      Fault-tolerant almost exact state transmission 

      Wang, Zhao-Ming; Wu, Lianao; Modugno, Michele; Yao, Wang; Shao, Bin (Nature Publishing Group, 2013-11)
      We show that a category of one-dimensional XY-type models may enable high-fidelity quantum state transmissions, regardless of details of coupling configurations. This observation leads to a fault-tolerant design of a state ...

      High- fi delity non-adiabatic cutting and stitching of a spin chain via local control 

      Pyshkin, P. V.; Sherman, Evgeny; You, J. Q.; Wu, Lianao (IOP Publishing, 2018-10-18)
      We propose and analyze, focusing on non-adiabatic effects, a technique of manipulating quantum spin systems based on local 'cutting' and 'stitching' of the Heisenberg exchange coupling between the spins. This first operation ...

      Nonperturbative dynamical decoupling with random control 

      Wu, Lianao; Bishop, C.Allen; Jing, Jun (Nature Publishing Group, 2014-08-29)
      Parametric fluctuations or stochastic signals are introduced into the rectangular pulse sequence to investigate the feasibility of random dynamical decoupling. In a large parameter region, we find that the out-of-order ...

      Symmetry restoration and quantumness reestablishment 

      Zeng, Guo-Mo; Wu, Lianao; Xing, Hai-Jun (Nature Publishing Group, 2014-09-18)
      A realistic quantum many-body system, characterized by a generic microscopic Hamiltonian, is accessible only through approximation methods. The mean field theories, as the simplest practices of approximation methods, ...
