They still do experiments? I thought they just sat in their offices and spun string theories.

a length of about 10-35 metres . . . The Planck length, far smaller than any elementary particle or distance that we could measure, is the ultimate quantum uncertainty in location

Thus making it extremely problematic to "walk the Planck" .....

Of Interest.

A little beyond my expertise, but I’ll just string along.

Everything is binary.

I will leave it at that.

This was very interesting but what will be more so is if they do find something.

Or Donald Rumsfeld would put it: Reports that say that something hasn't happened are always interesting to me, because as we know, there are known knowns; there are things we know we know. We also know there are known unknowns; that is to say we know there are some things we do not know. But there are also unknown unknowns -- the ones we don't know we don't know.

Got that? Good.

Similarly visionary experiments could use entanglement to examine the history of the Universe. In theory, as the cosmos grew from its tiny beginnings, the corresponding changes in spacetime curvature should have altered entanglement in ways that can be traced back to presently unknown details of cosmic development. Entanglement studies could even bear on an old cosmological question: are the physical laws that we have derived on Earth valid for the whole Universe? Since the time of Copernicus, scientists and philosophers have considered this question from different perspectives, but have had little direct evidence to draw on. If entanglement proves to be truly infinite in scope, it could be the ultimate tool to glean answers from distant cosmic locations.

For some reason, when reading this part it reminds me of the details of the Infinite Improbability Drive in the HHGTTG.

“And there’s one area where the use of qubits is anticipated with particular eagerness: data security. In any communications system, sensitive information such as financial data can be encoded and sent to a recipient who has the key to the code. The trouble is, it’s always possible for a third party to sneak into the network and secretly learn the key. It was this kind of breach, for example, that recently leaked the credit card numbers of millions of customers of US retail chains such as Target and Home Depot. Qubits should prevent that.”

This is a double-edged sword, actually. Qubit based encryption might be much stronger, however, the appearance of usable quantum computers would instantly make insecure all non-qubit based encryption that was previously used. So all the historical data that is sitting around, encrypted under the old standards would be like open books to anyone with a quantum computer, since they could brute force the encryption open in minutes, perhaps seconds.

too many science writers know nothing of how to cut down some of the forest so the tree can be seen

sometimes too much explanation is not better “science” it’s just failure to get straight to the point

Entanglement has been tested up to a distance of 143 km, by Anton Zeilinger at the University of Vienna.
In 2012, Zeilinger’s former student Jian-Wei Pan, who heads the USTC quantum satellite effort, achieved entanglement over distances nearly as large.
And then, in an important ‘proof of principle’ demonstration in 2013, he managed to transmit photon qubits 800 km from a ground station to an orbiting German satellite and back.
Results like these start to make quantum research in space look very doable.


Yeah, sure.

Then, the next thing you know....

We'll have THESE guys taking over our planet!!

What we don’t yet know is what happens to quantum phenomena over long distances. In short, we haven’t tried to do quantum experiments where relativity gets in the way. Yet.

What about the quantum phenomenon of what Einstein mockingly called "spooky action at a distance?" aka, EPR Paradox, Belles Theorem, non-locality, where a measurement on one particle of an entangled pair affects the other instaneously over artibitrarily long distances of space, in theory, across billions of light years.

This references two of the most important events in quantum physics. And now, you too, can get your copies of these events.
