The breakthrough — achieving this "below threshold" milestone — means that errors in a quantum computer will reduce exponentially as you add more physical qubits. It charts a path for scaling up quantum machines in the future.
The technology relies on logical qubits. This is a qubit encoded using a collection of physical qubits in a lattice formation. All the physical qubits in a single logical qubit share the same data, meaning if any qubits fail, calculations continue because the information can still be found within the logical qubit.

Noah: (Looks up) Is someone calling me? (Shrugs and goes back to his work)
God: (Ding) NOAH!!
Noah: Who is that?
God: It's the Lord, Noah.
Noah: Right ... Where are ya? What do ya want? I've been good.
God: I want you to build an ark.
Noah: Right ... What's an ark?
God: Get some wood and build it 300 cubits by 80 cubits by 40 cubits.
Noah: Right ... What's a cubit?
God: Well never mind. Don't worry about that right now. After you build the ark, I want you to go out into the world and collect all the animals of the world, two by two, male and female, and put them into the ark.
Noah: Right ... Who is this really?

Its a maybe. Depends on how you look at it.
By contrast, Alan Norton, of NY’s IBM Research, was putting together a graphics presentation for a conference and this was the project video I made for him to show. In 1989, he was able to create a physically based world in graphics with laws of physics defining what would happen when you let it run, then kept adjusting things until his world did what he wanted it to. To do this, he was connecting together all of our computers around the world at the times when people were sleeping and there was less strain on the systems. The contrast between what was possible then and now is simply staggering.
The demo vase and teapot were grandmother’s and my bestie’s daughter was the one catching the teapot under the table each time Alan had a take. We had to spray non-glare onto Alan’s glasses to get thru this. He was truly one of the wonderful people at Research.

I don’t know how many qubits per second I’m processing, but I’m way behind
African or European?
As for Q computing... It will eventually make an AI that will be smart enough that we won’t be able to catch it lying to us...
My old deci-deci-log-trig slide rule might have done it just as quickly...
Our computers fill the hallowed halls.
A qubit is a quantum mechanics based superposition thing that is both 1 and 0 at the same time.
This is a little hard to grasp let alone explain. I’ll try here:
A bit (what normal computers work with including what you’re using to read this) is a 1 or a 0.
A qubit is both at the same time.
Example: factor (find the divisors) of 15. With normal bits you try 1, 2, 3 <- win! after three steps.
With qubits you try 1, 2, 3, 4, 5 etc all at the same time. Instant win in one step.
(I am massively oversimplifying but think it makes the point.)
An ark measure used by Noah. Yeah, I listen to Bill Cosby, too.
My parents had that album.
I listened to it a lot as a kid.
I am not certain that I would be “qualified “ but I grew up learning Basic on green-screen 7 1/2 floppy drives and later C+ on a 486 DX2. Quantum computing makes Deep Blue look like an oversized punch card computer ... sound about right?
Don't laugh, that's the key to making many "brute force" approaches feasible, and that's why our current used encryption algorithms are at risk.
With that said, I don't think quantum computing really works, otherwise someone would have made off with a good chunk of the cryptocurrencies by now.
thank you; how did his prediction for 20 years later wok out?
The Three Body Problem?...................
I'm secure in knowing that after Biden's swan song nuclear holocaust, my trusty K&E slide rule will still work fine.
The mouth on that guy!
Regarding three gravitational interactions ?
Who in hell figures this out - the same geniuses who tell me that my LED light bulbs that burned out in 8 months are going to last 13 years?
Yes. It has been said to be impossible to solve...................
