Researchers Unveil First Ever Blueprint To Construct a Large Scale Quantum Computer (phys.org)
haruchai quotes a report from Phys.Org: An international team, led by a scientist from the University of Sussex, have today unveiled the first practical blueprint for how to build a quantum computer, the most powerful computer on Earth. The work features a new invention permitting actual quantum bits to be transmitted between individual quantum computing modules in order to obtain a fully modular large-scale machine capable of reaching nearly arbitrary large computational processing powers. Prof Hensinger said: "The availability of a universal quantum computer may have a fundamental impact on society as a whole. Without doubt it is still challenging to build a large-scale machine, but now is the time to translate academic excellence into actual application building on the UK's strengths in this ground-breaking technology. I am very excited to work with industry and government to make this happen." The computer's possibilities for solving, explaining or developing could be endless. However, its size will be anything but small. The machine is expected to fill a large building, consisting of sophisticated vacuum apparatus featuring integrated quantum computing silicon microchips that hold individual charged atoms (ions) using electric fields. The plans for creating a universal quantum computer has been published in the journal Science Advances.
What does this have to do with quantum computing. Oh wait... maybe you're onto something. Trump is a Quantum politician... he's able to occupy a superposition of realities at the same time. It's not that the crowds at the inauguration were larger for Obama, it's that unlike Trump, normal people living in a collapsed state cannot see all the people from the alternative universe.
Someone had to do it.
Quantum computers are built for specific workloads. Citing this as potentially the worlds fastest computer is misleading. It more than likely will not be a general purpose computer.
So he's SchrÃedinger's President? Can we prove this by collapsing the White House?
It can't run crysis...
...Both welcome and condemn our new quantum overlords.
I want to be a billionaire in 20 years!
I am very excited to work with industry and government to make this happen Alternative Translation: We'll all pay $50 billion dollars for it, it'll go 16 years over the scheduled timeline, and barely work, being less powerful than a Fitbit. Kinda like the border wall Clinton and Schumer voted for a decade ago, which will start being built maybe next year. Government - the original Kickstarter scam.
It will be used to unlock a few phones which will hold no useful information.
Prof Winfried Hensinger (2), head of Ion Quantum Technology Group (3) at the University of Sussex, who has been leading this research, said: "For many years, people said that it was completely impossible to construct an actual quantum computer. With our work we have not only shown that it can be done but now we are delivering a nuts and bolts construction plan to build an actual large-scale machine."
Nah, we think you built another analogue computer, and branded it 'Quantum' while it doesn't actually use entanglement or quantum effects.
*********
So not 'entangled qbits' I see, more like electrically connected qbits? Or are you claiming entanglement?
Can you make an experiment 'proving' entanglement that doesn't PRE-FILTER the experiment results? No 'co-incidence' circuit, no plain ass filtering, like in the Delft experiment? Because every single entanglement experiment pre-filters the result before shoving it into the Bells test. That pre-filtering adds the very effect they're trying to test for!
If you select photons emitted at the same time, then they will likely be created in the same event, and have related properties assigned by that event. So the fact the properties are the same, is a consequence of selecting that subset of photons with your filter. In Quantum Eraser experiments, this filtering is done with the 'coincidence circuit'. In Delft's experiment they compared the two result photons and discarded experiments where the photons weren't identical. About as blatant a science fraud as it gets.
And in your quantum computer, if you think you have linked qbits, do you also have a signal indicating 'successful linkage between these two qbits'? i.e. the filter signal? A signal sent by the usual means electrical, optic or otherwise?
Or is this another analogue computer dressed up in 'Quantum' brand naming?
I'm guessing the latter.
How does one encode information in an ion? From the first video in the link it would appear ions selectively traverse resonance chambers controlled by microwave electromagnetic fields to reach a given detector. How does one translate the constraints of the problem being solved into microwave em fields? Without answers to these and many more questions this is merely a fluff piece hardly worthy of being news for geeks, stuff that matters.
No need to build a quantum computer for it.
In the current political climate, a computer that can simultaneously deal with facts and unfacts may have useful applications. In the past, we only needed to keep track of real data. Going forward, it seems we need to simultaneously handle both actual data and what the user wants to be the actual data. Being able to draw conclusions from the superposition of both versions of reality needs to be extended from social media into practical applications.
This comic is a more in-depth yet accessible explanation of quantum computers than anything I'd ever read on Slashdot.

... how fast will it play ARMA3?

The most encouraging thing in this news is the way it was done. A collaboration that was then published to the world. Now will come the hard work: not just building this massive machine but teaching a generation of programmers an entirely new way of programming. My understanding after following this subject for years is that it will require a completely new way of writing code. That may well be as big a challenge as the construction itself.
Let's cock fight, whose cock is smaller. Tim Cock will mary the winner.
However, its size will be anything but small. The machine is expected to fill a large building,
That's OK. To (mis)quote Thomas Watson, I doubt the world will need more than 5 quantum computers.
politicians are like babies' nappies: they should both be changed regularly and for the same reasons
"Researchers Unveil First Ever Blueprint To Construct a Large Scale Quantum Computer" - or not???
...should be enough for anyone, ever!!!!...

Multiverse fork here... one Earth survives, one does not.
If you take just one piece of information from this blog: Quantum computers would not solve hard search problems instantaneously by simply trying all the possible solutions at once.
In keeping with my biologist-level of understanding of quantum theory, I think I can't be sure if I do or if I don't until I actually taste it.
I'm sure that D-Wave is quaking in their boots. You know, the makers of an actual quantum computer, versus the planners of a theoretical quantum computer. Which isn't much changed by the news that the OP researches have made a "practical blueprint".
Or do you think that quantum annealing doesn't count?
Don't know why the parent is modded down when it is an informative rebuttal to the GP. The GP is a troll that spams the same horrible misinterpretation of QM to every vaguely related Slashdot article. It gets pointed out as wrong almost everytime, but keeps getting posted in the hopes more knowledgeable people get too lazy to tear it apart, or a least too slow to tear it apart before the original garbage gets modded up.
Can we call it ENIAC too? I mean, ENIAC 2?
And in 20-25 years, the desktop will be a PQC - Personal Quantum Computer!
