its funny because the "spin up and down" is only a small part of heisenberg's probability function. You need shape, size, spin, and hybrid information to get the probability of a VECTOR. The output of a qubit is not a probability up or down. its the probability that its in a specific location relative the core of the atom. So the output instead of a 0 or 1, is a 0 or a 1 plus the Vector location where it has the highest probability it can be. Yes the primary usage of the Vector is to get the percentage of up or down, but the percentage is not the output. to get the percentage you need to know the highest probability of where it is first.

It's like you have a switch like in normal computers, 1 is on and 0 is off, and superposition is when you get it just right in the middle, where it is so unstable that just touching will make it snap back to on or off. Basically, since you have 3 states, and normally there are 2, you will find that there are more ways to arrange 3 states compared to 2, so it's like needing less people to do a similar job. Similar to the real world, it takes a lot of effort to keep the switch in the middle position, and so quantum computers will not replace classical computers soon. (Unless room temperature superconductors and other special materials are invented.)

Nah, quantum mechanics go against all basic knowledge of the human mind. It's possible for things like one thing being in multiple positions in multiple states at each position at once. Teleportation is possible in the form of quantum entanglement. In fact quantum mechanics actually states that there's a probability you could be teleported to anywhere in the universe at any moment, only it'd probably take the lifetimes of millions of universes for it to occur once. It's a lot to wrap your mind around but amazing if you can break into it.

Quantum computers use atoms instead of transistors. A qubit, the quantum version of a bit (0, 1) can be in three states. (0, 1, -1) -1 is not a normal state, it is in a super position of the states 0 and 1 at the same time. Reading the state also means the state is in a classical state also. The thing we also use to get that 0 or 1 or -1 is the spin of something. It has nothing to do with spinning really. Kinda? You decide. en.wikipedia.org/wiki/Spin_%28physics%29 Exploiting that we solve "really hard" problems. The thing is though you need to make a quantum algorithm to actually solve the problem. Also, all quantum algorithms can be done on a normal computer. The reason we don't is because it would take trillions of years, but we could do it.
@DMitsukirules9 жыл бұрын
The Addiction 2 Part of the problem with teaching quantum physics is it's explained poorly and always explained in a way that makes it seem to "go against all basic knowledge of the human mind." It really doesn't. If you explain to somebody classic relativity (not even Einstein's, but Newton's) it went against all conventional wisdom that was thought of before. These things don't go against basic knowledge of the human mind, but perceptions people hold growing up. If you indoctrinate children to think about how the world works, including on a quantum scale then they will blindly believe it and see it as intuitive.

Meaning we feed it some input, where it quickly grows beyond what humans (and classical computers can possibly handle), but the final answer can be something as simple as 1 bit. eg: Something as simple the Boolean Satisfiability Problem,The input is finite (just a boolean function).yet as we try to solve it, it is pretty much impractical on classical computing, but what the final answer of such a problem is some as simple as "true" (yes it is satiable) or "false" (no it is not)
@TheMajorJF9 жыл бұрын
Is that the same as the halting problem? What I meant by programing is that, the system still needs to be primed before the calculations can be done. And part of the issue in learning how to code for a q-bit system is you have to just try things and wait for the entire program to finish before you can know if it is working or not. With classical programing you can have little display output tags just showing onscreen so that you can see where the program fails.
@skifree09 жыл бұрын
TheMajorJF Its actually very easy to verify if a computer is correct. All you need to do is feed it a NP-Complete problem. Boolean satisfactory problem is a very good example of that. It is non-deterministic in finding the solution, but say we do have a solution, it is very easy to check if it is correct. for instance with BSP, the idea is that Say you have a series a boolean Statement like (A and notB and C) or (notD and notE and C) or (C and notD and B) or ........... and this goes on and on and on. The question is that, Can this statement be satisifed. Ie: is there some assignment of the Variables such that The final result = true. for instance ( A and B and not C ) that is satisfiable if A=true B=true C=false. But something like (A and not A) no matter what you do cannot be satisifed. The problem is coming up with a "solution" reqires brute force, which quickly becomes O(2^n). Yet, the verify, we simply have to plug in the "solution" given, and see does it = true. as for halting problem, that actually something else entirely and deals with decision problems.

No. The claims of potential with Quantum Computing are so unbelievably inflated that you'd assume they Quantum Computers are the next coming of Christ. Brute forcing a 256 bit AES connection is still beyond impossible. The keyspace is unimaginably large. This is from wikipedia: _"AES permits the use of 256-bit keys. Breaking a symmetric 256-bit key by brute force requires 21*e*28 times more computational power than a 128-bit key. 50 supercomputers that could check a billion billion (1018) AES keys per second (if such a device could ever be made) would, in theory, require about 3×10*e*51 years to exhaust the 256-bit key space."_ Because of the Landauer Limit, the amount of energy needed to perform this computation is on the order of the amount of energy expended by over 100 billion supernovas. This is more energy than exists in the Milky Way Galaxy. The algorithms that are used as prediction models for superposition all come out to slower performance than conventional computers with the exception of one. This technology, if it proves to be useful at all, is at least twenty years away. Not only do people not fully understand how to build a proper Quantum Computer yet, they don't even understand the theoretical framework behind a theoretical computer; let alone the practical obstacles blocking it.

"What does theoretical physics have to do with improving processor performance?" Pretty much everything. There'd be no transistors without the discovery of quantum mechanics c. 1926, which is part of theoretical physics. I'm sure physics (condensed matter physics, too) helps improve non-quantum processors. Also helps with hard drive space. Electrical engineers make use of theoretical physics -- in particular, Maxwell's equations and the Lorentz force law, and their consequences. And there's a lot more, but that would veer off topic too much.

So, given my limited understanding of this please feel free to correct me if I am wrong, but quantum computers will never be consumer-grade capable, due to the need to supercool the atoms involved, and because a consumer won't be interesting in more accurately researching weather patterns. But then, what is the future of consumer grade computing? We're reaching the peak of Moore's law soon, with maybe 8 years left before it simply becomes impossible to shrink the manufacturing process down any further because of electron resistance and quantum tunneling. What comes after that? Will we just be stuck at that level of processing power? I guess it's not such a terrible thing, it'll still be fast, but there's got to be a way to breakthrough this barrier.

Here is my short explanation: Having 4 qubits = needs 2^4 probability amplitudes to describe each state: a1 |0000> + a2 |0001> + ...... + a15|0001> + a16 |1111> = 2^4 pieces of information in 4 qubits Quantum computing operators act on individual bits, but they are actually manipulating 2^4 probability amplitudes at same time

when i was at University i wrote my dissertation on Artificial Intelligence in games, namely proactive persistent agent architecture. basically brains for npcs, using a combination of scheduling and a neural network. this kind of computing would be amazing for AI, as nearly all computation time is taken up crunching floating point variables for fuzzy states.

Great video guys, but I'm a physicist, and you made one mistake that just so happens to be a pet peve of mine. Electrons don't actually spin. The quantum property of spin acts a lot like a normal angular momentum created by a spinning mass, but there are a few things that prevent it from actually being that. The first problem is that electrons don't have a volume, and for that matter no fundamental particle's do. So it doesn't make sense for something with no shape to spin. The second, and related problem is that if the electron were actually spinning and did have a volume, then it's outer most points would be moving faster than the speed of light for it to generate angular and momentum of it's spin. It turns out that all fundamental particles have spin, and it's actually a fundamental property of the particles. Essentially, it's an amount of angular momentum that the particle always has, no matter what. It's a really strange thing to think about, but it turns out that the universe works this way. Keep making great videos guys

I like Schrodingers Cat is a good example of something being in two states simultaneously. A cat is penned up in a steel chamber [from which no information can escape, no sound, light, radiation, or other form of information], along with the following device (which must be secured against direct interference by the cat): in a Geiger counter, there is a tiny bit of radioactive substance, so small, that perhaps in the course of the hour one of the atoms decays, but also, with equal probability, perhaps none; if it happens, the counter tube discharges and through a relay releases a hammer that shatters a small flask of hydrocyanic acid. If one has left this entire system to itself for an hour, one would say that the cat still lives if meanwhile no atom has decayed. The psi-function of the entire system would express this by having in it the living and dead cat (pardon the expression) mixed or smeared out in equal parts. Quantum Physics is a very strange and interesting field of study.

Okay, a few things. I think you got the energy levels of spin up and spin down reversed. Where in a magnetic field spin up is normally defined as the spin that is aligned with the magnetic field. As a second point, diamond semiconductors are looking like they will be the next step in personal processors. This is mostly due to the melting point being pushed away from 128*C up to around 450*C.

When you say that gravity would be working it's hardest at the apex of the swing that's actually not true, in fact the force of gravity would be the greatest during the LOWEST point of the swing, since gravity is inversely proportional to the square of the distance between the objects it is acting upon, and technically at the apex you are farther from Earth...

Almost correct. Not the number of processes is high but the way it works means an algorithm can be ran for EVERY data of a specific size (i.e. number of qubits) AT ONCE. This is what makes QC especially useful against RSA and public key criptography itself.

I think this video was lacking a bit of key information so I just want to clarify. A qubit got four positions while two of those are superpositions, while in theory these two superpositions are capable to hold information though something quantum computers still struggle to read and write. That means that a single qubit can hold four positions instead of two positions in bits. This is NOT just doubled the information as we can see when we factorial bits and qubits, four bits would give 16 different possibilities while four qubits would give 256 possibilities but that's not everything, qubits can be quanta entangled which means that two qubits are entangled and by measure one you measure both that got the potential of a single pair of entangled qubits to hold 16 positions of information at once and if we take four of these pairs we got 65536 different positions and while in theory it should be possible to form pairs of entangled qubits far more than just two, like if four qubits are entangled in four pairs we're up in tens of billions of positions but that technology may not be possible and if so, very far away. To roundup, quantum computing is still in it's infancys and there's lots of problems to solve, physics to be understood and discovered before we can really take advantage of the qubits superpositional properties. We also need to solve how to isolate the qubits so they can't escape the system, this is also a very fundamental property of qubits, they can pop out of existence to reappear somewhere else in something called quantum tunneling, this is also the reason why there's an absolute minimum size of a transistor as when the walls gets to thin quanta may just tunnel out of the system.
