While quantum computation has long been promised, and new scenarios and problems for it to tackle are being explored, at the moment we are short on scale. To define and understand the requirements of scale requires also knowing the needs of the problems to be solved.  And then, together with those requirements, working to define the desiderata of the system architecture.  I’ll describe what’s needed to scale as we know it today, and the quantum and classical technologies we believe will take us there.
