Quantum Lattice Framework Based on Molecular Functional Group Lattice for Room-Temperature Quantum Coherence

We propose a Quantum Lattice framework in which quantum dots (QDs) are coherently coupled via a molecular-scale lattice of functional groups such as amine (-NH₂) in polyethylenimine (PEI). The subwavelength molecular periodicity (~0.5 nm) and effective mesh spacing (~1–3 nm) provide a potential landscape enabling dipole–dipole coherence among quantum dots at room temperature. Density-functional-level analysis suggests that chemical bonding periodicity can serve as a phase-stabilizing field, potentially leading to collective coherence and superradiance without cryogenic confinement [1,2]. This conceptual model introduces a new paradigm of structural coherence engineering, merging quantum mechanics and molecular chemistry for ambient quantum devices.
