TY - JOUR T1 - Topologically Protected Quantum State Transfer in a Chiral Spin Liquid JF - Nature Communications Y1 - 2013 A1 - Norman Y. Yao A1 - Chris R. Laumann A1 - Alexey V.

Lukin AB - 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.
