I've read and watched every single possible explanation of quantum computing and it always comes to "Imagine you can solve every problem in the universe in 0.00001 nanoseconds - well that's what quantum computers do". Seems like they miss a step or two, seems like promotional videos to me. I love this one: every qubit can be both zero and one at the same time - so you have a right answer every time - huh? So it produced random crap?

You stole the words from my mouth. I was about to write a veeery similar comment :) I'm watching these videos and shake my head in disbelief that none of them mentions the KEY point that is - Grover's Operator, without which everyone who's new to quantum computing will be left disappointed saying "but but but...HOW DO WE ISOLATE THE RIGHT ANSWER FROM ALL THE BILLIONS AND BILLIONS OF INCORRECT ONES!?!?!? it would still take n amount of steps, wouldn't it!?!?". And surely that was my frustration when I was learning about quantum computing. Conclusion: people are TEEEEEERRIBLE at explaining things to newbies and oftentimes they don't even understand the concept themselves but just regurgitate what has been already said. This guy however is one of the rare ones who is good at explaining things, he thinks clearly, logically and in a "step by step" manner. My only complaint is that he didn't explain Grover Operator briefly just to make sure that the newbies to quantum computing understand the ENTIRE concept of how quantum computing works. But hey, at least there should be no "but but but but...." moments after his video for whoever knows the basic principles of quantum mechanics.

Lots of mixed comments in here, some saying things along the lines of "at last, I understand!" while others are saying that I've not explained anything. Clearly, the video is perfect for some groups but not others. This video is for people who seek a basic understanding of the concept behind quantum computers, rather than the technical and mathematical details or quantum theory. For those looking for more details on the Grover algorithm, but still intimidated by all the equations of Wikipedia and other online sources, read below: It's true that I don't go into the depths necessary to fully dissect quantum computing - that would require a good chunk of time spent on quantum entanglement, spin of atoms, quantum probabilities, and walking through scenarios of qbits and how the Grover algorithm iterates until it finds the solution with high degrees of confidence. Suffice it to say, the Grover algorithm works because quantum particles are entangled - they are related to each other. So when you observe one outcome, you can make a guess with much greater probabilities about other outcomes - due to entanglement . This allows you to guess your answer far fewer times and arrive at the answer with a very high (though not 100%) confidence than just random guessing using a traditional computer. I recognize that's still an inadequate answer that uses no math - but hopefully that will be enough for most of you. If you'd like me to make a video series to go from beginner to quantum computing professor, let me know :)

I think it's a bit misleading to say a quantum computer can process every possible input at once. While you can operate on all 2^n possible inputs of a sequence of n qubits at once, a measurement of the state of the n qubits will collapse the superposition to a single possibility. You cannot in general get the results of every 2^n operations with only a single iteration of the operation. Even Grover's algorithm, mentioned at the beginning, will not find the correct password immediately: on a classical computer, if there are N possible passwords, then it will take at most N tries to get it right, but on a quantum computer it will take as most the square root of N to get it right. Certainly a speedup over the classical algorithm, but still not instantaneous. Quantum computers are unfortunately hugely limited by the fact that measurement collapses superposition states. They are not as powerful as you might think. There are, however, some cases in which it is possible to use quantum mechanics to your advantage to gain a speedup over a classical algorithm, some of these with drastic consequences (look up Shor's algorithm).
@JG-Zonic

OK, I think your comment is pointed at the question that I had while watching the original video. Unfortunately, my understanding of the material is not sophisticated enough to understand completely what you just said though. My question is: how come it's not instantaneous? As in the video, if the Q-computer will try all possible solutions at the same time because each bot can be both 1 and 0 at the same time...where is the time loss? I have a feeling this could devolve into an existential issue. LOL Anyway, thanks!
@carloshoratio5100
7 жыл бұрын
So a quantum computer can, in a sense, try every possible solution simultaneously, but you can only actually observe the results of one guess because measurement of the qubits' state collapses the state to a single possibility. In order to actually gain useful information from the quantum computer, you would have to run the operation multiple times. As an analogy, imagine you have 100 coins and you want to count up the number of heads and tails. But, every time you look at one coin, every other coin gets tossed again. You can toss all the coins at once, but you can only see the outcome of one of the tosses without changing the state of the coins. In the case of guessing passwords, in order for the computer you're trying to break into to determine whether the correct password was given, it must measure the state of the input qubits. So even though you have set up your qubits to be in a superposition of all possible states, including the correct password, only one will be "chosen" to go through to be tested. There is a way to use a quantum computer to guess the correct password in fewer steps than a classical computer could. It's called Grover's algorithm. It cleverly gets around the limitation of superposition collapse in a somewhat complicated way that I don't quite remember. But it cannot find the password instantaneously. And by instantaneously I really mean in constant time; a "constant time" algorithm is one that take always takes the same amount of time to complete, regardless of the size of the input. The time it takes Grover's algorithm to complete is proportional to the square root of the size of the input, which is still faster than the fastest classical algorithm, which takes time proportional to the size of the input.

No problem, glad that helped! Grover's algorithm is really just an example of one thing a quantum computer can do better than a classical computer. I would suggest learning more about the basic structure of quantum computing before trying to tackle any particular algorithm. Once you are comfortable with the underlying math, quantum logic gates, and measurement, then you should be better equipped to deal with Grover's and other quantum algorithms in detail. I'd recommend David Mermin's textbook on quantum computing for a good introduction. It's aimed at junior/senior level undergraduates in either computer science or physics (it does not assume specialized knowledge of either field). It may be a bit difficult (I don't know how much math/physics you know), but if you're feeling up to it it's an excellent introduction.

This "Grover operator" is not a fundamental feature of quantum computers; it's just part of one specific quantum algorithm (Grover's algorithm). Essentially, Grover's algorithm finds the unique input of some unknown operation that produces a certain output, for example the unique password that gives access to the computer. The Grover operator is just the set of operations that make this work, analogous to a circuit composed of logic gates in a classical computer. Quantum computers can do many other things as well! Unrelated to Grover's algorithm, we know whether a qubit is 0 or 1 by measuring it. How we measure it depends on how our quantum computer is physically representing qubits. One possibility is to encode qubit states into the spin of a photon. We have ways of measuring a photon's spin, so in that case that is how we would determine the state of a qubit.

You've not really explained anything Sean Ong, you just punted the "magic quantum" solving onto the "grover operator". Unless you explain how a problem can be solved you're just making the same "magical" claims about quantum computers. Get into the nitty gritty details please. For example how would a quantum comptuer know what the four bit, 0000 through 1111, password is? Without knowing anything about the password other than the four bits you can't know which of those 16 possibilities is the password. How would a quantum comptuer know the contents of the server's memory that stores the password? See the problem with your example now? It would be really nice to see a real example using just six or eight qbits compared with a real program of a classical comptuer used in a video in such a way as to not rely upon the leap of quantum magic faith. Explaining a concept, which your video does very well, isn't the same as explaining how it works.

Traditional computers take each input number and compare to the computers memory to get a match. This takes a long time because each possible combination has to be tested. Quantum computers are able to input a landscape of numbers rather than individual numbers. So the number you are comparing to stored memory is always there, you just need to strip away all the wrong answers. As an analogy: Imagine you have a magical quantum key, that you place into a lock, the lock impresses the key code onto the magical quantum key and so now the key is the correct key therefore it unlocks the lock. The key to this( no pun intended) is knowing that the solution to a problem is always in the quantum number, now all you have to do is collapse the function to reveal the correct answer, the correct answer is impressed by the very solution you are looking for. Now thats the way I see it, not sure how physically this would happen in a quantum computer though?

I get everything except for the Grover operator. Oh - does it do this --> correct_answer G current_qbit_state? Where "G" is the place where all the combinations can be seen? Is it implemented in hardware or software? Has it actually been built yet? Is it just math with no real world implementation? P.S. I looooved this video.

Thanks Sean, best simple explanation I have seen todate, if that is even possible. l love your analogy of a spinning coin representing both answers at once, until it is stopped/observed.

If the quantum computer can crack any existing encryption, that is a problem.

And it can make strong encryption to replace the current encryption... It also checks for strongest possible encryption with its same quantum power!

Thank you for the explanation - it was for sure simpler than all others I have watched. I think I only grasped half of it though. I learned: The querier computer (workstation) and the host computer (server) must both speak ‘Quantum’. Also, by submitting the 4 digit quantum binary string of “0 or 1” for each of the 4 digit places (0/1 | 0/1 | 0/1 | 0/1), it is only one question to ask “is the passcode any of these 16 possible values” and will get a discreet answer of “Yes”. What I missed: I don’t see how the querier is closer to learning the actual passcode of “1011” without still a bunch more passcode queries being submitted?

Quantum computing should be able to replicate the workings of the brains 86 billion neurons. Algorithms should be learn through exposure to all human information. Within a short time it would be impossible to tell if you were talking to a machine or a computer. We would be redundant

Before he explains how a quantum computer 'checks' all the passwords in one go, he has to explain how a _classical_ computer 'checks' passwords one at a time. _He hasn't done this._ What password, on what system, is the computer 'checking'? How does the computer _know_ which is the right one? Brute force trial and error? OK, but what meaning has that analogously with a quantum computer? How does a quantum throw superpositioned qubits at another computer brute-force-wise? It can't simply stare at some 4-qubit entity and determine the correct password unless it already knows the right answer _a priori,_ or can look up the answer in the back of the book. He needs to find a less hackneyed, and inherently opaque, example than "checking passwords"... such as the traveling salesman problem, where the best (or at least a highly optimal) solution is evident by comparison-checking.

Not bad at all. This is the simplest explanation (specially the spinning coin example). Good examples of the practical applications, but a better example of how it tried the multiple possible combinations (using Qbits) all at once would have "sealed the deal".

No A-HA at all, but still a good job done explaining a pretty hard subject for 'regular' people. Although i personally don't like the coin (aka 2-bit) analogy, since u can slow down (or freeze) or take a time-slice of the flipping coin and you would be able to tell which side (head or tail) the coin is in that particular time-slice, whereas for the 'regular' human eye it is way too fast spinning to observe precisely. All in all, well done Sir.

if this was a video about cooking the perfect meal, i feel the grover operation is like telling the audience 'dont forget to add this ingredient or the meal will be ruined' at the end, then not telling anyone what the ingredient was..

I don't buy the Quantum Electronics theory. I reject the idea that digital BITs (BINARY DIGITS) can be either 0 or 1 OR BOTH. Binary, by definition, can only be a 1 or a 0 and not at the same time because I know Solid State Electronics. The single element of a bit is the Transistor Circuit which can ONLY be either ON or OFF, but can never ever be both ON AND OFF. It all depends on how it is Biased at what level to turn on. 2^n where n = number of digits can provide a lot of information. So 2^2 provides only Four possible States. 2^3 provides Eight Possible States. 2^8 provides 256 Possible States Now I know that some electronics can be biased to have Three States. -1, 0, or 1. Three-State Electronics is possible. And 3^n where n= # bits can provide even more information. 3^ 1 can Provide Three Possible States 3^2 can provide NINE Possible States 3^86,561 Possible Stats as opposed to only 256 Possible States for 2-State Electronics.

The coin when flipped is not both heads and tails at the same time. It is flipping back and forth from heads to tails at a high rate making it seem it is both at the same time.
