- Abstract: 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.
