The development of small-scale quantum devices raises the question of how to fairly assess
and detect quantum speedup. Here, we show how to define and measure quantum speedup …

Quantum computers, though not yet available on the market, will revolutionize the future of
information processing. Quantum computers for special purposes like quantum simulators …

We review recent developments in the physics of ultracold atomic and molecular gases in
optical lattices. Such systems are nearly perfect realisations of various kinds of Hubbard …

Recently, a programmable quantum annealing machine has been built that minimizes the
cost function of hard optimization problems by, in principle, adiabatically quenching …

Monte Carlo simulations are methods for simulating statistical systems. The aim is to
generate a representative ensemble of configurations to access thermodynamical quantities …

There has been considerable progress in the design and construction of quantum annealing
devices. However, a conclusive detection of quantum speedup over traditional silicon-based …

Low-temperature properties of crystalline solids can be understood using harmonic
perturbations around a perfect lattice, as in Debye's theory. Low-temperature properties of …

We argue that for generic systems close to a critical point, an extended fluctuation-
dissipation relation connects the low frequency nonlinear (cubic) susceptibility to the four …

Presenting an up-to-date report on electronic glasses, this book examines experiments and
theories for a variety of disordered materials where electrons exhibit glassy properties …

Overcoming the conventional trade-off between throughput and bit error rate (BER)
performance, versus computational complexity is a long-term challenge for uplink Multiple …
