catena-Poly[(dichloridocadmium)-di-μ-chlorido-[bis­(morpholinium-κO)cadmium]-di-μ-chlorido]

In the title compound, [Cd2Cl6(C4H10NO)2]n, the coordination geometry of each CdII ion is distorted octa­hedral, but with quite different coordination environments. One CdII atom is coordinated by four Cl atoms and two O atoms from two morpholinium ligands, while the other is coordinated by six Cl atoms. Adjacent CdII atoms are inter­connected alternately by paired chloride bridges, generating a chain parallel to the a axis. Inter­chain N—H⋯Cl inter­actions form a two-dimensional network

Quantum steering for continuous variable in de Sitter space

We study the distribution of quantum steerability for continuous variables between two causally disconnected open charts in de Sitter space. It is shown that quantum steerability suffers from "sudden death" in de Sitter space, which is quite different from the behaviors of entanglement and discord because the latter always survives and the former vanishes only in the limit of infinite curvature. In addition, we find that the attainment of maximal steerability asymmetry indicates a transition between unidirectional steerable and bidirectional steerable. Unlike in the flat space, the asymmetry of quantum steerability can be completely destroyed in the limit of infinite curvature for the conformal and massless scalar fields in de Sitter space.Comment: 22 pages, 7 figure
