Quantum nonlocality - Lecture 9
'Quantum nonlocality' lecture given by Martin Plávala at Leibniz University Hannover.
Lecture 9
Quantum nonlocality, in some of its many forms, is a peculiar phenomenon that by definition lacks an explanation in terms of classical physics or classical probability theory. Moreover quantum nonlocality often appears as a necessary component in obtaining quantum advantage over classical computers or classical cryptographic protocols. For these reasons quantum nonlocality has been heavily researched in the recent years, yet many theoretical questions remain open.
These lectures will introduce quantum nonlocality in the form of entanglement, violations of Bell inequalities, and correlations arisi...

So there must be 8 previous shows 😮
Take it with a shovel of salt?! Not a pinch no? I honestly believe I have been connected to this process throughout my 32 years of life. Many times I have “hallucinated” what I believe to be physically happening there and then. In my sleep, my “dreams” are rarely “me” im usually “someone else”
The description is somewhat puzzling: surely you're introducing entanglement in the [specific, physical] form of quantum nonlocality rather than the other way around? And entanglement does have a perfectly good explanation in terms of non-classical probability of course - as well as (potentially) useful applications that don't involve physical nonlocality (e.g. arXiv:2003.09961).
It would be nice if lecture notes were provided!
overheard 3 students at Starbucks discussing this last week. and now its on my youtube feed...so weird. :)
Does the course have website?
Unfortunately not, the course is available via these videos.
At 2.02 you plot "particle number" on the left. Could you please duscuss / define this term. As it appears to be a [computed Value] divided by N. Is N the number of quantum particles in the system at time zero. What is the [computed value] ? E.g. is it a computer solution of an observable quantity. Is it a statistical average of many simulations.

What a nerd - he’s magnificent!
Interesting. But what do logs have to do with the theory. Why not whole trees?
logs are here natural logs, usually abbreviated ln . :-)
