@CarlosSMW @OpticsOlomouc @QuantumHedgehog @IvoStraka @PhysRevLett @PhotonicsMeetup This issue is discussed in https://t.co/I4dna60An7 @stenssok. Instead, we evaluate g2(0) and other quantum state parameters from retrieved photon statistics. The accuracy of the statistics retrieval affects the accuracy of the parameters being assessed. (3/3)

@CarlosSMW @OpticsOlomouc @QuantumHedgehog @IvoStraka @PhysRevLett @PhotonicsMeetup For single-photon emitters with a low detection rate, everything is nice, and the value of the HBT measurement agrees well with g2(0) parameter. Unfortunately, for states with negligible multiphoton content, the HBT fails to produce the correct value of g2(0). (2/3)

[Josef Hloušek @HlousekScience]

@CarlosSMW @OpticsOlomouc @QuantumHedgehog @IvoStraka @PhysRevLett @PhotonicsMeetup g2(0) is defined using the first and second moments of photon statistics - strictly speaking, it cannot be directly measured. HBT actually gives the anticorrelation parameter, not the g2. (1/3)
