Physics-Based Approaches to Universal Atomic-Precision Replication: Thermodynamic and Manufacturing Perspectives

This study develops a physics-based framework for universal atomic-precision replication.It integrates thermodynamic limits, quantum-information constraints, and advanced manufacturing concepts.Using the Landauer principle, we estimate the minimum information energy for replicating a 0.2 kg fruit-like object at ~10⁻¹⁰ J, while realistic chemical and mechanical work requirements increase this by six to eight orders of magnitude.We show that macroscopic replication is consistent with known physics, though the quantum no-cloning theorem forbids perfect duplication of unknown quantum states.We propose an architecture combining high-resolution scanning, atomic-precision assembly, and bioreactor subsystems, offering measurable engineering targets for future nanofabrication and circular economy applications. contact [e-mail]
