✨ Transferring Quantum States
Quantum teleportation: Transfer unknown quantum state |ψ⟩ from Alice to Bob using shared entanglement + classical communication. Not faster-than-light, no violation of relativity—requires 2 classical bits sent at light speed. Original state destroyed (no-cloning theorem preserved). First demonstrated 1997 (photons), now achieved with atoms, ions, solid-state qubits.
🎯 Key Misconceptions
❌ Not sci-fi teleportation: Information transfer, not matter transport
❌ Not faster than light: Classical communication required—limited by c
✓ Quantum state transfer: Unknown state recreated perfectly at distant location
✓ Original destroyed: No-cloning theorem—can't duplicate quantum states
