Realization of quantum Maxwell's demon with solid-state spins

W. -B. Wang, X. -Y. Chang, F. Wang +8

Resolution of the century-long paradox on Maxwell's demon reveals a deep connection between information theory and thermodynamics. Although initially introduced as a thought experi…

Statistically preferred basis of an open quantum system: Its relation to the eigenbasis of a renormalized self-Hamiltonian

Lewei He, Wen-ge Wang

We study the problem of the basis of an open quantum system, under a quantum chaotic environment, which is preferred in view of its stationary reduced density matrix (RDM), that is…

Preferred States of Decoherence under Intermediate System-Environment Coupling

Wen-ge Wang, Lewei He, Jiangbin Gong

The notion that decoherence rapidly reduces a superposition state to an incoherent mixture implicitly adopts a special representation, namely, the representation of preferred (poin…

Efficiency of dynamical decoupling sequences in presence of pulse errors

Zhihao Xiao, Lewei He, Wen-ge Wang

For a generic dynamical decoupling sequence employing a single-axis control, we study its efficiency in the presence of small errors in direction of the controlling-pulses. In the…

Semiclassical Approach to Survival Probability at Quantum Phase Transitions

Wen-ge Wang, Pinquan Qin, Lewei He +1

We study the decay of survival probability at quantum phase transitions (QPT). The semiclassical theory is found applicable in the vicinities of critical points with infinite degen…
