I think quantum computers are a big swindle.

Jeroen - We like to think of them as an open challenge and emerging opportunity - but you are right - it will take a lot of healthy skepticism and hard work to get down that long road before they are truly useful. If it's the road that matters to you, give us a call.

So I've heard, but why don't our brains need cryo cooling?

There is allegedly a web portal somewhere in ibm.com that lets you
upload code that runs on one of their machines, but maybe it's just a
simulator.

Yes, real machines and simulators both. You should expect to see more in the next few years, based on multiple platforms. Some don't even need cryogenics. Early days and and many small steps ahead, but the next couple years should see some good progress.

Quantum mechanics works at all temperatures.

The qbit cryo things are primitive, but the idea of finding solutions
by quantum superposition is too good for critters not to use.

But quantum states get perturbed very easily, and higher temperatures mean more frequent perturbations.

Those same critters that implemented error-detection and correction in the genetic code? It's clearly a good idea, but it doesn't seem to have happened either.

Only if you take one of Roger Penrose's sillier speculations seriously.

Have you noticed how no one ever truly explains how quantum
computers are supposed to work? I mean, we get plenty of this
"quantum bits have multiple states simultaneously" nonsense,
but that's just embezzlement. Awe and wonder, but no substance.

In the end, to get a usable result out of a quantum system,
you have to gather statistics, run many of them, or run one
many times or for a long time. That doesn't look very efficient
or scalable.

Oh, you can build gadgets based on quantum behaviour to solve
specific problems, but those would essentially only solve *that*
problem, nothing else. They would be akin to analog computers.

I think it's all just hype.

Actually, some people can.

There was a fad once for public demonstrations of people who could do
amazing math in their heads.

https://en.wikipedia.org/wiki/Mental_calculator

Some people can hit a ball flying at 100 MPH with a stick.

https://www.npr.org/2016/09/03/492516937/how-a-baseball-batters-brain-reacts-to-a-fast-pitch

450 milliseconds for a ballistic calculation, using wet chemical,
millisecond logic elements.

I knew a guy who would look at the seams on an incoming tennis ball to
learn its spin, so he could factor that into his return english. That
process took a fraction of a second.

I played table tennis with the world's 16th best player. Of course I
couldn't return a single shot. That's even faster than tennis.

I analyze thousands, or maybe trillions, of possible electronic
circuits in parallel, sometimes in my sleep.

There have been published algorithms for quantum computers for yonks.

I did a bit of work with the IBM quantum computing group about a dozen
years ago--David di Vincenzo (the local quantum computing theory guru)
and I came up with a scheme for using my antenna-coupled tunnel
junctions and Roger Koch's superconducting interferometers for quantum
communications at room temperature. (David came up with the math, I
came up with the devices. Details are at
<https://electrooptical.net/static/eoi/patents/US07889992__.pdf>)

We both left for greener pastures before I got those ones working. The
normal ACTJ detectors worked great.

Grin, I remember playing with ping pong with two experts.
(both physics professors, well now at least, one was a grad student
at the time.) We were playing doubles and I'm trying to return serve
from a master.. Nada...
"Hold your paddle like this", my expert partner says...
Face essentially parallel to the table... ~90 degrees from my
typical orientation. Serve comes in and bang, I get (for me)
a perfect return. Master across the table changed the serve
next time and the ball again went off in some random direction.
But I got one back!

Lim was showing off, so applied full spin. The ball hit my paddle flat
and headed off at 90 degrees, into a wall or the ceiling. Better than
hitting me, which bruised.

But the wasn't a very good engineer.

The Google team made some milestone that Scott Aaronson blogged about.

Well, you're pushing me on the math that I don't understand, which is of
course perfectly fair. ;)

I don't think it would, FWIW. Quantum communications allows exchanging
data that cannot be intercepted without disrupting the communication
channel, which ISTM is a helpful adjunct to crypto rather than an
antagonist.

I resisted working on quantum computers for several years because
undermining strong crypto would be A Bad Thing, but it turns out that
there are a lot of quantum-resistant crypto algorithms available.

Whether the 'perfect forward secrecy' property of previously-existing
algos will survive quantum attack, I don't know.

Yes. There are plenty of algorithms that run fine on conventional
computing and don't have any fast quantum algorithms for breaking them,
even in theory.

But there is also the practice - a standard, well-known RSA algorithm is
completely unbreakable (with any current algorithms) if the bit size is
big enough. A 2048-bit code is going to be unbreakable with any
conventional computer in practice (765 bits is the current record, I
believe). Breaking 2048-bit code with a quantum computer would take a
20-million q-bit computer, running continuously for 8 hours (in theory).
Current models can run about a dozen q-bits for a few milliseconds.

And no matter how big and powerful conventional or quantum computers
get, any calculations always have a minimum energy required. Moving to
4096-bit RSA is peanuts - but cracking it would probably take all the
energy from the sun's lifetime, no matter what type of computer is used.

Smarter algorithms for factoring big numbers are a risk for current
popular encryption algorithms, and could change things dramatically.
Quantum computers are not a risk.

Oh these were two good physicist's. Hung was a new hire,
and went on to be chair. (he was rumored to have had some
Chinese PP scholarship.) And on my side, (or I should say
crippled by me.) was J. Kono, now at Rice. Shaliesh and I
were about evenly matched... (I did grow up with a PP table in
the basement.)
Anyway we all had fun and I think the experts were trying their hardest
to win. Which is exactly what you want. So try doubles next time. :^)

The entangled 2 photon system is the cleanest I know of.
