Disclaimer: I am completely new to strawberry fields, and also not very well-versed in thinking in terms of CV, so sorry if this is an obvious question!
What I’m trying to simulate is basic Hong-Ou-Mandel interference, but to look at this when there is a slight time-delay between the two incident photons (so still some temporal overlap, but the photons are no longer completely indistinguishable). I feel quite happy with the HOM example given here Threshold detector probabilities of Gaussian states — Strawberry Fields but am struggling with trying to include some distinguishability. Is this possible?
Hey @DistractedHedgehog welcome to the Forum!
Sorry for our late response. We’ll be back soon with an answer!
Yes it is possible but not with Strawberry Fields. You will need to use the internal_modes branch of The Walrus.
You can install it by running
pip install git+https://github.com/XanaduAI/thewalrus.git@internal_modes
My colleague David has been very kind to share this notebook which shows how to do what you need.

Please let me know if this helps!
Thanks very much for your help, and also to David for the fantastic notebook – this is exactly what I was trying to do! The internal_modes branch seems really powerful with regards to all the realistic experimental imperfections it can incorporate.
I’m glad this worked for you @DistractedHedgehog ! I’m happy to help. And I’ve forwarded your Thank You to David too!
