Memory-built-in quantum teleportation with photonic and atomic qubits

Understand

The combination of quantum teleportation and quantum memory of photonic qubits is essential for future implementations of large-scale quantum communication and measurement-based quantum computation.

• Both steps have been achieved separately in many proof-of-principle experiments, but the demonstration of memory-built-in teleportation of photonic qubits remains an experimental challenge.
• Here, we demonstrate teleportation between photonic (flying) and atomic (stationary) qubits.
• In our experiment, an unknown polarization state of a single photon is teleported over 7 m onto a remote atomic qubit that also serves as a quantum memory.
