The Demon's Hardware: Information-Geometric Bounds on Thermodynamic Computing

Key Points

• To establish information-geometric bounds on the energy costs of irreversible computation within thermodynamic systems.
• Derivation of lower bounds based on Fisher information geometry.
• Analysis of superconductor computing and extension to general thermodynamic architectures.
• Development of falsification conditions for quantum computing systems.
• Demonstrated that the Landauer limit is not applicable under opacity constraints.
• Established that opacity leads to a multiplicative energy penalty.
• Provided testable predictions for performance in quantum computing scenarios.
