Default work in QC points to screwy nature of reality

The reality indicated by Relativity is also weird.
In the theory time is "just another dimension" leading to
the concept of a frozen Bloch Universe.
In w auniverse where nothing really changes we are lost trying to
define how anything is reembered. How do we remember yesterday?
The obvious solution is weird -- the universe is like a frozen
aquarium but our minds are not part of it; they must be outside
and our attention is simply directed to different parts of the fish tank
from time to time.
A similar view can be argued from GP also -- the "base states" of
a quantum system are immutable; only the wave function changes.
But the wave function therefore can't be part of any base states or
even be a distributed between base states. The only way it can evolve
if the wave function of the universe is outside the universe.
(Maybe down a new 5th+ dimension that is the "real" direction of time).
Anyway, different scientists have different ideas.

Quantum computers are revealing an unexpected new theory of reality

A powerful new idea about how the laws of physics work could bring
breakthroughs on everything from quantum gravity to consciousness,
says researcher Chiara Marletto

"QUANTUM supremacy" is a phrase that has been in the news a lot
lately. Several labs worldwide have already claimed to have reached
this milestone, at which computers exploiting the wondrous features of
the quantum world solve a problem faster than a conventional classical
computer feasibly could. Although we aren't quite there yet, a
general-purpose "universal" quantum computer seems closer than ever â
a revolutionary development for how we communicate and encrypt data,
for virtual reality, artificial intelligence and much more.

These prospects excite me as a theoretical physicist too, but my
colleagues and I are captivated by an even bigger picture. The quantum
theory of computation originated as a way to deepen our understanding
of quantum theory, our fundamental theory of physical reality. By
applying the principles we have learned more broadly, we think we are
beginning to see the outline of a radical new way to construct laws of nature.

It means abandoning the idea of physics as the science of what's
actually happening, and embracing it as the science of what might or
might not happen. This "science of can and can't" could help us tackle
some of the big questions that conventional physics has tried and
failed to get to grips with, from delivering an exact, unifying theory
of thermodynamics and information to getting round conceptual barriers
that stop us merging quantum theory with general relativity,
Einstein's theory of gravity. It might go even further and help us to
understand how intelligent thought works, and kick-start a
technological revolution that would make quantum supremacy look modest
by comparison. ...
