Bring coherent main back

source is operated in two-mode squeezing mode and one arm is used to herald single photons in the corresponding timebin ending in the spatial mode after the demux. HOM_4fold contains the corresponding delays and the function to obtain 4 fold coincidences on channel 1 and 2 (counnting stars at 0) of the Quix chip. the Quix chip is programmed to interfere channel 1 with channel n and direct it to output 1 and 2 of the Quix output. the first data raw is performed around T0 +- 4degC of the best last known temperatures where interference was observed. The temperatures are changed in steps of 0.4 degC and stabilized untilthe read temperature from the PLSUs ist not chaning more than 0.1degC from its last value in the time window of 60s. The second measurement goes from T0+3 to T0+8 degC as HOM was not observed for most channels. THe lastest measurement show more channels with HOM but it seems that 0.4degC is a too large temperature step to observe HOM on every channel. pulsematch measurement hom.ipynb is the used script to measure the data
