Interesting results Bill.

If you are interested, you might try Deutsch's question on it. For example,
prompting it with something like:

------

"A quantum computer of 8000 qubits can, using Shor's algorithm, factor a
4000-bit number. This algorithm does so by using the qubits to represent
every number from 0 to 2^4000 - 1, and performing a distinct mathematical
calculation against each one to get a distinct result. Finally, it uses
interference to cancel out the wrong answers to produce a correct result.

My question is: how is it that the quantum computer can represent 2^4000
distinct numbers, and perform 2^4000 distinct computations as it performs
Shor's algorithm? Our universe only has some 2^260 atoms in it, there's not
enough atoms in the universe to represent all these values. So then, where
are all these numbers being represented? Where in reality are all these
computations being performed? They must be done somewhere given we get the
correct result, where are they all happening?

Please explain as best you can, answers to these questions assuming that
XXXXX is the correct description of quantum mechanics."

------


You could experiment having the AI answer this question in different
sessions but change XXXXX to different interpretations, such as:

"The Copenhagen Interpretation"
"Many-Worlds"
"Pilot-wave Theory"
"Quantum Bayesianism"


The great thing about AI is we can have it answer these questions, where
someone who believes in CI, for example, might refuse to answer or ignore
the question.
