History of Quantum Entanglement
Quantum entanglement was first described in 1935 and has led to today’s quantum revolution.
Abstract
Quantum entanglement, first described by Einstein and colleagues in 1935, puzzled scientists for decades. Schrödinger named it, Bell proved it, and Aspect confirmed it experimentally, leading to today’s quantum revolution.
Have you ever heard of two particles being connected across space, no matter how far apart they are? This strange phenomenon is known as quantum entanglement, and it’s one of the most perplexing concepts in all of science. But who conceived this mind-bending concept, and who has helped us understand it better over the years?
The Beginning: Einstein’s “Spooky Action”
The story starts in 1935 with Albert Einstein and two other physicists, Boris Podolsky and Nathan Rosen. They wrote a famous paper that described an odd phenomenon in quantum mechanics — the science of tiny particles. They demonstrated that, according to quantum theory, two particles can be connected in a way that measuring one particle instantly affects the other, even if they are on opposite sides of the universe.
Einstein didn’t like this idea at all. He called it “spooky action at a distance” and thought it proved that quantum mechanics was…
