Quantum entanglement allows particles to affect one another faster than the speed of light. So does this mean we could one day build a device to exploit this and enable superluminal communication? A popular trope in sci-fi for sure, but today let's look at the science. Presented by Prof David Kipping (Columbia). Special thanks to Prof. Ehud Altman (Berkeley), Prof Tim Byrnes (NYU) & Prof. Raquel Queiroz (Columbia) for fact checking our script. → Support our research program: → Get Stash here!
