Networks of quantum reference frames and the nature of conserved quantities
Daniel Collins, Carolina Moreira Ferrera, Ismael L. Paiva +1
We show that networks of quantum frames of reference, in which one frame may be used to produce multiple other frames that in their turn prepare systems which may interact with one…

Conservation Laws For Every Quantum Measurement Outcome
Daniel Collins, Sandu Popescu
In the paradigmatic example of quantum measurements, whenever one measures a system which starts in a superposition of two states of a conserved quantity, it jumps to one of the tw…
