    "abstract": "If a quantum computer is stabilized by fault-tolerant quantum error\ncorrection (QEC), then most of its resources (qubits and operations) are\ndedicated to the extraction of error information. Analysis of this process\nleads to a set of central requirements for candidate computing devices, in\naddition to the basic ones of stable qubits and controllable gates and\nmeasurements. The logical structure of the extraction process has a natural\ngeometry and hierarchy of communication needs; a computer whose physical\narchitecture is designed to reflect this will be able to tolerate the most\nnoise. The relevant networks are dominated by quantum information transport,\ntherefore to assess a computing device it is necessary to characterize its\nability to transport quantum information, in addition to assessing the\nperformance of conditional logic on nearest neighbours and the passive\nstability of the memory. The transport distances involved in QEC networks are\nestimated, and it is found that a device relying on swap operations for\ninformation transport must have those operations an order of magnitude more\nprecise than the controlled gates of a device which can transport information\nat low cost.",
