  • Ying, Mingsheng; Feng, Yuan (Institute Of Electrical And Electronics Engineers, 2009)
    A classical circuit can be represented by a circuit graph or equivalently by a Boolean expression. The advantage of a circuit graph is that it can help us to obtain an intuitive understanding of the circuit under consideration, ...
  • Ying, Mingsheng; Feng, Yuan; Duan, Runyao; Ji, Zhengfeng (Association For Computing Machinery, 2009)
    We introduce an algebra qCCS of pure quantum processes in which communications by moving quantum states physically are allowed and computations are modeled by super-operators, but no classical data is explicitly involved. ...
  • Feng, Yuan; Duan, Runyao; Ying, Mingsheng (Assoc Computing Machinery, 2012)
    Quantum cryptographic systems have been commercially available, with a striking advantage over classical systems that their security and ability to detect the presence of eavesdropping are provable based on the principles ...
  • Feng, Yuan; Duan, Runyao; Ying, Mingsheng (IEEE-Inst Electrical Electronics Engineers Inc, 2005)
    We are concerned with catalyst-assisted probabilistic entanglement transformations. A necessary and sufficient condition is presented under which there exist partial catalysts that can increase the maximal transforming ...
  • Feng, Yuan; Shi, Yuquan (IEEE-Inst Electrical Electronics Engineers Inc, 2009)
    Bennett et al [Physical Review A, vol.59, no. 2, p. 1070, 1999] identified a set or orthogonal product states in the Hilbert space C-3 circle times C-3 such that reliably distinguishing those states requires nonlocal quantum ...
  • Ying, Mingsheng; Feng, Yuan (IEEE Computer Soc, 2011)
    Several high-level quantum programming languages have been proposed in the previous research. In this paper, we define a low-level flowchart language for quantum programming, which can be used in implementation of high-level ...
  • Feng, Yuan; Zhang, Shengyu; Duan, Runyao; Ying, Mingsheng (American Physical Soc, 2002)
    We derive a lower bound on the inconclusive probability of unambiguous discrimination among n linearly independent quantum states by using the constraint of no signaling. It improves the bound presented in the. paper of ...
  • Sun, Xiaoming; Zhang, Shengyu; Feng, Yuan; Ying, Mingsheng (American Physical Soc, 2002)
    Unambiguous discrimination is a strategy to the discrimination problem that identifies the state with certainty, leaving a possibility of undecidability. This paper points out that the optimal success probability of ...
  • Feng, Yuan; Yu, Nengkun; Ying, Mingsheng (Academic Press Inc Elsevier Science, 2013)
    Although security of quantum cryptography is provable based on principles of quantum mechanics, it can be compromised by flaws in the design of quantum protocols. So, it is indispensable to develop techniques for verifying ...
  • Ji, Zhengfeng; Wang, Guoming; Duan, Runyao; Feng, Yuan; Ying, Mingsheng (IEEE-Inst Electrical Electronics Engineers Inc, 2008)
    The efficiency of parameter estimation of quantum channels is studied in this paper. We introduce the concept of programmable parameters to the theory of estimation. It is found that programmable parameters obey the standard ...
  • Duan, Runyao; Feng, Yuan; Ying, Mingsheng (IEEE-Inst Electrical Electronics Engineers Inc, 2006)
    Suppose Alice and Bob try to transform an entangled state shared between them into another one by local operations and classical communications. Then in general a certain amount of entanglement contained in the initial ...
  • Feng, Yuan; Duan, Runyao; Ji, Zhengfeng; Ying, Mingsheng (Academic Press Inc Elsevier Science, 2007)
    Modeling and reasoning about concurrent quantum systems is very important for both distributed quantum computing and quantum protocol verification. As a consequence, a general framework formally describing communication ...
  • Feng, Yuan; Zhang, Shengyu; Ying, Mingsheng (American Physical Soc, 2002)
    We construct a probabilistic cloning and deleting machine which, taking several copies of an input quantum state, can output a linear superposition of multiple cloning and deleting states. Since the machine can perform ...
  • Feng, Yuan; Ying, Mingsheng (Science China Press, 2004)
    A reasonable transition rule is proposed for synchronized actions and some equational properties of bisimilarity and weak bisimilarity in the process algebra for reasoning about concurrent actions are presented.
  • Feng, Yuan; Duan, Runyao; Ji, Zhengfeng; Ying, Mingsheng (Elsevier Science Bv, 2007)
    We apply the notion of quantum predicate proposed by D'Hondt and Panangaden to analyze a simple language fragment which may describe the quantum part of a future quantum computer in Knill's architecture. The notion of ...
  • Ying, Mingsheng; Feng, Yuan (Springer-Verlag, 2010)
    Loop is a powerful program construct in classical computation, but its power is still not exploited fully in quantum computation. The exploitation of such power definitely requires a deep understanding of the mechanism of ...
  • Ying, Mingsheng; Feng, Yuan; Duan, Runyao; Li, Yangjia; Yu, Nengkun (Science Press, 2012)
    This paper surveys the new field of programming methodology and techniques for future quantum computers, including design of sequential and concurrent quantum programming languages, their semantics and implementations. ...
  • Feng, Yuan; Yu, Nengkun; Ying, Mingsheng (Springer, 2013)
    We introduce the notion of recursive quantum Markov chain (RQMC) for analysing recursive quantum programs with procedure calls. RQMCs are natural extension of Etessami and Yannakakis?s recursive Markov chains where the ...
  • Ying, Shenggang; Feng, Yuan; Yu, Nengkun; Ying, Mingsheng (Springer, 2013)
    This paper studies three kinds of long-term behaviour, namely reachability, repeated reachability and persistence, of quantum Markov chains (qMCs). As a stepping-stone, we introduce the notion of bottom strongly connected ...
  • Duan, Runyao; Ji, Zhengfeng; Feng, Yuan; Ying, Mingsheng (Springer, 2006)
    Quantum information theory is a new interdisciplinary research field related to quantum mechanics, computer science, information theory, and applied mathematics. It provides completely new paradigms to do information ...
