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 ...
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 ...
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, ...
Quantum Simulator for Transport Phenomena in Fluid Flows
(Nature Publishing Group, 2015-08-17)
Transport phenomena still stand as one of the most challenging problems in computational physics. By exploiting the analogies between Dirac and lattice Boltzmann equations, we develop a quantum simulator based on ...
