题目：定量化量子信道的纠缠

摘要：In the framework of resource theory of quantum channel, we present three new entanglement measures of channels for a quantum system of arbitrary finite dimension, based on the Choi relative entropy of channels, concurrence and k-ME concurrence, respectively. Rigorous proofs show that these proposed measures fulfill all the requirements dictated by the resource theory of quantum channels, including nonnegativity, weak monotonicity, strong monotone, convexity, additivity, and subadditivity. By using the measure, we describe the probability that the initial hypothesis is true in the hypothesis testing of channels. Comparing with other known measures of the quantum channels, these measures have obvious advantage in computability. According to the power of generating entanglement, we give a classification of quantum channels. Moreover, we provide several examples that characterize the properties of quantum channels and the conversions between quantum coherence states and entangled states and between fully separable states and multipartite entangled states.

题目：多体量子系统的最佳化局域测量基

摘要：We investigate optimization of dichotomic local phase measurement settings for multipartite quantum systems. We first describe a method of constructing a single multipartite Bell inequality by treating correlation function as an $n$-index tensor. Under a set of local phase measurement settings, we calculate quantum prediction of generalized Greenberger-Horne-Zeilinger state and show the exact relationship between quantum prediction and the phase factors. We show that there exists a set of optimal measurement settings relevant to maximal quantum prediction, which can contribute to testing multipartite Bell inequality in a straightforward manner. Also, we provide quantum simulation and numerical analysis with these optimal measurement settings.

题目：Quantum discord for multiqubit systems

摘要：We evaluate analytically the quantum discord for a large family of multiqubit states. It is interesting to note that the quantum discord of three qubits and five qubits is the same, as is the quantum discord of two qubits and six qubits. We discover that the quantum discord of this family of states can be classified into three categories. The level surfaces of the quantum discord in the three categories are shown through images. Furthermore, we investigated the dynamic behavior of quantum discord under decoherence. For the odd partite systems, we prove the frozen phenomenon of quantum discord does not exist under the phase flip channel, while it can be found in the even partite systems.

题目：Quantum integrable systems and universal characters

摘要：Universal character is one kind of extensions on Schur functions. As an extension on Kadomtsev-Petviashvili(KP) hierarchy, a hierarchy called universal character (UC) hierarchy was constructed. This UC hierarchy has a close connection with quantum integrable systems such as phase model, q-boson model and the topological string theory.

题目：The characterization of the superposable states set for a known state

摘要：The existence of superposition state is one of the most fundamental reasons why the quantum en- vironment is different from the classical field. However, there is no physically workable operation to superimpose random two unknown states with non-zero probability. We consider the superposition problem of qubit systems about unknown states and a known state, shown that the superposable states set for a known state in terms of trace-nonincreasing completely positive(CP) operation be located on a circle on the Bloch sphere, and any states of a circle on the Bloch sphere are super- posable for a fixed state. Finally, in the high-dimensional case, we explained that any superposition transformation protocol by CP operation will violate no-cloning principle in almost all states, our results maybe promote a deeper understanding and application of the superposition principle.

题目：Complementary Relations Between Coherence and Mixedness

摘要： As an important resource, the quantum coherence is one of the fundamental features of the quantum world. It is essential to understand the relationship between the resource and the mixedness of an open quantum system. We present complementary relations between the coherence measures (coherence via skew information, geometric measure of coherence, l2 norm of coherence, lp (1≤p<2) norm of coherence and the mixedness (normalized linear entropy mixedness, geometric measure of mixedness, mixedness via skew information). The evolution of these complementary relations are also investigated under the bit flip, phase flip, depolarizing and amplitude damping channels. Our results include some existing conclusions as special cases.
