A sufficient and necessary condition for superdense coding of quantum states
Daowen Qiu
Recently, Harrow et al. [Phys. Rev. Lett. 92, 187901 (2004)] gave a method for preparing an arbitrary quantum state with high success probability by physically transmitting some qu…
Probabilistic cloning with supplementary information contained in the quantum states of two auxiliary systems
Lvjun Li, Daowen Qiu
In probabilistic cloning with two auxiliary systems, we consider and compare three different protocols for the success probabilities of cloning. We show that, in certain circumstan…
Decentralized Failure Diagnosis of Stochastic Discrete Event Systems
Fuchun Liu, Daowen Qiu, Hongyan Xing +1
Recently, the diagnosability of {\it stochastic discrete event systems} (SDESs) was investigated in the literature, and, the failure diagnosis considered was {\it centralized}. In…
Supervisory Control of Fuzzy Discrete Event Systems: A Formal Approach
Daowen Qiu
Fuzzy {\it discrete event systems} (DESs) were proposed recently by Lin and Ying [19], which may better cope with the real-world problems with fuzziness, impreciseness, and subject…
Diagnosability of Fuzzy Discrete Event Systems
Fuchun Liu, Daowen Qiu, Hongyan Xing +1
In order to more effectively cope with the real-world problems of vagueness, {\it fuzzy discrete event systems} (FDESs) were proposed recently, and the supervisory control theory o…
Fuzzy Discrete Event Systems under Fuzzy Observability and a test-algorithm
Daowen Qiu, Fuchun Liu
In order to more effectively cope with the real-world problems of vagueness, impreciseness, and subjectivity, fuzzy discrete event systems (FDESs) were proposed recently. Notably,…
