Machian Origin of the Entropic Gravity and Cosmic Acceleration
Merab Gogberashvili, Igor Kanatchikov
We discuss the emergence of relativistic effects in the Machian universe with a global preferred frame and use thermodynamic considerations to clarify the origin of gravity as an e…
Reexamination of determinant-based separability test for two qubits
Maciej Demianowicz
It was shown in [Augusiak et al.,\;Phys. Rev. A \textbf{77}, 030301(R) (2008)] that discrimination between entanglement and separability in a two qubit state can be achieved by a m…
On structural physical approximations and entanglement breaking maps
Remigiusz Augusiak, Joonwoo Bae, Łukasz Czekaj +1
Very recently a conjecture saying that the so-called structural physical approximations (SPAa) to optimal positive maps (optimal entanglement witnesses) give entanglement breaking…
Efficient bounds on quantum communication rates via their reduced variants
Marcin L. Nowakowski, Pawel Horodecki
We investigate one-way communication scenarios where Bob manipulating on his parts can transfer some sub-system to the environment. We define reduced versions of quantum communicat…
Violation of Clauser-Horne-Shimony-Holt inequality for states resulting from entanglement swapping
Antoni Wojcik, Joanna Modlawska, Andrzej Grudka +1
We consider violation of CHSH inequality for states before and after entanglement swapping. We present a pair of initial states which do not violate CHSH inequality however the fin…
Two-spinors, oscillator algebras, and qubits: Aspects of manifestly covariant approach to relativistic quantum information
Marek Czachor
The first part of the paper reviews applications of 2-spinor methods to relativistic qubits (analogies between tetrads in Minkowski space and 2-qubit states, qubits defined by mean…
