    "Erasing 1 bit of information dissipates at minimum k_B·T·ln(2) as heat. This sets a floor on the energy cost of any computation — including neural computation. A human brain processes ~10¹⁶ synaptic operations per second at ~20W, achieving ~10⁻¹⁶ J/operation — within a factor of 10³ of the Landauer limit at body temperature. Evolution couldn't exceed Landauer's bound because it's a thermodynamic theorem, not an engineering constraint. The same limit governs the energy efficiency of every computer, neural network accelerator, and future quantum processor. Consciousness is subject to the second law of thermodynamics.",

chain("Holevo Bound → Classical Information from Quantum Systems → Quantum Advantage",
    "The Holevo bound χ ≤ S(ρ) − Σ p_i·S(ρ_i) limits the classical information extractable from a qubit to at most 1 bit — even though the qubit's Hilbert space is infinite-dimensional. This is the fundamental ceiling on quantum communication, the security proof for quantum key distribution, and the reason Shor's algorithm works: it operates on the full Hilbert space WITHOUT extracting all the classical information, collapsing only what's needed. The same Holevo bound governs how much information any physical system — biological, engineered, or cosmological — can encode about its past. It is a theorem, not a hypothesis.",
