Counterfactual restrictions and Bell’s theorem

Jonte R Hance • Journal of Physics Communications (2024)

We show that the ability to consider counterfactual situations is a necessary assumption of Bell’s theorem, and that, to allow Bell inequality violations while maintaining all other assumptions, we just require certain measurement choices b...

Group Geometrical Axioms for Magic States of Quantum Computing

Michel Planat, Raymond Aschheim, Marcelo M. Amaral, Klee Irwin • Mathematics (2019)

Let H be a nontrivial subgroup of index d of a free group G and N be the normal closure of H in G. The coset organization in a subgroup H of G provides a group P of permutation gates whose common eigenstates are either stabilizer states of ...

The rank of contextuality

Karol Horodecki, Jingfang Zhou, Maciej Stankiewicz, Roberto Salazar et al. • New Journal of Physics (2023)

Quantum contextuality is one of the most recognized resources in quantum communication and computing scenarios. We provide a new quantifier of this resource, the rank of contextuality (RC). We define RC as the minimum number of non-contextu...
