Challenges for extensions of the process matrix formalism to quantum field theory
Nikola Paunkovic, Marko Vojinovic
We discuss the issues with tentative generalisations of the process matrix formalism from finite-dimensional mechanical systems all the way to quantum field theory. We present a de…

Operational interpretation of the vacuum and process matrices for identical particles
Ricardo Faleiro, Nikola Paunkovic, Marko Vojinovic
This work overviews the single-particle two-way communication protocol recently introduced by del Santo and Dakić (dSD), and analyses it using the process matrix formalism. We give…

Causal orders, quantum circuits and spacetime: distinguishing between definite and superposed causal orders
Nikola Paunkovic, Marko Vojinovic
We study the notion of causal orders for the cases of (classical and quantum) circuits and spacetime events. We show that every circuit can be immersed into a classical spacetime,…
