The many worlds interpretation of QM

0:00 Let's suppose we know exactly what happens if the state is in with probably one artist this part is suppressed the actual set of the system side is equal to All of these terms are going to be represented by a spin-up of an apparatus, which is going to be a spin-up of an electron, which is going to be a spin-up of an electron.

2:30 So let's see what happens. All right, spin down initial state. And there's the same sort of arrangement as before. The front goes straight through. The state's on a vector. The spin state's on a vector. So we still have spin down. But what about the cat? Well, it's pretty obvious what's going to happen with the cat here. We haven't completed the circuit. The signal goes right through. The VBS is open and it's all over the cat. So we've converted the cat from the live state. This one-way measurement does not affect the system being observed, but you'll note that it generally generates an enormous effect on the measurement of the observing apparatus, the categories, the categories, the categories, the categories, the categories, the categories, the categories, the categories, the categories, the categories, the categories, the categories, the categories, the categories, the categories, the categories, the categories, the categories, the categories, the categories, the categories, the categories, the categories, the categories, the categories, the categories, the categories, the categories, the categories, the categories, the categories, the categories, the categories, the categories, the categories, the categories, the categories, the categories, the categories, the categories, the categories, the categories, the categories, the categories, the categories, the categories, the categories, the categories, the categories, the categories, the categories, the categories,

7:30 A wave function of a system could evolve. One was by the usual stringer equations and your operators squads. Now we know that if I were not having a can here, but if I were having another electron, no one would have any injection. They were perfectly happy with this linear position and we would know how it proved that the system was in a linear position. We also call it a slit experiment. You've got a linear superposition that's coherent as it is. There is a very clear indication that you can't suppress one of the terms, but the assumption about Moiré is that whenever we bring in an observer, this observer must suppress one term on the other. Now, one of the problems with this is what is an observer? Now, the idea is that he's plugging around for himself and many of his followers.

12:30 Now, what this means is, you can effectively have all the terminology, systems of complicated atoms, then you have a little bit of math to say, because it doesn't mean it's not alive or not.

20:00 What are the implications on the experimental apparatus, both in Europe and in the United States?

22:30 You can go here as many things as you want. This game is what I'm going to be playing, what I'm going to be doing. If you get sick, see, you're not, your mind has to be that the design is designed to drop down. Equally well designed to spin down. That's all it will see. It cannot see. I mean, the result of the experiment is either to spin up or to spin down. Yes, yes. Equally well, I mean, the result of the experiment would be to spin out of the board or spin into the board. That's sort of the general state. That's what the algorithm did. Thank you very much for your attention.

25:00 If I had to send you, by just turning to the Cern-Gerlach, you're just expecting this part. You're not telling, but the interpretation basis here is something that you can find by the interaction. Remember, the crucial point of a measurement is a permanent record. Now, I mean, permanent is in quotes, but in this case, you don't have to worry about the subtleties. Impermanent record is more exactly permanent. But the crucial thing is an interaction between the system and a permanent record.

27:30 Now, what sort of permanent record is going to the apparatus? So, unless you tell me when I switch to third row, I can't tell you more details. I can tell you what will happen if you give me more details. Well, I have a next question. Suppose you're right. How would you know? Well, the arguments are twofold. The first crucial fact about... Essentially, what I'm giving is that we know... We basically know that those facts really have to be there. For example, if rather than having to put a second Stern-Berlach with the star, now if in fact, if the reduction in the right order here, we do that, we don't see that, we get to assume a position. So we can't think about to get some of your interpretation of it because they're all pretty... The answer is that we know the superposition is there, plus the assumption that if the cat is alive, for example, we see the cat alive, or if the electron is dead, then from those two postulates, we certainly apply to once or never, and we've got no choice.

30:00 What you can try to do, if you can try to design a machine to propose it, what do you propose?

32:30 Well, we construct a quantum Turing machine, a quantum universal Turing machine working on quantum mechanics. And I suppose that memory elements can be superposed. And he says, let's just suppose that this is capable of appropriating memory in such a way that we can split it into pieces.

35:00 It maintains coherence in such a way that the superposition of these memory elements is indeed possible. It comes together again, but it retains observations in such a way that after the memory has come together again, Did you split? And it's capable of actually recording. So he proposes as the experiment, you make this quantum Turing machine as the Turing test so that it's about to be in its own right. You let go of this experiment. Okay, now number one.
