This introductory review discusses the main problems facing the attempt to build quantum
information processing systems (like quantum computers) from spin-based qubits. We …

Magnetic solids should, under certain circumstances, show macroscopic quantum behavior,
in which coherence exists between completely distinct magnetization states, each involving …

We argue that to explain recent resonant tunneling experiments on crystals of Mn 12 and Fe
8, particularly in the low-T limit, one must invoke dynamic nuclear spin and dipolar …

Quantum decoherence is a central concept in physics. Applications such as quantum information
processing depend on understanding it; there are even fundamental theories proposed …

We construct a mapping between the two-dimensional toric code model in external
magnetic fields, hz and hx, and the three-dimensional classical Ising system with plaquette …

Recent advances in cooling, control, and measurement of mechanical systems in the quantum
regime have opened the possibility of the first direct observation of quantum gravity, at …

We study a single polaron in the Su-Schrieffer-Heeger (SSH) model using four different
techniques (three numerical and one analytical). Polarons show a smooth crossover from weak …

Experiments involving phase coherent dynamics of networks of spins, such as echo
experiments, will only work if decoherence can be suppressed. We show here, by analyzing the …

At temperatures below the magnetic anisotropy energy, monodomain magnetic systems (small
particles, nanomagnetic devices, etc.) must relax quantum mechanically-thermal …
