Scientists have created a tiny light catcher that works like a mailbox: a photon flies in, gets delayed, and flies back out with almost no loss. Efficiency up to 80% for laser pulses and simultaneous storage of 20 light patterns bring quantum internet closer.
🎯 A crystal with europium ions can store a light pulse for longer than a millisecond—by quantum standards, that's an eternity, during which light would circle the Earth more than seven times.
