	abstract = {  Topology plays a central role in ensuring the robustness of a wide variety of
physical phenomena. Notable examples range from the robust current carrying
edge states associated with the quantum Hall and the quantum spin Hall effects
to proposals involving topologically protected quantum memory and quantum logic
operations. Here, we propose and analyze a topologically protected channel for
the transfer of quantum states between remote quantum nodes. In our approach,
state transfer is mediated by the edge mode of a chiral spin liquid. We
demonstrate that the proposed method is intrinsically robust to realistic
imperfections associated with disorder and decoherence. Possible experimental
implementations and applications to the detection and characterization of spin
liquid phases are discussed.

	abstract = {  The realization of a scalable quantum information processor has emerged over
the past decade as one of the central challenges at the interface of
fundamental science and engineering. Much progress has been made towards this
goal. Indeed, quantum operations have been demonstrated on several trapped ion
qubits, and other solid-state systems are approaching similar levels of
control. Extending these techniques to achieve fault-tolerant operations in
larger systems with more qubits remains an extremely challenging goal, in part,
due to the substantial technical complexity of current implementations. Here,
we propose and analyze an architecture for a scalable, solid-state quantum
information processor capable of operating at or near room temperature. The
architecture is applicable to realistic conditions, which include disorder and
relevant decoherence mechanisms, and includes a hierarchy of control at
successive length scales. Our approach is based upon recent experimental
advances involving Nitrogen-Vacancy color centers in diamond and will provide
fundamental insights into the physics of non-equilibrium many-body quantum
systems. Additionally, the proposed architecture may greatly alleviate the
stringent constraints, currently limiting the realization of scalable quantum
processors.
