	abstract = {  Strongly correlated quantum systems can exhibit exotic behavior controlled by
topology. We predict that the \nu=1/2 fractional Chern insulator arises
naturally in a two-dimensional array of driven, dipolar-interacting spins. As a
specific implementation, we analyze how to prepare and detect synthetic gauge
potentials for the rotational excitations of ultra-cold polar molecules trapped
in a deep optical lattice. While the orbital motion of the molecules is pinned,
at finite densities, the rotational excitations form a fractional Chern
insulator. We present a detailed experimental blueprint for KRb, and
demonstrate that the energetics are consistent with near-term capabilities.
Prospects for the realization of such phases in solid-state dipolar systems are
discussed as are their possible applications.

	title = {Robust Quantum State Transfer in Random Unpolarized Spin Chains},
	journal = {Physical Review Letters},

	abstract = {  We propose and analyze a new approach for quantum state transfer between
remote spin qubits. Specifically, we demonstrate that coherent quantum coupling
between remote qubits can be achieved via certain classes of random,
unpolarized (infinite temperature) spin chains. Our method is robust to
coupling strength disorder and does not require manipulation or control over
individual spins. In principle, it can be used to attain perfect state transfer
over arbitrarily long range via purely Hamiltonian evolution and may be
particularly applicable in a solid-state quantum information processor. As an
example, we demonstrate that it can be used to attain strong coherent coupling
between Nitrogen-Vacancy centers separated by micrometer distances at room
temperature. Realistic imperfections and decoherence effects are analyzed.
