NPA Hierarchy for Quantum Isomorphism and Homomorphism Indistinguishability

Prem Nigam Kar, David E. Roberson, Tim Seppelt +1

Mančinska and Roberson [FOCS'20] showed that two graphs are quantum isomorphic if and only if they admit the same number of homomorphisms from any planar graph. Atserias et al. [JC…

Transitive Nonlocal Games

Prem Nigam Kar, Jitendra Prakash, David E Roberson

We study a class of nonlocal games, called transitive games, for which the set of perfect strategies forms a semigroup. We establish several interesting correspondences of bisynchr…
