    "abstract": "The primary resource for quantum computation is Hilbert-space dimension.\nWhereas Hilbert space itself is an abstract construction, the number of\ndimensions available to a system is a physical quantity that requires physical\nresources. Avoiding a demand for an exponential amount of these resources\nplaces a fundamental constraint on the systems that are suitable for scalable\nquantum computation. To be scalable, the effective number of degrees of freedom\nin the computer must grow nearly linearly with the number of qubits in an\nequivalent qubit-based quantum computer.",
