Classical physics is still used in much of modern science and.
In 2007 I noticed a confusing post on Slashdot quoting from an article claiming that the no cloning theorem prevented entangled particles from being used for faster-than-light communication. I had never heard of any FTL implications of the no cloning theorem, so I responded to this post to see if a less-dumb scientist could explain this connection to me (incidentally, I’m still waiting.

Quantum entanglement is a physical phenomenon that occurs when pairs or groups of particles are generated, interact, or share spatial proximity in ways such that the quantum state of each particle cannot be described independently of the state of the other(s), even when the particles are separated by a large distance. Measurements of physical properties such as position, momentum, spin, and.
