Controlling four million qubits at Zero Kelvin

[NavyDiver]

Many of the quantum computing technologies operate at around 0.1 Kelvin, or just above absolute zero — which is -273.15 degrees Celsius.

Quantum chips have to operate within vast dilution fridges in which isotopes of liquid helium are pumped through a system of tubes that look a bit like a chandelier or an upside-down bird's nest. "And that's the easy bit."

The hard -impossible bit was millions of Wires to millions of Quibits has been solved by a Aussie team[thumbsupbig]


Controlling four million qubits at onceTo get around these problems, Dr Pla came up with the idea to get rid of the wires altogether and replace them with a magnetic field from above the chip that can manipulate all the qubits simultaneously.

Enter something called a "dielectric resonator (https://www.abc.net.au/news/science/2021-08-14/australian-research-puts-larger-quantum-computers-within-reach/100371544)".

And all we concentrate on in Oz is how much we can dig out of the ground and flog overseas. Crap foresight and leadership, crap nervous voters.

I feel some of our bio tech and new tech is world leading plus. I fully agree that many of our so called leaders just want to dig coal out and flog it off[bighmmm] Many of our brightest Computer types from oz are in lead ship just not here in Australia sadly.

And iron ore.......... blah, blah.

Point is that you can't keep doing it forever and by giving those industries tax breaks just sends us backwards in the world faster.

Problem is that controlling four million qbits does not pay royalties (and company and personal tax) to prop up this year's budget, nor any possibility of doing so before the next election. Nor does it prop up the exchange rate to give the voters cheap imported goods and cheap holidays in Bali.

You may not like it, but Australia's standard of living has been kept among the highest in the world by mining since the 1850s, and to a lesser extent by sheep since the 1820s.

IP to license or ability to make things others cannot in Computing is a massive economic enabler "A $150 million chip-making tool from a Dutch company has become a lever in the U.S.-Chinese struggle."

ASML Holding N.V. 14 billion turnover an rising suggest computers can turn a profit IF its is do the right way.

Quantum computing is about to make our current ones a little like the computing power on Apollo 11 Apollo Guidance had just 32,768 bits of RAM. A tiny running watch on my wrist is 4 gig of memory and your phone is much smarter the that yet every thing we have as obsolete as the the 1969 tech[biggrin]
My first mates 8 bit comodore 64 to the 64 bit computers now is hardly close to the changes we should see in several years if every thing works[biggrin] "PsiQuantum, co-founded by two Australians, raised close to US$450 million in funding to build what it claims will be the world's first commercially viable quantum computer."The UNSW team's solution to global control "is the beginning of a story rather than the end of one," "

Billions being invested in this is not charity. UNSW is in the running in a very interesting way.

All correct - but none of this is as certain to prop up the government budgets or exchange rate this quarter or before the election as is existing mining operations. And all that matters to the elected representatives is whether they win the next election, to the business managing MBAs what is the bottom line this quarter, and to most voters that think about this sort of thing what is their cost of living now.

And none of this is helped by the denigration of science and technology by most media, especially relative to sports or even arts, that has been going on for decades.

Fully agree John. A Perth based company has made a blood test which could save thousands if not millions of lives yet seem to get almost overlooked rather than applauded. The discovering Scientist in my opinion should get a Nobel Prize and more. Noting she might be based OS and was born at that location. I'd make her Australian of the year and try and make sure the manufacturing side is local- It is highly likely to be licensed for other majors to produce if it is not snapped up entirely. That's not entirely of topic as it is amazing algorithms making the cancer detection for several cancers possible. [thumbsupbig]

All the cool computer gurus I know all work overseas making lots of money for other countries and not ours[bawl]

but can it play crisis? or cyberpunk?
