Fault-tolerant almost exact state transmission
(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
(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
(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
(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, ...
