You said "ions are atoms that are missing some electrons, so they're negatively charged." Wouldn't they be positively charged?
@bill39211 ай бұрын
Metal ions are always positively charged. I know this because metal ions always accumulate on the negative electrode within an electrolysis setup. Non-metals reacting with metals tend to gain or share electrons to form anions which are typically negatively charged. It gets complicated as there are elements that are called metalloids and their characteristics fall somewhere between a metal and non-metal.

@djangogeek11 ай бұрын
@@davedouglass438 Entanglement does not disrupt superposition. Entangled states are a specific kind of superposition state that can only be formed in multi-particle systems. You might be thinking of decoherence, which is the process of a quantum state decaying into noise. Quantum computing relies on being able to manipulate your system into any quantum state you choose. So both superposition states and entangled states are necessary for quantum computing.

She ´s a bit my hero, and I like to hear her opinion on all the topics, she picks, even if it differs from mine. Anyway, many of the commenters have factual arguments and don´t belong to the professional haters or idiological blinded ones. Sabine made two brave and honest attempts, to get it right, one was that pinned thread, the other one, I think, was the two weeks later vid about communication in social media and her role as "influencer". That was good. Three points, I´m personally still worried about: 1. She harmed herself and the reputation of her great and important work with that, that´s sad. 2. Her shot on Thunberg was an unrepaired mistake in my opinion, regardless of what that girl says about economy, and how substantial it is. If you claim "don´t trust her", most people will transfer it on her commitment about climate change, and Greta did a brave job in creating the fff-movement, that brought this existential problem in the minds of more people in the last decade. As you know, Sabine is committed and worried about that too. Well, Greta is not Elon Musk. 3. As you can see in the comments, she opened a political camp-thinking with that, that´s unworthy her free-thinking and open-minded spirit. It doesn´t solve problems, but creates new ones and seperates people instead of bringing them together. Ok, this new video here is great again, I´m a bloody layman in that topic, but could follow and learned a lot. I enjoy my "parasocial" relationship with her. Have a nice and peaceful day.

I must've spent an hour defending you from all the nitwit casuists in the comments. They probably thought I have a crush on you, or something. Let 'em, because I do. But with your brilliant brain you could not only shoot down his arguments, you could blow them clear outta the fcuking sky.

The situation described at 3:15 exemplifies what often happens when a disruptive technology is introduced. While there may have been a bit of spin involved, I don't think that Google was gaslighting everyone on the comparison. Instead, often just the mere introduction of a disruptive technology can highlight areas for improvements in the incumbent technology. I suspect the Chinese scientists went back to understand how the Quantum computer was able to compute faster, and then took these ideas as guidance on how to improve a traditional computer and software. Voila! They are able to shrink the gap to quantum computing. Other examples of this technological phenomenon are the improvements in the efficiency of internal combustion cars after the advent of electric cars, and the improvement in the performance of passive suspensioned F1 cars after the introduction, and then banning of computer controlled active suspension F1 cars.

One thing which is tagentially related to this is that the field of programmable photonics is really maturing a lot and we're about to see "photonic FPGAs" pop up. Those have the advantage of: 1) Being very good for rapidly prototyping conventionally useful photonic devices like the ones used in optical fiber networking equipment, and 2) Giving a computational advantage when considered just as analog computers without the quantum parts, since they are good at analog matrix multiplication in ML applications (but are very bad at doing anything nonlinear) 3) Doing some slightly quantum tasks like quantum key distribution that don't rely on having a full quantum computer. Quantum key distribution is something we've been able to do for a long time, but mass producing a programmable silicon photonics chip for fiber routers that can also do QKD would be a pretty major development. It would also mean that quantum computers developed later on may benefit from quantum capable fiber networks already being in place, which increases the probability that quantum computers end up being useful (networked computers are a lot more useful than isolated ones).

One point that's quite important regarding comparing different platforms is that they have different ways of connected qubits. Superconductors and semiconductors are limited by the 2D surface they're machined on to, so usually qubits can only entangle with their neighbours. We can use these connections to make longer ones, but that introduces quite a lot of noise. So it's not just about the number of qubits, but how well they can interact with all the others.

I had an idea for a science fiction story involving Artificial Intelligence. (Quantum Computing?) If they made it into a movie the space craft would look something along the lines of the Avalon from the movie Passengers. The ship could only speed through the vastness of space with the aid of artificial intelligence that would accurately predict objects that would conflict with their flight path because no radar or other sensor could see far enough in advance to be useful. The premise would be that the artificial intelligence would sound an alarm and wake the crew with a warning of an impending collision. BUT.....simultaneously there would be a mechanical malfunction that keeps the ship from automatically taking evasive action. So what, you might ask? The trouble is that this occurrence is unprecedented in deep space travel over hundreds of years.....and the crew no longer has the skills to make the repairs. Thus, the rush is on to learn the skills and repair the ship before they collide with the object. All kinds of twists and turns possible there. At first the ships computer works against them.....because it is malfunctioning. They realize they need to wake certain passengers who might have the intelligence to help save the ship. They have to decide between one of two repair plans because they don't have the manpower or time to pursue both plans. Repair the A.I. so it can resume normal protective operations or learn to repair and pilot the ship themselves. Long story short......they fall short of the deadline to set things right. They prepare for the collision and their demise. By then they have learned how to bring the surveillance systems alive and monitor their own doom. The screen images are generated through the ships computer. The object comes into view. It moves closer and closer. It looms large on the screen and impacts the ship......only nothing happens. The computer was wrong. There never was an object hurtling towards them. It was an erroneous prediction. The happy ending is that they learned how to learn again. How to be human and not children of artificial intelligence.

the trick is simple, information about the outcome is transfered to the partner before its measured, thats all you need. and before, after and the direction of causality is ambiguous until you can measure a broken lorentz symmetry. the first particle measured is always A in my explaination, according to whatever foliation you think is true, prefer is true, but until we know how to differentialte its going to be just musings about it.

true, quantum computing is not a replacement for modern computer as most of what we process today are logic not math. the ability to process certain thing very quickly is still very useful.

Yes it's more comparable to a GPU, not "general purpose" but still useful, and there's no doubt in my mind if we ever got the point where they could be as consumer accessible as a GPU, then clever software developers would find ways to make use of them to optimize various kinds of everyday tasks in ways we can't even imagine. That is a big if, though, if something like photonic chips actually are scalable and quantum computers aren't just stuck as some room-sized near zero kelvin computers forever.

Nothing on semiconductor spin qubits? The architecture of these qubits is very similar to conventional semiconductor transistors, therefore i feel like they have a lot of promise for scalability.

03:22 Don't understand "53 QUBITs", meaning (53×4)= 212 bits (which is too unfamiliar/strange for/in normal Binary system) It should be "64" QUBITs, meaning (64×4)= 256 bits, in Binary, (0 &1).

Wonder if just doping one ion in a waveguide can perturb the unbound spin orbital and have a magnetic field realignment to store information like a hard drive. Would need temperature affects minimized but temperature minimally affects the photon group velocity although modulators are temperature sensitive to phase shifts.

Being a researcher in topological computing I can safely say that process is slow in developing base technology for topological computing but it can easily extended for large qubit systems as their resilience to errors like defects or disorders in chips or due to environment borne.

I believe what she meant when she said “with entanglement you can encode a huge number of states” is qubits can exist in superpositions. A zero and/or one

I wonder how long it'll take to produce a HAL-9000. In "2001: A Space Odyssey" (1968), David Bowman is shown deactivating HAL-9000 by pulling out his photonic memory modules. Interesting enough, that detail is only depicted on the film, Arthur C. Clarke's book (written after the film's script) doesn't mention it (although it mentions that the monolith has perfect reasons between sides in more than three dimensions...)

When are we going to get back to physics questions? Enquiring minds want to know, for example, whether, in regards to entropy, whether the entropy of the combined system, obtained when two black-holes are allowed to interact thermally, is never greater than the sum of the entropies of the individual black-holes; or can never be inferior to the sum of the entropies of the two subsystems. is S [ß, E, V] less than or greater than S(ß (El),El,V1) + S2(ß (E2), E2, V2) = Sl(E1,Vl)+S2(E2,V2) ? For Black Body radiation we have S{E, V) = 4/3 b^1/4 E^3/4 V^1/4 , where V is the volume of the cavity and cb/4 is the Stefan-Boltzmann constant. Planck found it consists of the expression for the entropy as a logarithmic function of the number of photons in a given frequency interval of the electromagnetic field. [ which implies a power-law distribution for a large but finite heat bath. ] The entropy of black-body radiation is, therefore, extensive; no increase in energy or volume can destroy its extensivity since both these quantities are, themselves, extensive. These are the types of question, I, at least, am interested in.

PS Simulation of topological particles on error prone (non-topological) hardware will never give you topological protection. As for true topological systems, without a gate or any kind of operation, you can not calculate anything. Companies pursuing topological approaches should be predicting when they will achieve a single qubit that they can manipulate. Then they have to show it is actually immune to noise. Maybe one of those in 10 years? Ah, yes and then you have to make two and do two-qubit gates...

What I never understood, what do you do when the quantum state is destroyed? Do you have to physically open and reset the chip in some way (repair?) or is it just a matter of pressing restart in the specialized software?

You do the measurement process before that. You prepare the quantum state at the begin of each quantum run. Orchestration is classic.
