Exploring Imprecise Probabilities in Quantum Algorithms with Possibility Theory

open access: yesProceedings in Applied Mathematics and Mechanics, Volume 26, Issue 1, March 2026.
ABSTRACT Quantum computing utilizes the underlying principles of quantum mechanics to perform computations with unmatched performance capabilities. Rather than using classical bits, it operates on qubits, which can exist in superposition and entangled states. This enables the solution of problems that are considered intractable for classical computers.

A Re‐Examination of Foundational Elements of Cosmology

open access: yesFortschritte der Physik, Volume 74, Issue 3, March 2026.
ABSTRACT This paper undertakes a conceptual re‐examination of several foundational elements of cosmology through the lens of spacetime symmetries. A new derivation of the Friedmann–Lemaître–Robertson–Walker metric is obtained by a careful conceptual examination of rotations and translations on generic manifolds, followed by solving the rotational and ...

Digital Twin Simulations Toolbox of the Nitrogen‐Vacancy Center in Diamond

open access: yesAdvanced Quantum Technologies, Volume 9, Issue 3, March 2026.
The Nitrogen‐vacancy (NV) center in diamond is a key platform within quantum technologies. This work introduces a Python based digital‐twin of the NV, where the spin dynamics of the system is simulated without relying on commonly used approximations, such as the adoption of rotating frame. The digital‐twin is validated through three different examples,

Disentanglement by Deranking and by Suppression of Correlation

open access: yesAdvanced Quantum Technologies, Volume 9, Issue 3, March 2026.
ABSTRACT The spontaneous disentanglement hypothesis is motivated by some outstanding issues in standard quantum mechanics, including the problem of quantum measurement. The current study compares between some possible methods that can be used to implement the hypothesis.

The Douglas Lemma for von Neumann Algebras and Some Applications

open access: yes, 2017
In this article, we discuss the well-known Douglas lemma on the relationship between majorization and factorization of operators, in the context of von Neumann algebras. We give a proof of the Douglas lemma for von Neumann algebras which is essential for

A Stacking Ensemble Model for Specific Yield Prediction: Framework Development and Application to Groundwater Storage Change Estimation in the North China Plain

open access: yesWater Resources Research, Volume 62, Issue 3, March 2026.
Abstract Specific yield (SY) is a key parameter in estimating groundwater storage change. Accurately predicting SY in unconfined aquifers remains challenging, as SY varies with groundwater‐level fluctuations and unsaturated‐zone moisture fluxes. This challenge is particularly evident in the North China Plain (NCP), which has experienced substantial ...

On Birkhoff – James and Roberts orthogonality

open access: yesSpecial Matrices, 2018
In this paper we present some recent results on characterizations of the Birkhoff-James and the Roberts orthogonality in C*-algebras and Hilbert C*-modules.

On quantum ergodicity for higher‐dimensional cat maps modulo prime powers

open access: yesBulletin of the London Mathematical Society, Volume 58, Issue 3, March 2026.
Abstract A discrete model of quantum ergodicity of linear maps generated by symplectic matrices A∈Sp(2d,Z)$A \in \operatorname{Sp}(2d,{\mathbb {Z}})$ modulo an integer N⩾1$N\geqslant 1$, has been studied for d=1$d=1$ and almost all N$N$ by Kurlberg and Rudnick (2001, Comm. Math. Phys., 222, 201–227).

Matrix algebraic sets of infinite dimension [PDF]

open access: yesМатематичні Студії, 2012
Using multiplicative polynomials on algebras it is proved an analogue of Hilbert Nullstellensatz for the case of an infinite-dimensional real Banach space.
