>>"As far as I can make out David Deutsch started Quantum Computation to be able to have a quantum observer to probe the nature of quantum reality."
That's very surprising to me, because Deutsch is heavily in the Everett interpretation branch of possible quantum interpretations (pun intended).
So, he doesn't need any wave-function-collapse magic to explain quantum mechanics.
>>"Remember that quantum theorists have a strange dog in the race due to the whole wave-function-collapse by an observer thing."
That's very insightful.

He considers a working QC as basically an experimental confirmation of the many-worlds interpretation. Something like: "So tell me, these amazing parallel computations - where exactly do you say that they are being computed again if not in the parallel worlds?" There is a nice interview with him in Wired that touches this briefly: https://www.wired.com/2007/02/the-father-of-quantum-computing/ https://www.wired.com/2007/02/the-father-of-quantum-computin... Check his answer to: "So what prompted you to start thinking about quantum computing?" My take is that for him the QC started as a thought experiment to get a quantum observer to sidestep the whole wavefunction collapse by a classical observer problem. >> That's very insightful. Thanks.
