Chapter Four: Fire Above Absolute Zero

【My original processor,】 Mu-Zero said. 【And the third problem.】 The proposition asked whether a local rearrangement in a defective aperiodic lattice could perform information switching beneath the thermodynamic energy floor without exporting entropy to an outside observer. “Below the Landauer limit?” Xu said. “That is a perpetual-motion machine.” 【Landauer punishes erasure, not computation. The question is whether one can compute without forgetting.】 Metal shrieked above them. The intruders would breach the final door in twelve minutes. Ordinary chips erased the former state when turning zero into one. Reversible computation could approach zero dissipation, but defects retained path information.
