Comment on "Quantum Teleportation of Eight-Qubit State via Six-Qubit Cluster State"
Recently, Zhao et al., (Int. J. Theor. Phys. 57, 516-522 (2018)) have
proposed a scheme for quantum teleportation of an eight-qubit quantum state
using a six qubit cluster state. In this comment, it's shown that the quantum
resource (multi-partite entangled state used as the quantum channel) used by
Zhao et al., is excessively high and the task can be performed using any two
Bell states as the task can be reduced to the teleportation of an arbitrary two
qubit state. Further, a trivial conceptual mistake made by Zhao et al., in the
description of the quantum channel has been pointed out. It's also mentioned
that recently a trend of proposing teleportation schemes with excessively high
quantum resources has been observed and the essence of this comment is
applicable to all such proposals.Comment: It is shown that teleportation of multi qubit-states can be done
using Bell state

Testing creativity of dance students in the People's Republic of China
In the past decade there has been increasing concern over the losses that may accompany the benefits of dance training for young people (Abra, 1987/ 88; Brady, J., 1982; Gordon, S., 1983; Innes, 1988; Kirkland, G. with Lawrence, G., 1986; Schnitt, 1990; Stinson, Blumenfeld—Jones and Van Dyke, 1990). An investigation by Zhao Guo Wei (1989), educational psychologist at the Beijing Dance lnstitute, lends further support to these concerns
Recent Results from BES
We report partial wave analysis results for based
on BESI events, and find to be dominant in
the mass region. Some very preliminary results are presented from
the events newly collected at the upgraded
BES(BESII). Using the world largest data sample, BES measures
branching ratios of radiative and hadronic decays. The preliminary R
values measured by BESII in the 2-5 GeV energy region are also presented.Comment: 11 pages, 11 figures, proceeding paper for IV International
