  "abstract": "We introduce the thermodynamic wall: a boundary-condition formulation of the trade-off between macroscopic heat dissipation and quantum coherence time in engineered systems. Just as computational wall models in fluid dynamics encode unresolved near-boundary physics into an enriched boundary treatment, the thermodynamic wall encodes an unresolved thermal environment into an effective boundary object that imposes a flux constraint on any quantum device embedded behind it. We develop the framework in two regimes. In the macroscopic regime, a room-temperature insulating wall (k=0.04 mathrmW m^-1K^-1, A=10 mathrmm², Δ T=30 K, d=0.1 m) dissipates P=1.20×10² W and, under a linear-decoherence coupling hypothesis, yields a characteristic energy-per-flux time τ=Δ E/P=1.125×10⁴ s≈3.13 h.
