With The Physics Nobel Prize 2022, a lot about Quantum Entanglement in circulation. Here's a nice video where Prof Mike Merrifield (University of Nottingham) explains what Einstein called "Spooky Action at a Distance".
Recent experiments have spotted this effect in objects small enough to see. (visible to the naked eye) and also at great distances (Earth to a Satellite), It would be possible that in future Quantum keys could be exchanged without the fear of eavesdropping, leading to hack proof communications and hack proof internet.
