Efficient Teleportation Between Remote Single-Atom Quantum Memories
Efficient Teleportation Between Remote Single-Atom Quantum Memories
We demonstrate teleportation of quantum bits between two single atoms in distant laboratories. Using a time-resolved photonic Bell-state measurement, we achieve a teleportation fidelity of (88.0+/-1.5)%, largely determined by our entanglement fidelity. The low photon collection efficiency in free space is overcome by trapping each atom in an optical cavity. …
