Role of matter coherence in entanglement due to gravity [PDF]
Quantum, 2022 We investigate the quantum nature of gravity in terms of the coherence of quantum objects. As a basic setting, we consider two gravitating objects each in a superposition state of two paths.

Completely positive map from M4(C) to M5(C) on positive semidefinite Matrices [PDF]
, 2022 Positive maps are essential in the description of quantum systems. However, characterization of the structure of the set of all positive maps is a challenge in mathematics and mathematical physics.

The Crossed Product of Finite Hopf C*-Algebra and C*-Algebra
Mathematics, 2021 Let H be a finite Hopf C*-algebra and A a C*-algebra of finite dimension. In this paper, we focus on the crossed product A⋊H arising from the action of H on A, which is a ∗-algebra.

Guaranteeing Completely Positive Quantum Evolution [PDF]
, 2022 In open quantum systems, it is known that if the system and environment are in a product state, the evolution of the system is given by a linear completely positive (CP) Hermitian map.

A note on Radon-Nikodým derivatives and similarity for completely bounded maps [PDF]
Opuscula Mathematica, 2009 We point out a relation between the Arveson's Radon-Nikodým derivative and known similarity results for completely bounded maps. We also consider Jordan type decompositions coming out from Wittstock's Decomposition Theorem and illustrate, by an example ...

Mapping groundwater vulnerability using drastic method [PDF]
E3S Web of Conferences, 2023 Preventive management and protection of groundwater were to create a groundwater vulnerability map. This map provided information distribution on the level of vulnerability to groundwater contamination in an area.

Completely positive quantum trajectories with applications to quantum state smoothing [PDF]
, 2020 To compare quantum estimation theory schemes we must acknowledge that, in some cases, the quantitative difference between them might be small and hence sensitive to numerical errors.

On the Debate Concerning the Proper Characterisation of Quantum Dynamical Evolution [PDF]
, 2012 There has been a long-standing and sometimes passionate debate between physicists over whether a dynamical framework for quantum systems should incorporate not completely positive (NCP) maps in addition to completely positive (CP) maps.
