We also introduce a new graphical language for optical protocols featuring delays, routers, switches and photonic machine guns

Our work on photonic MBQC is out on the arXiv! https://t.co/ieYaOLIguu

We study errors induced by photonic fusion measurements and give flow structure to correct them.

It is aimed more at a physics audience.

New paper out on arXiv! We give a "parameter-shift" rule for linear optical circuits. https://t.co/hNC4Ss3e5i

Looking forward to it. Yes this is missing the optics.

We are out on the same day! Nice, this paper was much awaited.

It features some very nice dilation theory with a 1950 result by Halmos

And probably some reductions are not beta reductions like in Robin's blog post

Montague's treatment of semantics is purely _functional_, while Peirce's existential graphs are _topological_, only connectivity matters.

You have to explicitly give the beta-reduction

It also has a very nice graphical language with sheets https://t.co/Fj05rl14Pa

What we were thinking is using the category of pointed profunctors Prof*(C) over a monoidal category C. This category is compact closed, and you can encode any higher-order operator (comb/bubble etc.) as a morphism in there.

Can this box copying happen topologically?

With Mario Roman we had some ideas for doing this using profunctors.
