Chiral Bell-state transfer via dissipative Liouvillian dynamics

Shishir Khandelwal, Weijian Chen, Kater W. Murch, Géraldine Haack

Chiral state transfer along closed loops in the vicinity of an exceptional point is one of the many counter-intuitive observations in non-Hermitian physics. The application of this property beyond proof-of-principle, specifically in quantum physics, is an open question. In this work, we demonstrate chiral state conversion between singlet and triplet Bell states through fully-quantum Liouvillian dynamics. Crucially, we demonstrate that this property can be used for the chiral production of Bell states from separable states with a high fidelity and for a large range of parameters. Additionally, we show that the removal of quantum jumps from the dynamics through postselection can result in near-perfect Bell states from initially separable states. Our work paves the way to a novel type of quantum control and a potential application of non-Hermitian physics in quantum information processing.
