Quantum entanglement is the key to quantum computing, cryptography, and numerous other real-world applications of quantum mechanics. It is also one of the strangest phenomena in the Universe, overcoming barriers of space and time and knitting the entire cosmos into an integrated whole. Scientists have long thought that entanglement between two particles was a rare and fleeting phenomenon, so delicate that exposure of the particles to their surroundings would quickly destroy this linkage. Now mathematicians at Case Western University have shown that entanglement between parts of large systems is the norm, rather than being a rare and short-lived relationship.
