Inadequacy of Modal Logic in Quantum Settings [PDF]

Electronic Proceedings in Theoretical Computer Science, 2019
We test the principles of classical modal logic in fully quantum settings. Modal logic models our reasoning in multi-agent problems, and allows us to solve puzzles like the muddy children paradox.

Implementation of Grover’s Algorithm & Bernstein-Vazirani Algorithm with IBM Qiskit

Journal of Informatics and Web Engineering
Quantum logic gates differ from classical logic gates as the former involves quantum operators. The conventional gates such as AND, OR, NOT etc., are generally classified as classical gates, however, some of the quantum gates are known as Pauli gates ...

Sequent Calculi for Orthologic with Strict Implication

Bulletin of the Section of Logic, 2022
In this study, new sequent calculi for a minimal quantum logic (\(\bf MQL\)) are discussed that involve an implication. The sequent calculus \(\bf GO\) for \(\bf MQL\) was established by Nishimura, and it is complete with respect to ortho-models (O ...

Quantum Logic and Quantum Reconstruction [PDF]

Foundations of Physics, 2015
Quantum logic understood as a reconstruction program had real successes and genuine limitations. This paper offers a synopsis of both and suggests a way of seeing quantum logic in a larger, still thriving context.

Connecting the free energy principle with quantum cognition

Frontiers in Neurorobotics, 2022
It appears that the free energy minimization principle conflicts with quantum cognition since the former adheres to a restricted view based on experience while the latter allows deviations from such a restricted view.

Quantum-Inspired Uncertainty Quantification

Frontiers in Computer Science, 2022
Reasonable quantification of uncertainty is a major issue of cognitive infocommunications, and logic is a backbone for successful communication. Here, an axiomatic approach to quantum logic, which highlights similarity to and differences to classical ...

Embedded Ferroelectric Nanoclusters Can Drive Polarization Reversal in a Non‐Ferroelectric Polar Film via the Proximity Effect

Advanced Functional Materials, EarlyView.
Ferroelectric nanoclusters create local internal fields in a normally non‐switchable polar film because of polarization mismatch at their interfaces. That field opposes polarization in the regions with larger polarization and reinforces polarization in the regions with smaller polarization.

Quantum logic automata generalizing the edge of chaos in complex systems

Frontiers in Complex Systems
BackgroundHistorically, although researchers in the science of complex systems proposed the idea of the edge of chaos and/or self-organized criticality as the essential feature of complex organization, they were not able to generalize this concept ...

Paths of Cultural Systems

Entropy, 2017
A theory of cultural structures predicts the objects observed by anthropologists. We here define those which use kinship relationships to define systems.

Quantum logic is undecidable [PDF]

Archive for Mathematical Logic, 2020
We investigate the first-order theory of closed subspaces of complex Hilbert spaces in the signature $(\lor,\perp,0,1)$, where `$\perp$' is the orthogonality relation. Our main result is that already its quasi-identities are undecidable: there is no algorithm to decide whether an implication between equations and orthogonality relations implies another
