and graphics. (viz: nVidia's CUDA, AMD's Stream, cross-platform OpenCL). lot of graphics cards out there. and tv sets. and audio gear. and medical imaging. spread it out onto signal transforms (fourier, laplace, etc.) in general, and you've got all the telecoms and networking (multiplexing, channel bonding). Big Data. Finance/HFT. (and don't mind that Internet thing, it's just a fad...)
... more or less, anything with FPGA in it.
basically, as long as the underlying applied computational algorithms can be parallelized, QC is extraordinarily useful.
