Comp makes physics a first person plural reality, and a prioriwe might be able to exploit the first plural indeterminacy tocompute more function, like we know already that we have more"processes", like that free random oracle. The empirical fact thatquantum computer does not violate CT can make us doubt about this.I don't think that is so clear. Nielsen has written some papers oncomputations in QM that are not Turing emulable, essentially relyingon the fact that QM uses real numbers. He suggests that QM shouldbe restricted to avoid this kind of hypercomputation by dropping theassumption that all unitary operators are allowed.

`Yes. e^i * OMEGA *t is a solution of the SWE. With OMEGA = Chaitin's`

`incompressible real number. But are the real numbers "physically`

`real"? Open problem in comp, and in our "observable universe". Nielsen`

`is aware that, would we met such a quantum wave, we would be unable to`

`recognize it or to distinguish it from quantum noise. Which follows`

`from comp indeed.`

`More interestingly e^i * POST *t, with POST = Post "creative number",`

`which decimal codes the stopping problem, would be a quantum universal`

`dovetailer. Here the wave will have the computations redundancy`

`needed to give sense to the measure problem. With the incompressible`

`OMEGA you get a shallow description of all there is by doing a highly`

`But I am not sure that the decimals in the wave plays any relevant`

`stable realities configuration, and it is hard to avoid, logically,`
