Quantum versus classical annealing: insights from scaling theory and results for spin glasses on 3-regular graphs
Cheng-Wei Liu, Anatoli Polkovnikov, Anders W. Sandvik
We discuss an Ising spin glass where each spin is coupled antiferromagnetically to three other spins (3-regular graphs). Inducing quantum fluctuations by a time-dependent t…
Stationary ensemble approximations of dynamic quantum states: Optimizing the Generalized Gibbs Ensemble
Dries Sels, Michiel Wouters
We reconsider the non-equilibrium dynamics of closed quantum systems. In particular we focus on the thermalization of integrable systems. Here we show how the generalized Gibbs Ens…
Supersymmetry in quantum optics and in spin-orbit coupled systems
Michael Tomka, Mikhail Pletyukhov, Vladimir Gritsev
Light-matter interaction is naturally described by coupled bosonic and fermionic subsystems. This suggests that a certain Bose-Fermi duality is naturally present in the fundamental…
Observation of topological transitions in interacting quantum circuits
P. Roushan, C. Neill, Yu Chen +21
The discovery of topological phases in condensed matter systems has changed the modern conception of phases of matter. The global nature of topological ordering makes these phases…
Irreversibility and Entanglement Spectrum Statistics in Quantum Circuits
Daniel Shaffer, Claudio Chamon, Alioscia Hamma +1
We show that in a quantum system evolving unitarily under a stochastic quantum circuit the notions of irreversibility, universality of computation, and entanglement are closely rel…
Measuring a topological transition in an artificial spin 1/2 system
M. D. Schroer, M. H. Kolodrubetz, W. F. Kindel +6
We present measurements of a topological property, the Chern number (), of a closed manifold in the space of two-level system Hamiltonians, where the two-level system…
SU(3) semiclassical representation of quantum dynamics of interacting spins
Shainen M. Davidson, Anatoli Polkovnikov
We present a formalism for simulating quantum dynamics of lattice spin-one systems by first introducing local hidden variables and then doing semiclassical (truncated Wigner) appro…
Quantum Evolution Time Limit: a General Non-Markovian Bound
Xiangyi Meng, Chengjun Wu, Hong Guo
We derive a sharp bound as the quantum speed limit (QSL) for the minimal evolution time of quantum open systems in the non-Markovian strong-coupling regime with initial mixed state…
