    Summary

    Photon anti-bunching, a quantum light signature, cannot be achieved by interfering weak lasers. This study reveals that such schemes can lead to super-Poissonian statistics, not the desired sub-Poissonian photon counts.

    Area of Science:

    • Quantum optics
    • Quantum information science

    Background:

    • Photon anti-bunching is a key indicator of quantum light, linked to sub-Poissonian photon statistics.
    • Recent studies suggested achieving photon anti-bunching through laser interference and photon counting.

    Purpose of the Study:

    • To theoretically analyze the limitations of manipulating conditional photon statistics using weak laser interference.
    • To determine if photon anti-bunching is achievable in such experimental setups.

    Main Methods:

    • Theoretical analysis of conditional photon statistics.
    • Investigation of higher-order photon number expansions in coherent states.

    Main Results:

    • Conditional photon number statistics can become super-Poissonian.
    • Photon anti-bunching (sub-Poissonian statistics) cannot be obtained via this method.
    • Ignoring higher-order expansions can lead to incorrect conclusions.

    Conclusions:

    • The interference of weak lasers does not yield photon anti-bunching.
    • Accurate theoretical treatment, including higher-order terms, is crucial for understanding photon statistics.
