Quantum Mechanics (Chapter 6): Quantum Entanglement - The Weirdness Of Quantum Mechanics. --- Please SUBSCRIBE to Science & Reason: • http://www.youtube.com/Best0fSciencehttp://www.youtube.com/ScienceTVhttp://www.youtube.com/FFreeThinker --- Quantum entanglement, also called the quantum non-local connection, is a property of a quantum mechanical state of a system of two or more objects in which the quantum states of the constituting objects are linked together so that one object can no longer be adequately described without full mention of its counterpart—even if the individual objects are spatially separated in a spacelike manner. The property of entanglement was understood in the early days of quantum theory, although not by that name. Quantum entanglement is at the heart of the EPR paradox developed by Albert Einstein, Boris Podolsky, and Nathan Rosen in 1935. This interconnection leads to non-classical correlations between observable physical properties of remote systems, often referred to as nonlocal correlations. Quantum mechanics holds that observables, for example spin, are indeterminate until some physical intervention is made to measure an observable of the object in question. In the singlet state of two spin, it is equally likely that any given particle will be observed to be spin-up or spin-down. Measuring any number of particles will result in an unpredictable series of measurements that will tend to a 50% probability of the spin being up or down. However, the results are quite different if this experiment is done with entangled particles. For example, when two members of an entangled pair are measured, their spin measurement results will be correlated. Two (out of infinitely many) possibilities are that the spins will be found to always have opposite spins (in the spin-anti-correlated case), or that they will always have the same spin (in the spin-correlated case). Measuring one member of the pair therefore tells you what spin the other member would have if it were also measured. The distance between the two particles is irrelevant. • http://en.wikipedia.org/wiki/Quantum_entanglement --- The Cassiopeia Project - making science simple!

Never miss an episode. Subscribe here: http://goo.gl/B2RPd Science Rap Songs here: http://goo.gl/fCSXF Coma Niddy explains Quantum Entanglement and how it can improve the way we use technology. Share your science questions in the comments and they might be the next episode! Transcript: When two people get married they become entangled. Any action that affects one person will affect the other. When one person's happy, the other person's happy. If one person is sad, the other person is sad. Entanglement also happens in sports. If your team wins, then you win. If you team loses, you lose too. It doesn't even matter if you were on the field or on the bench. Your team affects you. Entanglement also happens with particles. This is known as Quantum Entanglement. Scientists can entangle two particles and whatever they do to one particle will affect the other. And this effect happens instantaneously. And it doesn't even matter where the particles are. You can have one particle over here, one particle over there. I affect this one, it changes and the other changes instantaneously. They can be right next to each other or they can be on opposite sides of the universe. And no matter what we do to one particle it will affect the other one instantaneously. Now the crazy part about this is that scientists, although they know how to entangle the particles, they have no idea as to how entanglement works. It's so strange so spooky -even stranger than marriage... Albert Einstein himself referred to quantum entanglement as "Spooky Action at a Distance" So why is quantum entanglement important to us? Well everybody uses computers and electronic devices all the time. And it takes time for the information that's being sent from one computer to reach the other. Well if we start using quantum computers and quantum internet, we can instantaneously send information from one computer to the other. And it doesn't matter where those computers are. That will drastically change the way we use computers. Imagine going on YouTube and being able to download a video without it buffering while you're trying to show it to your friends. So quantum computers and quantum internet might be the next big step in our technology. The last time I checked technology is pretty awesome. And that's why Quantum Entanglement matters. So let's keep the awesome technology coming and let's keep those particles married.

Does quantum entanglement make faster-than-light communication possible? What is NOT random? http://bit.ly/NOTrandoVe First, I know this video is not easy to understand. Thank you for taking the time to attempt to understand it. I've been working on this for over six months over which time my understanding has improved. Quantum entanglement and spooky action at a distance are still debated by professors of quantum physics (I know because I discussed this topic with two of them). Does hidden information (called hidden variables by physicists) exist? If it does, the experiment violating Bell inequalities indicates that hidden variables must update faster than light - they would be considered 'non-local'. On the other hand if you don't consider the spins before you make the measurement then you could simply say hidden variables don't exist and whenever you measure spins in the same direction you always get opposite results, which makes sense since angular momentum must be conserved in the universe. Everyone agrees that quantum entanglement does not allow information to be transmitted faster that light. There is no action either detector operator could take to signal the other one - regardless of the choice of measurement direction, the measured spins are random with 50/50 probability of up/down.
