The Quantum computer never looks at the coin before the second flip and you never said whether you flipped it or not. The quantum coin is put through a quantum gate that says: "if the coin is tails, flip it, OTHERWISE the coin is heads, so do not flip it". The quantum coin goes through this gate and the coin is returned to you. Now.. or some time later... you decide to measure the coin and it is HEADS. You never told the quantum computer whether you flipped the coin or not, so there is no way for the quantum computer to "know" whether it was heads or tails prior to its last flip. AND you can observe the quantum computers code to see that it did not "LOOK" at the coin. It just turns out that the final observation of the coin will be HEADS so the logic gate prior to measure will just need to operate or not in order to ensure that the output is Heads. The quantum computer will have flipped it or not to make it heads even though we are all certain that it COULD NOT KNOW whether to do that at the time it went through the decision making quantum gate. The quantum coin changed from 50/50 heads/tails INTO 50% heads NOT flipped and 50% TAILS flipped. So the result will just appear to be 100% HEADS. It's like we rigged the machine to produce HEADS and when we look and see HEADS we realise that the gate must have operated in the manner required to counteract the flips we decided to do in private and without forethought or collusion. We are looking at the answer heads in the future to find that the undecided gate had actually preformed properly even though it could not possibly know exactly what to do at the time. It's magic time and space changing logic gates that works in retrospect in order to produce the reality that you now observe. Fix your reality on the idea that the computer WON and then you will find that the choices that lead to that win will have to be the ones that resulted in the computer winning. Therefore, the last flip must be correct or there is no logical path from the initial state of the coin to the final measured state of the quantum computer winning.

@@peawormsworth , your explanation is really not right. Anyone who is confused about this should read about the Bloch Sphere. The sequence of gates being used is the following: the computer does a Y/2 gate, then the gates they give you access to are X gates (these could be interchanged, they just need to be orthogonal). Normally an X gate would flip the qubit from 0 to 1 or vice versa. However, because it is aligned on the X axis by the original Y/2 gate, it does nothing to the state of the qubit. Then the computer uses a -Y/2 gate and returns the qubit to its original state

Imagine the coin was painted black both sides. At the end of these blind hidden flips, the top is washed off and the winner is always the quantum computer. That's the surprise. The computer is not "reading" the coin state and flipping it to heads. It sees the black coin as a q-bit being both heads and tails (50/50) and puts it through a flipping gate which flips it if it is tails and leaves it if it is heads. So it always wins with heads. Even though it never looked at the coin, it just put it through a gate which operates or not in order to produce the desired outcome. Since the coin state CAN NOT BE KNOWN prior to measure (according to quantum mechanics), the computer both flipped and did not flip the quantum coin in order to ensure that there is a 50% chance the coin was heads and didn't flip AND a 50% chance the coin was tails and did flip to heads. So although it cannot know the state of the coin prior to the last flip or even whether it flipped the coin on its last choice, it will find that the result is Heads. The computer will just find that it flipped the coin when it needed to and didn't when it was not, because that is the only output of the q-bit state that is allowed by the logic of the gate we put it through. So no matter what we do with the coin prior to the final flipping, the final flip will be whichever one was required to meet our observation that the computer won with Heads.

this doesn't explain much about how it works at all.

The answer to that is maybe.

Actually I did kind of get this. We know that modern computers work with bits representing 1s and 0s and combinations of them to represent data. Bits can only ever be a 1 or a 0, but never both at the same time, the same as when you flip a coin and see the result, you can't have heads and tails at the same time. With a quantum computer however, bits can be both 1 and 0 at the same time. If you understand Schrodinger's cat, it's basically the same principle, it's only when you look into the box will you see whether the cat is dead or not, but you can never know the answer until that, so you have to accept both possibilities at the same time. That's why quantum encryption is unhackable, because even if you manage to "see" the data in it's quantum form, it's kinda like you're trying to figure out whether the cat is dead or not. If you ever delve deep enough into chemistry and physics, you might have heard that, rather than orbit the nucleus like a planet in a predictable path, it's kind of impossible know where exactly an electron is, it's at every point around the nucleus at the same time whilst also not being there as well. *mind explodes*. The fact that we struggle with these mind boggling concepts and pinpoint things is precisely why the quantum computer is useful. It's bits behave the same way. That's why it's useful for chemistry, because it imitate the behaviour of atoms in the same black magic way, we can model reactions without having to worry about the infinite crazy possibilities the direction of a particle might fly off to, and then translate the important information to us in a digestible format. At least that's what I'm getting.

she left out the most important part, the explanation is smoke and mirrors: the results of the human players and the "computer" are "read into" the system and "processed" SIMULTANEOUSLY. The results of human and computer coin tosses are ENTANGLED probabilities. The probability of one coin toss IS the probability of ALL OTHER coin tosses. Quantum entanglement is the key: The change of spin of one quantum IS the exact proportionate change of spin of another entangled quantum. What you need is an array of quanta that is set up for EXACTLY this task and no other, which is no trivial task at all. This goes to show how immensely important "mystifying marketing" is for those guys and what immense budget is behind that lady speaking. I wouldn't be surprised if there were several people in the audience laughing on cue to make this presentation seem entertaining. This is not an educational presentation.

Damn i loved the way she taught us the concept of quantum computing very knowledgeable and fascinating. Thanks ma'am

One of the best explanation I have found so far.

Discovering a new possibility on something we weren't aware is always thrilling.

So where does Quantum leap come into it? Used to love that programme 🤔

5:21 I'm a little confused. I thought the qubit, while in superposition, is both a 0 and 1 but when examined, reveals a 0 or a 1. In other words, a photon in superposition has both spin up and spin down but when tested to find spin, it shows one or the other, 1 or 0. Is the computer manipulating the "photon's spin" if the outcome is not the desired one. How can it choose?

That make no sense. You are flipping a coin but the computer is flipping a sphere. You are not playing the same game.

My knowledge bank is increasing daily. Thanks so much Ted x for creating a platform like this.

So if I understand this correctly (which I very well may not), in a game of chance where the rules are determined by laws we understand and can observe, a machine with quantum properties can manipulate the variable outcome by deconstructing and then reconstructing the matter upon which the variable relies to produce a definitive result? Basically what I'm asking is in a game of quarter toss, does the quantum computer dismantle and then reassemble the quarter so that it's always facing up?

As in the above application of coin game when playing through the quantum computer, we first take the choice of head, so after all the process done by the quantum computer means after the last flip as quantum computer unmix the 0 and 1 and perfectly the recovering the heads. this is how it works. but when initially we don't know the coin (as in this case "heads") so that both gamer and quantum computer had equal amount of chance like 50% .

Wonderful!. Quantum physics is a panacea for all our security and trust issues of today's computing/internet/digital world!!

This is so interesting and she explains it so simple.

So, the whole "teleportation of information" thing is a misnomer which is highly confusing for people not familiar with quantum mechanics. When 2 elementary particles, A and B, are interacted together, you can measure their sum to be 0 charge or 0 spin, which means one has +1 charge and one has -1 charge, or +1 spin and -1 spin. You don't know which of the two has what, but they never un-entangle themselves. You can separate the particles by as much distance as you'd like, and separately observe them to be +1 and -1, but A cannot be locally affected by B faster than the speed of light. If you only observe A, then B will collapse into the opposite state for as long as you observe A. Once you stop observing A, both A and B become randomized again until you observe them, at which time they can again be +1 or -1, randomly. This is called a non-local effect, because A and B effect each other regardless of separation in spacetime. But anything that A does (say, an electron making a magnetic field) that can travel to B's location and then affect B does not happen faster than the speed of light. In essence, that means this is useless for teleportation of information. Hope I wasn't too confusing...

Exactly. I came to the comments to see if anyone questioned the "teleportation" mentioned in the video. You cannot make changes to entangled particles. When you observe one of two entangled particles to be say, 1, the other is now instantly set to 0. Before you observer your particle, it could either be 0 or 1. Let's say when you observe your particle, it turns out to be 1. That means that the other particle is definitely the opposite: 0. As a result, you cannot use entanglement for data transfer.

Clear explanation! Now I can see the IBM's quantum computer is different from current ones. What does computer use for doing calculation ? LSI?

Genuine Question ? So the state is on , off or inbetween for now, so within quantum computing when will it realise that there are states between off and inbetween and inbetween and on ? then how many states will it calculate in these states,? does this mean that it could be infernate as Quantum computing evolves ? please respond I need to know

Very nice indeed. The computer does not tell you what happens in between. But it makes sure to display the final result to be heads. I could design such a computer without the super conductors that ibm use :-)

And ?

For what I've understand the game just gives emphasis on the super-position. So in the first flip it doesn't let go any of the two outcomes, rather hold on to both of them via superposition. Since the computer kept that in super-postion the players choice will also be in superposition. And in the last move computer just boosts the head probability so the computer wins

Excellent Insight from Classical Practicality to Quantum Reality ; Thanks in advance for updating the present status of your Q Internet research endeavor Thanks TED

can we check (the same game on Q-computer) what happens when the results are not pre-defined? Meaning it is not known ahead of time that Head will win or Tail?

What quantum computing actually is. Binary: 0 or 1. Never one and the other or both Trinary: 0,1,2. Never one or the other or both. Quantum computing: (0,0) (0,1) (1,0) (1,1). It basically makes things more probable or makes simple code more complex and bigger.

Im in IT and I love standard computers because you tell them what to do, always! Once you start letting computers think for themselves? George Orwells predictions come to mind.

@EngineerWhen

A particle cannot go faster than the speed of light, that's true, because photons have no mass, so they're "lighter" (pun definitely intended) and can travel faster. Here though no particle is in motion: there are some particles which are just connected, in some way, through the so called entanglement. If you change the state of one particle, the state of the other changes too, even though they're far apart, and that's how you transfer information. Think of it as a kind of "shared file" that everyone who has access can modify: as soon as someone makes a change somewhere, everyone who has access can see the part that's been modified.

Madam, I am from India.. What a nice and almost easy explanation you have given , though Quantum Physics is not an easy topic...

This is the best TED talk I have heard in Tech

Yeah, that didn't really explain it at all.

The reason why the quantum computer had that high winning rate is because the game was played in its world. Secondly, it has full control over its world and knows how to get what it wants with what it has. Hence, it will always win any game it plays. That is one major problem of humanity. Lack of absolute control over our world due to very high uncertainty about the future. That is why we plan but may still not achieve the desired target due to unforeseen circumstances. This technology has so much potential!!!

can this be used to send quantum messages to look for other life forms in the universe ?

So what you are saying is quantum is all about uncertainty. I got it. A mad computer.

The exact explanation of quantum computing is beyond our logic!!!!!😶😶😶

the end of the speech is really beautiful

The Q-computer prepares the initial state as |Head> and plays first by choosing either to flip the coin or not, but the outcome is not revealed to the opponent - not even to itself! The opponent plays in the second place akin to the Q-computer. Finally, the Q-computer plays, which is also a measurement revealing the outcome … it’s |Head> and hence, the Q-computer wins, not once, but in every round of the game. *** If the opponent plays first choosing the |Tail>, then obviously, the Q-computer loses every round of the game … which is not all mentioned in this video presentation!!! *** |Head> is like the |y; spin-up> state, prepared initially by filtering it out from the Stern-Gerlach (SG) apparatus with magnetic field direction along Y-axis, by blocking the |y; spin-down> component. The |y; spin-up> state then passes through two sequential SG apparatuses [1], but without undergoing any measurement. The magnetic field directions in these two SG apparatuses can be arbitrary. The output from the 2nd SG apparatus is subjected to a measurement by the Q-computer using the final SG apparatus with magnetic field direction along Y-axis, akin to the initial SG apparatus. It’s very clear from the quantum formalism that the two sequential SG apparatuses in between the initial and final SG apparatuses, simply play the roles of identity operators [1], i.e., every time the |y; spin-up> state passes-out of any one of the two sequential SG apparatuses, it’s in the same |y; spin-up> state and hence, the final measurement obviously results in the |y; spin-up> state. Actually, the presence or absence of the in-between two SG apparatuses doesn't matter, because, they don’t perform any measurement. Therefore, the play of Q-computer and the play of opponent are just dubious. In fact, in the case discussed in this video, the Q-computer never performed any quantum computation for winning every round of the game. In other words, it's a game played by the Q-computer with itself = A self-goal (OR) the opponent must be an ignorant to loose every round of the game, because, when the Q-computer shows the initial state, then that's the state to be bet for a win. Reference [1] J.J. Sakurai, Modern Quantum Mechanics, p 33 (Addison Wesley, 1994).
