Bitcoin, and digital money, will need quantum encryption. Some of them
can be failed, but only in theory. Well, the last time I readon on
this, but the filed is exploding.
I guess that *classical* teleportation will needs quantum encryption
too, if you want avoid to be reconstituted by some Eve (by some
Eavesdroppers).
I would not say "yes" to a "doctor" without some guaranties my "Gödel
number" is enough secure.
I predict that the amount of digital communication used in encryption
will ever go up. Already bitcoin is very demanding, and virtual money
might become a danger for the climate. Some estimates that the
Internet is responsible already of 15% of the mundial pollution, ...
Now, Quantum computations will have many applications different from
encryption. To make the MW valid (original goal of Deutsch), to "find
a needle in a stack", to factorize big numbers (with other goal than
encryption (say), etc. but the main non-encryption goal will be to
simulated nature's phenomena, from protein foldings to black hole, to
big-bang(s), etc.

Any potential for this technology to go beyond Bitcoin or encryption
applications, JC? Specifically, the impact upon technological
innovation. Or do you feel, this is a pipe-dream, a bridge, too far?

Subject: Quantum Supremacy
For the first time a Quantum Computer has solved a problem that a
conventional computer can not, actually 2 different Quantum
Computers did and there is a paper from each team in the issue of
the journal Nature that came out yesterday:

They used their computers to simulate a quantum system, the
particular problem they solved is not very useful but the
implications are enormous, it proves once and for all that a
practical quantum computer that you can actually build can solve
problems that a conventional computer can't.
If I place 20 magnetized atoms in a lattice and then move one of
those atoms how will the entire array move in response? A good home
computer could solve that problem but the difficulty increases
exponentially as the number of atoms increases, when you get to
about 50 atoms even the largest supercomputer on Earth starts to beg
for mercy, but in the new reports one quantum computer solved the 51
atom problem and the other solved 53. The mechanical details of the
2 machines are different, one used very tightly focused LASER beams
and rubidium atoms and the other used electrically charged ytterbium
ions, but they both got the job done.
None of this is a threat to bitcoin....YET. But the clock is ticking.
