Sublattices in Quantum Logic

Definition

Sublattices in quantum logic refer to specific subsets of a lattice structure that maintain the properties of a lattice under the operations of meet and join, particularly within the framework of quantum mechanics. These structures help in understanding the logical relationships between quantum propositions, allowing for the exploration of how these propositions interact in a non-classical way, reflecting the unique nature of quantum systems.
