to decohering processes which the authors model with network attacks are investigated, and it is indicated that complex spin networks are not more robust to projective measurement attacks than non-complex spin networks, in contrast to the classical case.
Stationary state degeneracy of open quantum systems with non-abelian symmetries
We study the null space degeneracy of open quantum systems with multiple non-abelian, strong symmetries. By decomposing the Hilbert space representation of these symmetries into an irreducible
Numerical simulation of critical dissipative non-equilibrium quantum systems with an absorbing state
The simulation of out-of-equilibrium dissipative quantum many body systems is a problem of fundamental interest to a number of fields in physics, ranging from condensed matter to cosmology. For
Noise-tolerant quantum speedups in quantum annealing without fine tuning
A modification of flux qubit-based quantum annealing which includes low-frequency oscillations in the directions of the transverse field terms as the system evolves, which produces a quantum speedup for finding ground states in the Grover problem and quantum random energy model, and should be widely applicable to other hard optimization problems which can be formulated as quantum spin glasses.


Critical phenomena and Kibble–Zurek scaling in the long-range quantum Ising chain
We investigate an extension of the quantum Ising (QI) model in one spatial dimension including long-range 1 / r α interactions in its statics and dynamics with possible applications from
Realizing quantum Ising models in tunable two-dimensional arrays of single Rydberg atoms
Spin models are the prime example of simplified manybody Hamiltonians used to model complex, real-world strongly correlated materials. However, despite their simplified character, their dynamics
Phase transitions in the quantum Ising and rotor models with a long-range interaction
We investigate the zero-temperature and finite-temperature phase transitions of quantum Ising and quantum rotor models. We here assume a long-range (falling off as 1/r d+σ , where r is the distance
From quantum chaos and eigenstate thermalization to statistical mechanics and thermodynamics
This review gives a pedagogical introduction to the eigenstate thermalization hypothesis (ETH), its basis, and its implications to statistical mechanics and thermodynamics. In the first part, ETH is
Dissipative quantum Ising model in a cold-atom spin-boson mixture
Using cold bosonic atoms with two (hyperfine) ground states, we introduce a spin-boson mixture which allows to implement the quantum Ising model in a tunable dissipative environment. The first specie

Algebraic versus Exponential Decoherence in Dissipative Many-Particle Systems.
Investigation of spin-1/2 chains with uniform local couplings to a Markovian environment using the time-dependent density matrix renormalization group finds that the decoherence time diverges in the thermodynamic limit, and the coherence decay is then algebraic instead of exponential.
Nonreciprocal quantum transport at junctions of structured leads
We propose and analyze a mechanism for rectification of spin transport through a small junction between two spin baths or leads. For interacting baths, we show that transport is conditioned on the

We analyze the quantum phases, correlation functions and edge modes for a class of spin-1/2 and fermionic models related to the one-dimensional Ising chain in the presence of a transverse field.
Equilibration, thermalisation, and the emergence of statistical mechanics in closed quantum systems.
This work reviews selected advances in the theoretical understanding of complex quantum many-body systems with regard to emergent notions of quantum statistical mechanics and elucidate the role played by key concepts, such as Lieb-Robinson bounds, entanglement growth, typicality arguments, quantum maximum entropy principles and the generalised Gibbs ensembles.
