Exceptional Points in Open Quantum Systems

We demonstrate how distinct quantum measurement bases evolve through interaction with the environment and can non-unitarily connect with each other at exceptional point degeneracies, leading to a non-Hermitian gate operation that does not require rotation.

Abstract

We demonstrate how distinct quantum measurement bases evolve through interaction with the environment and can non-unitarily connect with each other at exceptional point degeneracies, leading to a non-Hermitian gate operation that does not require rotation.
