Many-agent controlled teleportation of multi-qubit quantum information
We present a general idea to construct methods for multi-qubit quantum
teleportation between two remote parties with control of many agents in the
network. Our methods seem to be much simpler than the existing method proposed
recently (Phys. Rev. A {\bf 70}, 022329(2004)). We then demonstrate our idea by
using several different protocols of quantum key distribution, including Ekert
91 and the deterministic secure communication protocol raised by Deng and Long.Comment: This paper has been accepted for publication in Phys. Lett.
Local Composite Quantile Regression for Regression Discontinuity
We introduce the local composite quantile regression (LCQR) to causal
inference in regression discontinuity (RD) designs. Kai et al. (2010) study the
efficiency property of LCQR, while we show that its nice boundary performance
translates to accurate estimation of treatment effects in RD under a variety of
data generating processes. Moreover, we propose a bias-corrected and standard
error-adjusted t-test for inference, which leads to confidence intervals with
good coverage probabilities. A bandwidth selector is also discussed. For
illustration, we conduct a simulation study and revisit a classic example from
Lee (2008). A companion R package rdcqr is developed
Multiparty Quantum Secret Sharing
Based on a quantum secure direct communication (QSDC) protocol [Phys. Rev.
A69(04)052319], we propose a -threshold scheme of multiparty quantum
secret sharing of classical messages (QSSCM) using only single photons. We take
advantage of this multiparty QSSCM scheme to establish a scheme of multiparty
secret sharing of quantum information (SSQI), in which only all quantum
information receivers collaborate can the original qubit be reconstructed. A
general idea is also proposed for constructing multiparty SSQI schemes from any
QSSCM scheme

[N,N,N′,N′-Tetrakis(benzimidazol-2-ylmethyl)ethane-1,2-diamine]copper(II) sulfate monohydrate
In the title compound, [Cu(C34H32N10)]SO4·H2O, the CuII ion is coordinated by six N atoms of a hexadentate N,N,N′,N′-tetrakis(benzimidazol-2-ylmethyl)ethane-1,2-diamine (EDTB) ligand, in a distorted octahedral environment. In the crystal structure, intermolecular N—H⋯O and weak C—H⋯O hydrogen bonds connect the cations, anions and water molecules into a three-dimensional network. The O atoms of the anion are disordered over two sites with refined occupancies of 0.711 (2) and 0.289 (2)
5-(Dimethylammonio)naphthalene-1-sulfonate dihydrate
There are two formula units in the asymmetric unit of the title compound, C12H13NO3S·2H2O. In the crystal structure, molecules are linked by intermolecular O—H⋯O, N—H⋯O and weak C—H⋯O hydrogen bonds, forming a three-dimensional network
