TL;DR
This paper demonstrates a non-classical interference effect between independent photon sources, showing that the probability of simultaneous detections approaches zero due to destructive interference, using pulse-gated single photons and weak laser pulses.
Contribution
It experimentally shows non-classical interference between independent sources with pulse gating, advancing understanding of quantum interference phenomena.
Findings
Probability of simultaneous detections approaches zero
Destructive interference observed between independent sources
Effective use of pulse gating in experiments
Abstract
When a one-photon state is mixed with a (separate) weak coherent state at a beamsplitter the probability for detecting one photon in each beamsplitter output approaches zero due to destructive interference. We demonstrate this non-classical interference effect using pulse-gated single photons and weak mode-locked laser pulses.
