This appears to be a fairly significant breakthrough for silicon based logic gate quantum computing.

From the article.

>A team of researchers with the University of New South Wales (UNSW) in Sydney has achieved a breakthrough in spin qubit coherence times(opens in new tab). The research took advantage of the team’s previous work on so-called “dressed” qubits - qubits constantly under the effect of an electromagnetic field shielding them from interference. In addition, the researchers leveraged a newly-designed protocol, SMART,(opens in new tab) which leverages the increased coherence times to allow individual qubits to be safely coaxed to perform the required computations.

Important takeaway.

>The UNSW researchers’ efforts have shown that groups of qubits can be controlled through a single, microwave-based magnetic source. In contrast, applying an electronically-controlled magnetic field can better control individual qubits. According to the researchers, the SMART protocol leverages a potential path for full-scale quantum computers.

>“We have shown a simple and elegant way to control all qubits at once that also comes with a better performance,” says Dr. Henry Yang(opens in new tab), one of the senior researchers on the team.

My take is this. Humans don't give up on anything. I see so much pessimism here that this or that is not going to be possible for decades, maybe centuries, maybe ever. The reality doesn't work like that. Humans will, in the words of the late great Norman Schwarzkopf, in answer to the question from a reporter during Operation Desert Storm about how he was going to proceed when he asked Schwarzkopf; "Are you going to make a main thrust through their lines?" And Schwarzkopf answered him, and I may be misremembering the quote precisely, but he said something like this.

"We are going to going to go through, over, under, around, any which way we can to achieve our military objective."

Well, that is how humans are in our efforts to develop our technology, especially our computing and AI technology as fast as we possibly can. And make no mistake. This is not an "AI winter" issue any longer. Now it is a matter of national security and probably economic supremacy for the USA, China (PRC) and yes, Russia.

I see that the most profound and impactful developments in quantum computing seem to mostly come from UNSW. And I am truly grateful for their efforts. I wonder why the US quantum computing efforts aren't as fruitful.

But in any case, it is not just computing/AI alone. It is the exploitation of said computing/AI to make level 5 autonomy vehicles. It is the exploitation of said computing/AI that will make bipedal humanoid robots that will be difficult to tell from living humans, until you are up "pretty close", within the next ten years. It is the exploitation of said computing that could produce an AI that might be able to solve the politico-economic and yes technological puzzles and problems that bedevil mankind to this day. In less than ten years.

I have great faith in our scientists, engineers and technologists that they can solve all of our problems, in maybe the next 20 years, but mostly within the next ten years. I put it like this in a comment from 2017. A technological lifetime ago.

I would have downvoted that, but I never downvote anyone.

So what does this mean? What's so important about it? What does this help us in?

Schwartzkopf "solutions" aren't a great analogy for quantum theory progression

Well, we are attempting to come at quantum computing from several different angles. The one I have a special delight in, is that of photonic quantum computing. The idea of using photons as qubits and having the capability of operating a quantum computer at room temperature really captures my imagination. I don't even know if photonic quantum computing exists outside of the theoretical, but most of our work in apprehending and exploiting these laws of physics to develop ever more powerful computing, be it binary or quantum and especially the development of computing derived AI whether binary or derived from quantum computing is attacking the problems from many different directions, "thinking outside of the box".

I don't know if quantum annealing computing is being currently used to help develop AI. Narrow optimization problems could a part of what successful AI/ML requires. I do know that a great many high level customers, purchased the D-Wave quantum annealing computer. People like Google, and JPL and Oak Ridge and Goldman-Sachs to name but a few. Oh and NASA Ames.

I think the Schwarzkopf quote is actually a very good metaphor for all of our efforts to develop our technologies. We are coming at these things from every angle possible.

ok, but realise using quotes from mass murderers is likely to give a negative slant to the tech

In the USA we don't see him as a mass murderer. He was an unmitigated hero to me. He got the war over fast. He got me home fast. The ground war lasted 100 hours. I was a regular army rad tech at 85th Evacuation Hospital (My unit from Ft Lee VA) located right up against King Abdul Aziz Airbase in Dhahran. I mean the wire fence of the airbase was just behind our tents. When the air war began it was deafening as groups of US, British and French attack aircraft took off seven at at time.

We were the only non-fixed advanced hospital that received casualties from the Scud missile strike attack on the US National Guard barracks about 7 miles away from where our mililtary hospital was sited. The impact of that Scud, about 8 pm our time was LOUD--it shook the ground were we were, 7 miles away. 27 Guardsmen and women were killed. It was about 72 hours of genuine mass cal war casualties for us. I saw bad things, but that's how it is when you are in war.

We also received more than 100 injured from the regular Iraqi army and the Republican Guard. One RG casualty had been severely injured in his upper thigh about 2 weeks before he got to us. His deep wound was swarming with maggots, because his people neglected him. The stench of decay was horrific. He was overjoyed to see us. And he thanked us profusely over and over again. All RG patients were handcuffed to their beds and watched over by MPs.

I was at Operation Desert Shield/Storm from 20 Oct 90 to 10 Aug 91. I'm 62 now.

Are you in the UK? You use the British spelling of "realize". I know that a lot of Brits don't like Trump and the Republican party. 50% of the US population loves Trump. 50% of the US population hates Trump. The US is now in what I would characterize as a "cold" civil war. It could turn "hot" easy.

I, however, loved your Queen. She was a hero too. She was what we in the USA call an honorary member of "The Greatest Generation".

Thanks for the story. Glad you survived and are surviving dude. Please point that intelligence towards peace and improving these shocking statistics.

I'm sorry whoever downvoted me with no comment disagrees, but it is what it is.
