I Measuring Second-Order Correlation Function with Start and Stop Signal

Click For Summary
Measuring the second-order correlation function with a device limited to start and stop measurements, which can only record five stops, presents challenges in capturing independent events. The discussion highlights the need to measure coincidences, independent events in each channel, total measurement time, and the coincidence window. However, clarity is lacking on how to effectively measure these independent events with the given constraints. Participants are encouraged to provide specific references or context regarding the device in question for better understanding. The conversation emphasizes the importance of detailed information to facilitate accurate measurement techniques.

How is it possible to measure the second-order correlation function with a device that can only perform start and stop measurements, and for each measurement, it can only record 5 stops? I understand that experimentally it is necessary to measure the coincidences, the independent events in each channel, the total measurement time, and the coincidence window. However, it is still not clear to me how to measure these independent events using only starts and stops. The device has 2 reception channels.

Perhaps you could share with us a reference for what you are asking about. As written, I cannot discern the context - and I doubt others will either.

What device? A specific reference would be helpful.
 
For the quantum state ##|l,m\rangle= |2,0\rangle## the z-component of angular momentum is zero and ##|L^2|=6 \hbar^2##. According to uncertainty it is impossible to determine the values of ##L_x, L_y, L_z## simultaneously. However, we know that ##L_x## and ## L_y##, like ##L_z##, get the values ##(-2,-1,0,1,2) \hbar##. In other words, for the state ##|2,0\rangle## we have ##\vec{L}=(L_x, L_y,0)## with ##L_x## and ## L_y## one of the values ##(-2,-1,0,1,2) \hbar##. But none of these...
