Right, but how can one find the admin's email address if that webpage is
invisible to one's IPv6-only computer?  Maybe someone with an IPv4
computer can help to find the admin's email address, otherwise it is a 
chicken and egg problem.

Once the frontend is put on IP (IPv6) then one can try to figure out the 
addressing architecture for connecting the quantum computers to the
Internet, hence a certain view of the Quantum Internet.

It might be that the access control (login page) to the quantum
experience must be on IPv4, then the IBM Q classical cloud (frontend?)
could be on IP (IPv6), and then the attached quantum co-processor might
be again on IPv4, or on serial with ptp addressing, I dont know.

These are  unknowns, but might be very simple to find out.  They are
much simpler than the hard computing problems that quantum computing
might solve, or than the future quantum interconnects, but solving these
simple addressing problems might contribute to building a Quantum
Internet, or certain aspects of it.
