摘要
Digital computers implement computations using circuits, as do many naturally occurring systems (e.g., gene regulatory 網絡s). The topology of any such circuit restricts which variables may be physically coupled during the operation of the circuit. We investigate how such restrictions on the physical coupling affects the 熱力學 costs of running the circuit. To do this we first calculate the minimal additional 熵 production that arises when we run a given gate in a circuit. We then build on this calculation, to analyze how the 熱力學 costs of implementing a computation with a full circuit, comprising multiple connected gates, depends on the topology of that circuit. This analysis provides a rich new set of optimization problems that must be addressed by any designer of a circuit, if they wish to min
