Until observed lol

Sounds like CHEATING

Yes

Not really, it's more like the computer is flipping the coin around an axis you didn't know existed such that your flip makes no difference. Then it flips it back at the end

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

Its a scam. This "Quantum Computing" is a $$$Grant siphon that has been around for decades. They use the same talking points and simplified tech analogies as talking points to fool the unscientific liberal class and their journalists. I've never seen them offer a publication on machine coding for controlling the quantum state inputs and outputs. They show up about every 3 to four years to appeal to new audiences once the old ones forget.

​@@CHAS1422 But actual viable quantum computers appeared only few years ago. If you are not satisfied with explanation for idiots, then stop watching them. Research the topic, for fuck's sakes.

@CHAS1422 You really think people decided to spend their entire lives studying quantum physics and computing as an elaborate scheme to make a modest income off of research grant money? Even one person doing that would be ridiculous, but for it to have lasted this long a large portion of the global scientific community would have to be in on it. We're talking hundreds of thousands of people working in secret, all over the globe, coordinating, falsifying documents, faking research, intimidating and getting rid of possible whistle blowers, all for what basically amounts to a public school teacher's salary.

That's what I was looking for. She just talked about applications.

She wasn't supposed to be speaking about circuits of the computer. And yes, thats how it works. The super position is the only concept that people dont understand. She was there to explain that, not the components of the computer.

It’s explained in this this video using the cat in box thought experience. kzfaq.info/get/bejne/obqIh7OWmN3FmJc.html

They don’t want you to understand how it works because then their secretive trillion-dollar technology is worthless if regular people understand it.

@@justintimmons7613 There are loads of free textbooks and video lectures out there so that anyone can go understand it. Quantum physics and how it applies to quantum computing is not secret or protected information, It's just really hard to understand. They probably could have had a better demonstration of how qubits work but it seems like the goal of the talk was more to just show what the technology will be used for. And even if it was all about how it actually works, this video is way too short to explain it well enough to compete with IBM lmao.

"I think I can safely say that nobody understands quantum mechanics." -Richard Feynman, often considered the father of modern quantum mechanics.

Or it's a joke, because of the particle dualism. So when you are getting it, you are not getting it?

Open a book of quantum physics and try understanding a concept or two and you'll get what she's saying. And that's because Quantum physics or quantum computing seems to defy the common sense and experiences we come across in our daily lives. :)

Yeah, well said but quantum computers aren't useful for chemistry because they make use of the same strange quantum behavior present in atoms and molecules . They are useful because quantum computers are theorized to be able to tackle problems of a computational complexity which classical computers can't solve in a reasonable amount of time. Quantum Computers offer a computational speed up with respect to classical computers which makes these complex modelling and simulation problems found in the fields of physics and chemistry feasible (at least in theory).

Exactly! So y is every1 like 'wow' That's so brilliant?!? It's simple - ur right it's cheating!

I think the same...

It didn't cheat, she just didn't explain it well. The computer obviously would have used quantum entanglement. It entangles the coin with it's own copy, so no matter how many times the original coin is flipped, it can check it's own copy to determine the original's state, without looking at the original. So yes the coin is flipped, and it does have a set state at all times, the computer just doesn't care what that state is, and from the computer's perspective it's just a probability until it checks to see what it really is.

@@dirkwalker9686 This is still cheating, I think. The rules of the game are 1) no looking 2) flip it or not. Entanglement is not on the list, and it is an extraction of information. I guess the game has to be simplified so much for the audience. And for the presentation: she starts with analogue computing, then does not explain why the game was changed, then she repeats all the hype's promises / bullshit bingo that circle around (the public perception of) QC. IT security is covered and understood very well, it's just complicated, expensive and not a priority. Except the claim that real QC machines are supposed to kill all of our encryption.

@@dirkwalker9686 Obviously it cheated. It's the fact that it can cheat it's way out of a 50/50 probability is the impressive part, not that it defies maths

The answer to that is maybe.

​@@conwaymj88 I assume the quantum computer entangles the coin at the beginning, so regardless of how many times the original coin is flipped the copied entangled version that it keeps track of will have the same value. So it can perfectly guess the value of the original coin without looking at the original coin. Though, If that is how it work's, it would have been nice for her to explain it.

@@dirkwalker9686 but that contradicts the games rules, in that the state of the coin after the player's turn is not revealed to the computer.

@@mintysingularity thats where your getting confused, rightfully so, not explained well, it doesnt win by waiting for an answer, it can play both answers at the same time, its capable of holding mutiple answers, as opposed to binary thats only capable of 1 answer, "o" or "1," quantum can use both at the same time, and more. thats the point, she just doesnt explain it very well. its all very complex, not something that can be explained in 10 minutes i dont think. but the easiest way to compare is the binary code for "M" is 01101101 this means the computer has to use a circuit to turn on and off electricity multiple times (8 times, 8 bits) to relay the letter M through the system, quantum doesnt have to, using its super position states, it can relay all that information in 1 go, much faster binary. the short of it is, quantum is not restricted in only being able to produce 1 of 2 options as it computes. the confusing part is that its not cheating by using both answers, only one answer is used, but it still plays both answers as a "state" ...... and thats where any physicist will start to lose you, this is where it starts to get really complex....

@@Reazintful no, I'm not confused. It's simply a very bad choice of example/comparison. Without additional information, the theoretical coin flip is always 50/50-the games rules are being broken for the sake of entertainment.

😂😂😂

@Maetapong Oun Upatising, i think you are wrong. She explained it perfectly well. Look into the Heinsenerg Uncertainty Principle. It will help you to further understand how quantum computing works.

The teleportation communication could have been used in an analogy for a better example

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.

it's a fpoon

@@GoldenMoments100 Would love to see you on KZfaq discussing this!

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.

Haden Snodgrass I don’t think she would have explained it as well as you did x

From what I understand, it could also exponentially improve deep learning systems or even create a new breed of Artificial Intelligence. In apps, robotic aids or even computer games. What I also find interesting in our quantum world is the quantum entanglement bit. I imagine that it could be used for deep space travel and later on for communication between colonies in the far far future (if humanity ever gets there).

@@DeltaNovum You can't actually use entanglement to transmit information faster than light. When you measure one qubit it will be in one of the two ground states, according to a probability. This means you can't choose which state it ends up in. This means that the other entangled qubit is also in state 0 or 1 randomly, dependant on which state the first qubit collapses into. Both parties would have a randomized key which carries no information.

Why do u spread misinformation? When qc will have enough qbits they will be way faster than regular ones in every way

None of them would have an edge. An optimal strategy for both is to apply a uniformly random unitary transformation to the qubit, leaving it in a random state. When you then measure it you will get 0 or 1 with equal probability.

The one with more number of boundaries

The one who will have the last turn.

The one that doesn’t fail, it’s uncertain that they will work at their best, so the one that falls behind will lose

Frank Maclow So wrong! Quantum physics makes all the sense there is. The only thing about it it’s defying our intuition. Check for instance just the principle of uncertainty of Heisenberg. It’s really a principle that defies our intuition but after you understand how is that possible you will come to the point where it makes all sense.

I am 12 and I understand

It was Bohr not Feynman. And it is a stupid sentence if taken seriously. Quantum mechanics makes complete sense but it has loopholes which, because they are difficult to manage mathematically, are left open and idled. Fortunately not all physicists are so cynical and some have proposed alternatives to Copenhagen.

@Aufenthalt Good Morning to your brain, it was Feynman. Maybe try to not spit out your opinion on something that you didnt even fucking spend 3 seconds of googling on. However, youre coming out even more stupid with your last sentence. If you meant Bohr, he was the one who worked on the Copenhagen interpretation of Quantum mechanics with Heisenberg. Thus, youre not only saying wrong things but also contradicting yourself mate.

Define understand

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.

@@Wiseindy Agreed :) Let me know if someone can explain how this can be used for computing. Until then I am assuming that the qbit-guys may have the wrong idea.

@@matrixarsmusicworkshop561 How was it contradicting?

@Matthew Garrett I have a few questions. Why can the particles A and B as you called them not travel faster than the speed of light? And how because of this does it mean that it's useless for teleporting or transmitting the information?

Faz Naz123; the instantaneous collapse of the distant entangled partner particle does not transmit information. One gets one spin and the other gets the opposite. The angle was pre decided and traveled with the particles at the speed those objects can travel which is less than "c".

@@faznaz7455 You can already teleport information with the speed of light. That invention is called "the radio". Has some fancy implementations too like the cell phone, TV and sattelite communication.

Exactlyyyyyyy😂😂😂

She did perfectly well. Quantum computing smells like cheating in such scenario only because the state of the subatomic particles cannot be fathomed.

@@boulevarda.aladetoyinbo4773 No she did not. She said the computer can chose to flip the coin or not. But the computer does not do that. It puts the coin in a state where the humans choice will not matter and then it will just put the coin out of that state and it will be heads again. See source code here: github.com/MackEdweise/TEDxCoinToss

Here after this year's Nobel

And ?

No it doesn't check...but actually never changes. Basically it stays in partial head and partial tail. But at the end transforms too completely head which is the condition of the game for the computer to win.
