back to article Japanese quantum boffins 'may have the key to TELEPORTATION'

Don't get too excited, the world's not about to get Star Trek-style transporters. However, if a quantum communications theory formulated by three Tohoku University boffins can stand the test of experiment, they could break the distance limitations that currently constrain quantum communications. At this point, the exercise gets …

I really want a hoverboard... some of the self tying shoes and the self drying coat would be good too.

They had better be quick inventing these things, they only have 1 year left.

WTF?

Squeezed Vacuum

How the hell do you squeeze a vacuum? I sometimes think these physicists are just making things up to get more grant money.

Re: How the hell do you squeeze a vacuum?

Strictly speaking, a squeezed vacuum isn't a vacuum - it has photons[1] in it. It's called a vacuum because it has a zero amplitude, but in fact its quantum uncertainty has carefully arranged correlations, for which some excitation above the true vacuum are required.

Or: a squeezed vacuum not a vacuum, we just call it that because the field amplitudes measure (in average) as zero. But a photon number measurement will be non-zero.

[1] Assuming we're talking about an electromagnetic (squeezed vacuum) state.

Just don't install the carpet cleaner strength/debugging unit with the teleportonic shower replacement. You might REALLY be "washed up" beyond recovery....

I recommend reading Moving Mars by Greg Bear. This introduced me to quantum stuff in a sci-fi setting. It has always interested me since.

Don't worry about it. God thinks that way, too. He hasn't a fucking clue what it all means at the nuts & bolts level because that's the way he designed it. We'd like to think that everything is understandable, but that doesn't mean that's the way things are. It's one of the many reasons I get smashed at the pub several times a week.

Yes the words are simple. It's just that when they coalesce into sentences the meaning breaks down.

Which seems to apply to a lot of quantum physics.

To quantum physicists/metadatabase physicians, are the stealthy opportunities quite clear in the mean research and the security implications in the need for care in the use of marked and potentially classified ultra secret and sensitive discoveries, even more so, given what can be wrought and delivered for good and for bad in technologies/modi operandi and vivendi not understood and/or misunderstood.

Re: I think I speak for most when I say...

According to Deusenberg's Uncertainty Principle, one can know either what a quantum mechanic does or how much it costs, but not both.

If, at the end of the day, you pay him, since you now know both of those, something else will immediately break down; if you've used a charge card, that will happen when the bank pays it, generally at the worst possible moment while you are driving. Parity is sometimes conserved by them paying the wrong amount.

Re: The main question is:

Answer: With extreme difficulty verging on the impossible if they want to retain and maintain status quo intelligence applications/established politically incorrect situations?

And one would fully expect that to be the case whenever au fait and working and majoring with IT in its C42 Quantum Communication Control Systems …. AI@ITsWork fields. [C42.... Cyber Commanding Creative Control with Computers and Communications/Communicating Computers]

The real main question for the likes of an NSA and GCHQ, and one which they currently would/will most probably foolishly choose to studiously ignore and plausible deny is a problem they be trying to address and work around for it would be able to easily terrorise them, is how to stop such communications from entering their systems and applications and leaking to external third parties/other most effective non-state actor bodies, basemetadata discovered and being utilised therein?

Step carefully from here on in, for one false move in the wrong direction delivers exactly everything that one be fearing in failed intelligence circles with right royal dodgy promotions and unable to counter.

OK, so what are they actually talking about?

It would have been nice if the article gave a bit of clarity as to what possible practical applications this could have... if it's just being done for pure knowledge sake that's fine with me but let's make that clear in the article too!

A few minor implications...

Not that I understand anything about the science. But I wonder how much power a personal transportation booth would draw. There'd probably be one sitting in the hall of each house. But I find a lot of my friends insisting that we ought to save energy - and they don't listen to me when I say that there's a lot of energy in the universe. So I made up a little illustrative story:

1900 - typical power to transport a person = 1Hp

1950 - typical power to transport a person = 20Hp

2000 - typical power to transport a person = 100Hp

2050 - typical power to transport a person = ?

If the above trend is followed, it will probably be around 1000Hp, say, 750Kw. Which means that we'll need bigger cables going into each house. I don't anticipate any problems generating the power, but it certainly won't be from windmills...

Re: A few minor implications...

@ dodgy geezer

well, it's 2014 now and there's already 1000hp cars; 500hp is no longer uncommon (no need to cite- ask any gearhead); methinks Moore's Law might soon apply, if not already.

And as for cable size to operate telephone teleportation, I believe the gist of the article was energy teleportation, so Tesla was 100 years ahead of his time. A lot closer to reality than Leonardo, so perhaps Moore's law applies to more than chips. Look at almost anything in science, maybe less so in manufacturing. My Dad was born just 6 years after the first US patent for radio (Tesla again) and 11 years after the invention. Now we have telescopes in space looking back 13+ billion years (light years). We just can't go there (yet). Need I say "aircraft"?

Re: A few minor implications...

You haven't got an "above" trend - or if you have, you haven't got enough data to see what the trend is. For example it would be reasonable to llok at it and say the increase in teh first half-century was a factor of 20, in teh next half century it was a factor of 5, so maybe the increase factor goes down by a factor of four each half century - so for 2050 a good prediction might be 125Hp, which is a long way from your 1000Hp. Of course there's no reason to believe that a regular factor beteen each half-century makes any more sense than a series that alternates divide by 4 and muliply by 2 (which delivers 10 for teh third gap, so fits your 1000Hp).

My point is that on this data you have no evidence to suggest any value at all for 2050 - claiming it imolies "probably around 1000Hp" is just nonsense.
