A team has taken the first atomic-resolution images and demonstrated electrical control of a chiral interface state -- an exotic quantum phenomenon that could help
researchers advance quantum computing and energy-efficient electronics.

There's money in quantum computing, and everyone wants a part.
I'll stick my neck out and state that there willl never be a
general-purpose quantum computer.

I'll concede that it *is* possible to use quantum effects to
model or simulate certain processes: An analog computer, in
essence.

There. Prove me wrong.

I dunno, much of the 'quantum' hype is going back to the Copenhagen interpretation..
https://en.wikipedia.org/wiki/Copenhagen_interpretation
I never agreed with that.

All a bit vague.

And there is the 'photon' crap.
Sure you can, as mamaticians define 'photon' as an elementary particle (Albert the Stone Counter was into that IIRC)
but anybody who has ever worked with a PMT knows that is is just the energy that knocked an electron out of the target electrode.
and does not say anything about the stuff the waves that kicked it free are made of.
In a Le Sage theory in my interpretation these Le Sage particles, or a state of those, can be EM radiation
and are like the wave of water molecules that knock a ball connected with a wire to a pole in the ocean free
where the wire strength is the binding energy of the electron to a atom in the target electrode,
the ball example shows nothing about the waves other then a local magnitude and frequency, the water molecules are orders of magnitude smaller.
Nice TV thing today about the Higgs boson today
Fishysicks never seem to grasp basics.
Even Max Planck warned about using his constant in the wrong way, mamaticians think numbers are reality and work with incomplete equations and get stuck in multiple universes..
What not
The other link I gave with nano-bolometers will likely do better
But the feeling I get is poor kids getting hammered by Albert's crap going in circles
hammered into obedience by their peers.
Maybe some generations need to pass before a better view is accepted.

No I am not holding my breath for a big kwantuum computah in the shops.
And 4 sure as far as 'uncrackable' goes, forget it
If they can break RSA 2048?
https://google.com/search?q=+crypto+broken+by+quantum+computer
better use some backdoor...

I'm inclined to agree. I think there might be the odd specialist one
that is purpose built to solve particular NP hard problems though. Most
obvious application is factoring huge primes that modern cryptography
relies upon. If such a device was ever built it would likely never
appear in the open literature much like Turing's Bombe and Collossus.
(at least not until half a century later maybe not even then)

It is a fair bit more than an analogue computer though.

There may also be ways to utilise chemistry to produce specific programs
to test certain types of combinatorial hypothesis with RNA/DNA and/or
amino acids which also relies to some extent on quantum comparisons.

I don't think it is a coincidence that RNA has four bases corresponding
to the 4-way branch of a quantum if statement (and amino acids ~20 corresponding to the maximum branch factor of 3 quantum comparisons).
