Single-photon generation

Single photons can be used as information carriers in, e.g., quantum key distribution schemes or as qubits in photonic quantum computers.

You can generate single photons by reducing the output power of your laser to the point where it emits a single photon at a time. Due to the random nature of this approach, the laser emits photons spontaneously and unpredictably, which has advantages and drawbacks.
