Knots, World-Lines, and Quantum Computation | Steve Simon | TEDxOxford

In this talk Professor Simon describes the connection between knots of string and certain elementary particles, and how this connection could enable quantum computers - a revolutionary type of computing
device. Beginning with the notion of Einsteinian "world-lines" - the paths traced by particles as they move through space-time - he explains that experiments on elementary particles give information about the knots formed by the particles' paths. This information is not easily calculated on any conventional computing device, thus showing that the quantum particles themselves have some sort of "higher" computational ability. The realization that quantum particles have computational ability opens the door for using these particles, and these knots, for doing other computations that would be impossible on any computer currently in existence.
Professor Steve Simon is a world renowned theoretical physicist who has worked at Harvard, MIT, and Oxford. He blends an exceptional knowledge for the field with an infectious enthusiasm that will excite, entertain, and educate.

[@ShahryarKhan-KHANSOLO-]

Haven't listened to such a clear presentation in ages. Everything clicked so nicely. Hats off to Dr. Steve Simon! I now want to look more deeply into knot theory and its relation to quantum physics.

[@alsilver123]

@7:24 - 7:35 he reference steins gate

[@ancbi]

That's the level of details that would be really allow interested people to look deeper into it. Great talk, thanks.

[@Aman-tf8bt]

wow he explains very lucidly and simply ,amazing

[@irslanullahashraf5158]

what a clear clean and super explanation ... it take hours to plan the presentation for such complex concept... but he make it really simple...Prof. Steve Simon is Quantum Computer of clean information transfer to the students.. when he teaches, It feels like we don't want to breathe as it might distract our attention... he is God gift to the Students... I am fan of his teaching ... I wish I would meet him someday...

[@subramanyam2699]

Amazed to see that knot theory has such good application!!

he's just tieing you into knots.

[@GooseHen25]

Durzo -ropey joke that.

[@naimulhaq9626]

Bell Laboratories produced transistors with three terminals giving an input/output amplifier with semiconductors. Quantum computers give superposition of many intermediate states between 0 and 1 called Qubits, which will require many terminals (like knots) giving the intermediate states, like the topological quantum computers.

Oxford seems to be in love with academic twaddle (I've seen it in their choice of published philosophy, too). Ted talks have become inundated with twaddle in general. The real question is, would I continue to fund this line of thinking if my goal was to understand reality in the hopes of securing higher consciousness in a harsh and deadly universe... The answer is 'yes' (if I could afford it, for it would be quite low on my priority list), if only for diversity of mind (the key word, with respect to survival, is 'diversity', which is still a critical factor) - meaning offering another potentially-useful perspective with which to peer into the unknown with, where the more perspectives you have in your perspective toolbox, the higher the more likely it is that you will 'unravel' (to pun this video) what it is out there in the unknown (and usually right in front of your nose the whole time) as we attempt to discover threats (or benefits) to life in general (and higher consciousness in particular, since it gets priority).

[@ajp8025]

too (though it is relative ) many (within the context of fractal language forms) parentheses (mate)

[@alan2here]

Perhaps if your ok with lose ends then you can do the huge knot in manageable chunks.

[@RobertsMrtn]

At first I thought that he was alluding to a theory that particles are actually knots in space/time but this did not happen. Also, it seems to me that instead of introducing complicated algebra, all one really needs to do is to apply twist and slide transformations to deduce whether two knots are topologically equivalent.

[@m0zzar353]

yes but twisting and sliding knotts with massive crossing numbers would be impossible

[@navalrsabe7015]

[@hsuklivex4845]

Amazing

[@debyton]

It looks like who ever made the slides got the first EQ substitution wrong the pic-symbols in each bracket are reversed with wrong coefficients.

[@ninjaman3206]

debyton If you look closely, the 2 crossings in the "knot" we are presented with are different. The crossing shapes are different, thus the coefficients are switched.

[@waynebiro5978]

The thing is there were different ways the two-cross knot could have been solved - he simply ignored, on a whim, the other possibilities.

[@GuillermoRobles]

So annions are like ALEXANDER THE GREAT when it comes to knots?

[@JibinPhiliposeDGameR]

isn't quanrum computer already built and situated in NASA which Google too helped to make and even an university has made and experimenting further for more functionalities of quantum computer application's. Then why in the end did he say that quantum computer has not been built yet.?

[@Runeansfelt]

+Gamer D Yup DWave 2 X ;)

[@everetts-cat]

+Gamer D Because D-Wave hasn't yet convincingly shown that its computer is indeed quantum.

[@danielneuwirth1843]

+Gamer D The quantum computer D-Wave from google does not out preform a normal computer for any given benchmark. Either quantum computer do not work as anticipated or google makes a scam. The fastest algorithm for knots takes ex-time. But there exist no proof that it is in NP or BPP. (how difficult a problem is in respect to other problems). To claim that you can solve all problems if you solve only one non related problem, shows the poor understanding of math.

[@JibinPhiliposeDGameR]

Daniel Neuwirth I don't think that benchmarks tools exist yet for quantum architectural processors so there is no reason to compare with that yet and secondly about algorithms I think with time The best NASA and Google enginerrs/scientists will come up with good complex algorithms to make the best use of the quantum processor to solve complex problems which our normal processors can't.

[@Epoch11]

+David Möckli Exactly right and they need to figure out how to program it, keep it near absolute zero as well as overcoming other technical challenges. They are also trying to make quantum computer out of silicon with a single embedded atom (I believe they are using Sodium, but I could be wrong) that would not have to be cooled to near absolute zero. We have a long way to go for viable and reliable quantum computation device.

[@davidwilkie9551]

Making String Theory into something it is knot? Probably not.

[@noninvasive_rectal_probe8990]

Cinema, LOL!!!

[@elijaprice]

Really boring presentation...............not.

[@obergssin]

Ok let's see the quantum computer solve that factoring problem at the end then ..... Bogus ...!

[@NahidMuzammil]

12:15 3 crossings, 9** diagrams. He said 8. Ha, I'm smarter.

[@l4r5m4r5]

It is exponentially hard to calculate, so for 3 crossings we have 2^3=2*2*2=8 diagrams. Similarly for 4 crossings, we have 2^4=16 diagrams; the number of diagrams doubles for each crossing we have.
