Journal ArticleDOI
Controlling Complex Networks: How Much Energy Is Needed?
TL;DR: This work addresses the physically important issue of the energy required for achieving control by deriving and validating scaling laws for the lower and upper energy bounds.
Journal ArticleDOI
Nonadiabatic geometric quantum computation
Z.S. Wang,Chunfeng Wu,Xun-Li Feng,Leong Chuan Kwek,Leong Chuan Kwek,Choy Heng Lai,Choo Hiap Oh,Vlatko Vedral,Vlatko Vedral +8 more
TL;DR: In this article, a different way to realize nonadiabatic geometric quantum computation is proposed by varying parameters in the Hamiltonian for nuclear-magnetic resonance, where the dynamical and geometric phases are implemented separately without the usual operational process.
Journal ArticleDOI
Adaptive–impulsive synchronization of uncertain complex dynamical networks
Kun Li,Choy Heng Lai +1 more
TL;DR: Based on the stability analysis of impulsive system, several network synchronization criteria for local and global adaptive-impulsive synchronization are established in this paper, and a numerical example is also given to illustrate the results.

Extracting Messages Masked by Chaotic Signals of Time-delay Systems
Changsong Zhou,Choy Heng Lai +1 more
TL;DR: In this paper, the authors proposed a method to extract messages masked by a chaotic signal of a time-delay system with very high dimension and many positive Lyapunov exponents using a special embedding coordinate.

Extracting messages masked by chaotic signals of time-delay systems.
Changsong Zhou,Choy Heng Lai +1 more
TL;DR: This work shows how to extract messages masked by a chaotic signal of a time-delay system with very high dimensions and many positive Lyapunov exponents from the transmitted signal and reconstruct the chaotic dynamics to unmask the hidden message successfully.
