Summary

A deterministic source combined fast excitation with system efficiency to deliver more than 500 megahertz of in-fiber single-photon flux.

The photonic source reports more than 500 million single photons per second delivered in fiber while producing over 100 picowatts of optical power. That level is high enough to measure with an off-the-shelf power meter, offering a direct route to estimating the source's fiber efficiency. The paper's contribution is the simultaneous combination of excitation rate and system efficiency in one deterministic source; the abstract does not establish performance inside a complete quantum network or computing system.

Why it matters

A deterministic source combined fast excitation with system efficiency to deliver more than 500 megahertz of in-fiber single-photon flux.

Limits and context

  • The paper's contribution is the simultaneous combination of excitation rate and system efficiency in one deterministic source; the abstract does not establish performance inside a complete quantum network or computing system.
