Podcasts about bell's theorem

The question, whether a local, realistic theory can be a valid description of nature led to Bell's formulation of a clear cut experimental test. In spite of the many measurements performed and the numerous violation of Bell's inequality, all these tests relied on assumptions opening loopholes for local realistic theories. We present experiments which attempted to close as many as possible loopholes during the recent years, and what still might be left to do. In the experiment, as Bell's inequality limits preshared knowledge about possible measurement results, it can be used on the one hand to now confirm random numbers deduced from measurement results or the security of the devices used for quantum key distribution. On the other hand we can use the techniques developed for this experiment as the basic link for future quantum networks distributing entanglement efficiently over larger distances.

Athena & Raafae join one of the nerds to have a chat about one of the most mysterious areas in physics... quantum mechanics!This chat was really an overview of the major ideas in the field. Quanta and photons. Wave particle duality. Matter as a wave. The Uncertainty Principle. Schrodinger's Equation & the Wave function. The measurement problem & the Copenhagen Interpretation. Entanglement & Bell's Theorem. Hidden Variables and Many Worlds.It is near impossible for us to explore all of the mysteries of Quantum Mechanics in one sitting! But if you would like us to do more in-depth chats about more specific topics, let us know!If you would like to see what the nerds look like, check us out on YouTube at:https://www.youtube.com/c/BetweenTwoNerdsAnd for more information about Curiosity Lab, how we make kids fall in love with science, check out:https://www.curiositylab.ae

A recent discovery in quantum mechanics seems to confirm a very unsettling fact about quantum entanglement that will affect everything we have ever known. This is what Einstein called "spooky action at a distance". In 1964, Irish physicist John Bell developed "Bell's Theorem" also known as Superdeterminism which says freewill and choice are only illusions. Bell theorized everything is predetermined and humans only believe they have freewill. In this episode we will discuss the shocking implications if this is indeed true and what it means to life and the world as we know it. This knowledge transcends this world and our known dimensions. Join us for new explosive, shocking information that will make you reconsider everything you "know".

Huw Price (Cambridge) gives a talk at the MCMP Colloquium titled "Retrocausality - What Would it Take?". Abstract: Some writers argue that retrocausality offers an attractive loophole in Bell's Theorem, allowing an explanation of EPR-Bell correlations without "spooky action-at-a-distance." This idea originated more than a decade before Bell's famous result, when de Broglie's student, Olivier Costa de Beauregard, first proposed that retrocausality plays a role in EPR contexts. The proposal is difficult to assess, because there has been little work on the general question of what a world with retrocausality would "look like" - what kinds of considerations, if any, would properly lead to the conclusion that we do live in such a world. In this talk I discuss these general issues, with the aim of bringing the more specific question as to whether quantum theory implies retrocausality into sharper focus than has hitherto been possible.

The history of physics as a natural science is filled with examples of when an experiment will demonstrate something or another, but what is often forgotten is the fact that the experiment had to be thought up in the first place by someone who was aware of more than one plausible value for a property of the universe, and realized that there was a way to word a question in such a way that the universe could understand. Such a property was debated during the quantum revolution, and involved Einstein, Polodsky, Rosen, and Schrödinger. The question was 'do particles which are entangled "know" the state of one another from far away, or do they have a sort of "DNA" which infuses them with their properties?' The question was thought for a while to be purely philosophical one until John Stewart Bell found the right way to word a question, and proved it in a laboratory of thought. It was demonstrated to be valid in a laboratory of the universe. So how do particles speak to each other from far away? What do we mean when we say we observe something? And how is a pair of gloves like and unlike a pair of walkie talkies? --- This episode is sponsored by · Anchor: The easiest way to make a podcast. https://anchor.fm/app Support this podcast: https://anchor.fm/breakingmathpodcast/support
