Summary
Quantum cryptography makes secure communication possible today, but with existing technology is limited to less than 100 km. A quantum repeater could overcome this limitation in principle but has not been built yet. We follow two different experimental approaches toward a photon-photon quantum gate, which is an essential component needed for a quantum repeater.
