Enlargements of quantum logics [PDF]

open access: yesPacific Journal of Mathematics, 1988
Let K be a quantum logic whose state space is nonvoid. Let B be a Boolean algebra and let C be a compact convex subset of a locally convex topological linear space. Then K can be embedded into a logic L such that the centre of L equals B and the state space of L equals C.

Quantum Logic for Quantum Computers

open access: yesInternational Journal of Theoretical Physics, 2000
The following results obtained within a project of finding algebra of states in a general purpose quantum computer are reported: 1. all operations of an orthomodular lattice, including the identity, are five-fold defined ; 2. there are non-orthomodular models for both quantum and classical logics ; 3.

Classical Logic and Quantum Logic with Multiple and Common Lattice Models

open access: yesAdvances in Mathematical Physics, 2016
We consider a proper propositional quantum logic and show that it has multiple disjoint lattice models, only one of which is an orthomodular lattice (algebra) underlying Hilbert (quantum) space.

Quantum Fredkin and Toffoli gates on a versatile programmable silicon photonic chip

open access: yesnpj Quantum Information, 2022
Quantum logic gates are backbones of quantum information processing (QIP), wherein the typical three-qubit Fredkin and Toffoli gates are essential in quantum computation and communication.

Parametrical T-Gate for Joint Processing of Quantum and Classic Optoelectronic Signals

open access: yesJ, 2023
Unmanned network robotics is a new multidisciplinary field that involves many fields of computer networks, multi-agent systems, control theory, 5G and 6G Internet, computer security, and wireless quantum communications.

Compositional Quantum Logic [PDF]

open access: yes, 2013
Quantum logic aims to capture essential quantum mechanical structure in order-theoretic terms. The Achilles' heel of quantum logic is the absence of a canonical description of composite systems, given descriptions of their components. We introduce a framework in which order-theoretic structure comes with a primitive composition operation.

A Logic for Quantum Register Measurements

open access: yesAxioms, 2019
We know that quantum logics are the most prominent logical systems associated to the lattices of closed Hilbert subspaces. However, what happen if, following a quantum computing perspective, we want to associate a logic to the process of quantum ...

Universal fault-tolerant quantum computing with stabilizer codes

open access: yesPhysical Review Research, 2022
The quantum logic gates used in the design of a quantum computer should be both universal, meaning arbitrary quantum computations can be performed, and fault-tolerant, meaning the gates keep errors from cascading out of control.

Connecting the free energy principle with quantum cognition

open access: yesFrontiers 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.

Classical Logic in the Quantum Context

open access: yesQuantum Reports, 2020
It is generally accepted that quantum mechanics entails a revision of the classical propositional calculus as a consequence of its physical content. However, the universal claim according to which a new quantum logic is indispensable in order to model ...
