چکیده
The entanglement of graph states up to eight qubits is calculated in the regime of iteration calculation. The entanglement measures could be the relative entropy of entanglement, the logarithmic robustness or the geometric measure. All 146 local inequivalent graphs are classified as three categories: the 2-colorable graphs, the non 2colorable graphs with identical upper LOCC entanglement bound and lower bipartite entanglement bound, the non 2-colorable graphs with unequal bounds. The last may displays non-integer entanglement. The precision of iteration calculation of the entanglement is less than 10−14. PACS number(s): 03.67.Mn, 03.65.Ud, 02.10.Ox Keyword(s): graph state; iteration; multipartite entanglement

We study the dephasing of a single qubit coupled to a bosonic bath. In particular, we investigate the case when the bath is initially prepared in a pure state known as the Schrödinger cat. In clear contradistinction to the time-evolution of an initial coherent state, the time evolutions of the purity and the coherence factor now depend on the particular choice of the Schrödinger cat state. We a...

Precise definitions of “weak [quantum] measurements” and “weak value” [of a quantum observable] are offered, which seem to capture the meaning of the often vague ways that these terms are used in the literature. Simple finite dimensional examples are given showing that weak values are not unique. They therefore cannot correspond to any physical attribute of the system being “weakly” measured, c...

Abstract. A method of constructing n × n matrix solutions(with n matrix elements) of Temperley-Lieb algebra relation is presented in this paper. The single loop of these solutions are d = √ n. Especially, a 9×9−matrix solution with single loop d= √ 3 is discussed in detail. An unitary Yang-Baxter R̆(θ, q1, q2) matrix is obtained via the Yang-Baxterization process. The entanglement property and g...
