Scientists just pulled off a wild quantum trick: they made quantum entanglement reversible using a so-called 'entanglement battery.' Think of it like a power bank, but for the weird connections between quantum particles. This means entanglement can now flow in and out without being lost—just like energy in a perfect engine! It’s a huge deal for future quantum computers and secure networks. The catch? The battery’s still just a theory, but real-life versions could be coming soon. Mind = blown. #Science #QuantumPhysics #Entanglement
