      Interest in quantum computing is often justified by faster-than-classical quantum algorithms. But in classical computing, algorithms are just a small part of the picture. Interfaces are (at least) as important, for instance. What would a better-than-classical-interface look like?

      This is an idle thought that occasionally pops into my head. I often am struck that so many arguments for QC are based on efficiency and similar concerns. Yet in conventional computing, that's just a tiny piece of the overall picture.

          I guess it is the sign of a hyped domain, similar to BlockChains over the past year+. It is a common trend when the actual usable working product / device / demo is now where close to being available... Only then do we become occupied with 'mandain' issues such as UI design...

          It's been true for as long as I've been interested in quantum computing (i.e., since 1992).

          Potential revolutionary speedups are a simple way to get people interested in something that doesn't exist yet. if they ever build useful quantum computers the field should broaden out and become more like normal engineering or computer science.

          I've always imagined that quantum computers would be used as co-processors, like the GPUs and Xeon Phis of today, rather than (say) replacing a laptop. Shor's factorisation algorithm, for instance, ricochets between a classical routine and a quantum subroutine (1/1)

          \x7f \x7f 2). The similarities continue: the CUDA runtime compiles code on the host and submits it to the GPU. Analogously, a classical CPU could compile a sequence of quantum gates, submit them to the quantum coprocessor, and verify the correctness of the computation (2/2).

          On the other hand, an extremely slow computer (like a human) is qualitatively different from a fast computer. Scaling matters at some point.

          Like code readability and maintainability; there are people who work on more intuitive ways to specify quantum algorithms but not at all in the same way that people who do research on software engineering.

          Sure, now that conventional computing is mature, but 30/40/50 years ago efficiency was a much bigger selling point.

          Also, I guess you would like to see a significant level of interaction from both sides? Hard to quantify this, but I mean not just copy pasting information, or blindly receiving orders?
