• Abstract: We sketch applications of the so-called J-equation to quantum information theory concerning fundamental properties of the von Neumann entropy. The J-equation has recently be proposed as a sort of progenitor of the various versions of the Jarzynski equation. It has been derived within a general framework of sequential measurements that is slightly generalised here.

  We classify qubit QCAs on lattices $mathbb Zs$ with von Neumann neighbourhood scheme, in terms of feasibility as finite depth quantum circuits. We show the most general structure of such quantum circuit and use its characterisation to simulate a few steps of evolution and evaluate the rate of entanglement production between one cell and its surroundings.

We also show that DNTs emerge naturally from a particular instance of a joint measurability problem, remarking its relevance in general operator theory.
