Robust self-testing for nonlocal games with robust game algebras
Yuming Zhao
We give an operator-algebraic formulation of robust self-testing in terms of states on C*-algebras. We show that a quantum correlation p is a robust self-test only if among all (ab…

Postselection technique for optical Quantum Key Distribution with improved de Finetti reductions
Shlok Nahar, Devashish Tupkary, Yuming Zhao +2
The postselection technique is an important proof technique for proving the security of quantum key distribution protocols against coherent attacks. In this work, we go through mul…
