    • note
    • Since in this paper we are interested in comparing how different systems use physical resources, we use the term quantum computer for any physical system that has the required Hilbert-space dimension, and we reserve the term scalable quantum computer for systems that can provide the required Hilbert-space dimension efficiently.

    • note
    • Grover's algorithm does not fit into our resource discussion because it does not provide an exponential speed-up relative to classical algorithms. Nonetheless, the experiment in Ref. 35 illustrates the resource demands that come with using classical waves.

    • note
    • C. A. Fuchs has promoted the notion that Hilbert-space dimension is a "characteristic property" of a quantum system, arXiv. org e-print quant-ph/0204146, or perhaps an "element of reality," arXiv.org e-print quant-ph/0205039, which might be the realistic core of quantum theory.
