Hot Qubits: major quantum computing constraints overcome

Most quantum computers being developed around the world will only work at fractions of a degree above absolute zero. That requires multi-million-dollar refrigeration and as soon as you plug them into conventional electronic circuits they’ll instantly overheat. But now a team led by Andrew Dzurak at the University of New South Wales (UNSW) has shown they can operate silicon qubits at temperatures 15 times hotter than most qubits, creating a path from experimental models to affordable computers for real world business and government applications.

Australia is rocking the quantum scene

Congratulations!!! This breakthrough is a major step to A.I and our civilization.

Hot Qubits. They are like normal qubits, but sexier.

Great video. If true, this is a GAME CHANGER, putting disruptive quantum tech into single-digit years.

I can't wait to see what it does for Fusion energy, Blackhole energy, and and energy generators of the future.

I didnt know bono was that smart wow!!!

[Czeckie]

does this result work for other silicon based approaches UNSW people work on? Namely Andrea Morello and his team.

[Makish]

anyone watching Devs and freaking out over this? ^^

[redshow]

will we be able to use quantum calculations in 6-7 years?

[koralite]

this is big! equal to discovery of writing!

Thank you but Archer announced breakthrough for its room temperature quantum computer...

[darkashes]

Could you make the Logic board big enough that can handle 1, 000, 000, 000, 000 CONVENTIONAL CHIPS than add 9 more of the same Quantum computer than hook it up than try to make new CONVENTIONAL CHIPS that can handel 10, 000 times hotter temperature and switch to replace the other ones leave the Quantum chip in it than make 9 more than hook them up and than change the hole technology including computer and batteries like Quantum batteries and star trek WARP DRIVE.

Another fundamental problem facing quantum computers is in fact fare more lower velocity of light in case of super low temperatures:
Very interesting discovery! But is it lack of convincingly theoretical explanation there? What actually happen with the matter in such super low temperatures? First of all several words about achievement of such temperatures: Micro degree (K) can to be achieved not only with the laser beam which is relatively new technology, but through magnetization and self demagnetization by which is swallowing heat even about nuclei’s magnetic moment demagnetization. Now about the explanation of this matter state which of course has nothing to do with the condensation. The truly answer is in superconductivity USM www.kanevuniverse.com which summarizing can looks like this: Because the field including nuclear attraction of electrons has inertial character (see part I USM) and because this field actually is creates by inter movement between the atoms (nuclei), follows that in such super low temperatures comes borderline case when this field becomes so weakly that it is impossible to withstand more and (firstly valence) electrons becomes “free” (insensitive – don’t exist about the host nucleus and other nuclei). That is why appears the superconductivity, super liquidity, but not because of some unclear essentially condensation. So why the light beam passes so slowly through such “ordered” medium? The answer again it isn’t condensation, but in this case see the next:
Very interesting question: “whether the speed of light is absolutely…” Of course not, but this is related only to the constant of light spread like a real number, not as a limited which we can’t reach! What I mean? Firstly see pages: 94 to 98 and pages: 198 to 202 USM www.kanevuniverse.com here was delivered these formulae: r=h/C.m where: r – is the resonance radius of the particle; h – is the constant of Plank; C – is the velocity of light; m – is the mass of particle; and this formula: C(i)=(C).m(p)/m(i) where: C(i) - is the constant of velocity of light (like a real number) about the different possible worlds (see shown pages); m(p)- is the mass of proton; m(i) - is the mass of current stable particle about current possible world; C – is velocity of light in our world where the velocity of light has this value (C). As it is seen on the shown above pages the resonance radius is connected with the mass of the particle which is stable particle in examined world and the real number of the velocity of spread of the field in this possible world. The important conclusion is not only possibility to be created “Oracul” (see the pages), but more importantly is the consequence that on the center of our galaxy (in fact any galaxy) where are situated and was born the proto particles the limited constant of spread of field (“light”) is different like a real number compare to this value in our space which is (C). That is one of the reasons that we can’t see the central zone of any galaxy! There springs up this question: Whether we can reach this zone in our galaxy and by this way we can travel whit the speed far bigger than the speed of light in our position on the galaxy which is (C)? The answer if no!
So in super low temperature borderline case when the electron “almost no more exist” for the surrounding matter (which is summing inertial mass) including nuclei, appears like a very light mass, which according to above equation has to be (very approximately) as much folds lower as it is the ratio between the masses of proton and electron divided by the achieved micro degree (K) which make up some number around 10 rising to a 10 power, which makes velocity of movement of this light beam approximate 1 cm/s. Why we have to divide by the achieved micro temperature? Well because that much folds is thickening the space of this matter. G.Kanev

So what about just putting these qubits into orbit, where the temp would be naturally closer to absolute zero, on a permanent basis, then plug an orbital supercomputer that takes data from it, then send the data down to Earth? Why waste so much energy and resources artificially when you can make it run in far better natural conditions?
