Dunno, I would remove the batteries before storing them though.

I saw that or a similar article on the same subject and it seems to me they author really has no idea. At one point describing how a qubit can have multiple states then describing how they use a wire to determine the "spin" of the qubit setting either 1 or 0. I want to know how they can get a qubit to "spin" in both directions

The paper[^] doesn't make any claims about information storage. It sounds like you are getting speculation from a journalist. Don't believe everything you read online, journalists want more views sometimes at the expense of accuracy.
Let's extract the claim (last paragraph on page 2):Here we demonstrate ESR of single spins in a silicon metal-oxide-semiconductor (SiMOS) quantum dot (QD) device by using a compact dielectric resonator (DR) placed above the chip (Fig. 1B). The DR is constructed from potassium tantalate (KTaO3 or KTO), a quantum paraelectric material that exhibits an exceptionally high dielectric constant at cryogenic temperatures and hence compact microwave mode volumes. ESR control is confirmed to be resonator-driven by observing an enhancement in the mixing of the quantum dot spin states within the dielectric resonator bandwidth. This represents the first step towards the vision of large-scale qubit control using global magnetic fields generated off-chip.
Then look at the methodology/results, I am not going to paste it here because it's too long, but all you need to do is read the section labled 'Nanoelectronic Device and Spin Readout' on page 4. Note that in the final paragraph the authors state that they have only achieved "81% fidelity". Which is an middle/high error rate.
That's really all you need to look at. There is no claim about information storage.
Best Wishes,

Thanks. It sounds like it isn't just the journalist, though, because if you watch the “Missing Puzzle Piece”: Critical Advance in Quantum Computer Design video on that page, Andrew Dzurak makes it sound as if this will be the breakthrough that leads to heaven. But as you said, the error rate is still significant. Also, all this is doing is making a resonant field of quantum cubits, as far as I can see it. (If such terminology is valid for quantum particles.) That is effectively one qubit? (+/- 19%  )
Maybe he has had to write too many grant requests throughout the years, and is caught up in the heat of salesmanship?

Yeah,
It's speculation. I'm not an expert in quantum computing but from what I can understand the technique they are using looks very very promising. I do understand the most of the physics and the core idea that makes all it it work is explained in the section labled 'Nanoelectronic Device and Spin Readout'. It's actually pretty simple, once they reach a triplet state[^] the Pauli exclusion principle[^] prevents the electron from tunneling and it maintains it's state. This is the core idea behind their technique.
One of the biggest hurdles for me when I read these papers is that every science field has it's own nomenclature. For some reason the paper refers to the Pauli exclusion principle as 'Pauli spin blockade' abbreviated as PSB. It looks like this term is exclusive to the quantum computing field.

I bet spy agencies would pay a lot of money for something that could decrypt captured info 81% of the time.

It is the same technique as putting all the toppings on the pizza before putting into oven,
But, this technique facilitates the removal of half-alive cats, an optimization that saves toppings like anchovies.

I'm a little puzzled now ... Do you ever use half-dead cats for pizza topping?
|
|
|
|
|
It is the smoke from the half-dead cats that gives the pizza the special taste that people wait in line for eternity ... for.

Anyone here into Python and has some spare time? We have a project we need help with.
Email me at chris@codeproject.com if you're interested.

Hmm. It's not a programming question, but a job question. I think there was a "job" forum at one time, but there isn't anything like that now that I can find. Based on that, I think his post is okay.
Of course there's always the "his playground, he can break the rules any time he wants" principle, but...

Is it just me or has dialing in to speak to a Real Human become an exercise in being on hold for literally hours.
Every company has a notice along the lines of "Due to the COVID pandemic we're experiencing higher volumes blah blah blah".
It's been 18 months. How this means that my insurance broker, or local bike store, or an airline is now overrun with calls because of COVID is beyond me. I get that many are working from home but is the lack of staff to take calls because everyone who should be manning the phones is taking their dog for a walk? Or have slept in, again? Or that beer o'clock has slipped from 5pm to 4 to 3 to 10AM?
I'm just wondering what your experiences are, and if anyone who deals with high-volume inbound call systems has any insight into what's going on. Bandwidth issues due to people working from home? Systems simply unable to cope with offsite call-handlers so they are on 25% staffing? Burn out? Home computers still trying to update to Windows 21H1?
cheers

eBay and Amazon must be doing something right. Their human service reps seem to answer calls within the (accurately estimated) 1-5 minute period. With everyone else, it seems like a crap shoot.
