Making of a zero-area single photon pulse

We just realized the first single-photon version of a zero-area ultrashort pulse.

Hybrid entanglement of light

We produced entanglement between differently-encoded photonic qubits. A single-photon-based qubit state on one side and a coherent-state-based one on the other. The situation closely resembles the quantum-classical hybrid entanglement of the atom-cat system in the Schroedinger’s cat paradox. Nature Photonics made a cover out of the story (and of our image).
