Entangledtila

Entangledtila is a hypothetical concept in quantum information theory describing a class of many-body quantum states whose entanglement is organized by a tiling pattern on a lattice. The term blends entanglement with a tiling structure, capturing how correlations are distributed across spatial regions.

Definition: Let L be a lattice and T a partition of L into tiles. Each tile t contains a set of subsystems. A state |Ψ⟩ on H = ⊗_v H_v is called an entangledtila state if (1) within each tile, subsystems exhibit strong, resource-like entanglement (for example, a cluster- or stabilizer-type state), and (2) inter-tile entanglement is constrained by the tiling, so that correlations across tile boundaries follow a prescribed pattern.

Properties: Entangledtilas can be described by tensor-network representations that reflect the tile layout. Refining the tiling, merging tiles, or changing tile boundaries can alter the global entanglement without changing local tile content. The framework supports both short-range and tailored long-range correlations, depending on the chosen tile interactions.

Examples: A simple lattice partition into four tiles, each hosting a maximally entangled pair, with modest entanglement connecting neighboring tiles, yields a basic entangledtila toy model. More complex arrangements use stabilizer codes or projected entangled pair states aligned to the tile grid.

Applications: The concept serves as a tool in exploring structured entanglement for quantum error correction, modular quantum memories, and tensor-network models of holography.

History: Entangledtila originated in theoretical discussions of patterned entanglement. It remains an abstract construct used to study how tiling-inspired organization of subsystems shapes global quantum correlations.
