Suppose we build a universal quantum computer and it functions as we currently expect it to. Is there any reason to suggest that, beyond its uses for things like cryptography and quantum system simulation, such a device could be used to shed light on the measurement problem?
- As we scale up the modeling of quantum systems, from simple to dynamic and complex, can we test whether or not the apparent randomness of a decoherence event is due to our current inability/unwillingness to model the entirety of the system (particle, measurement apparatus, observer) in quantum terms?
(I used a universal quantum computer in my question, but if another kind of quantum computation device is more appropriate or preferred, then please tell me/answer in that spirit.)
N.B.1. I do not mean that a universal quantum computer can ever give us perfect information, or that we can provide it with perfect information, or that it can/will violate the Heisenberg uncertainty principle in terms of what it tells us. I am only asking in the context of decoherence.
N.B.2. I do not ask this in the context of a hidden variable theory; I am asking if our ignorance is based on our inability to efficiently process the description that we do have, rather than having an incomplete description to start with. If this distinction is not correct, or is not actually meaningful, then I have misunderstood it and will edit the question.
