Entanglement in prepare-and-measure scenarios without receiver inputs
Elna Svegborn, Armin Tavakoli
The most elementary prepare-and-measure scenarios have no independent measurement inputs. No inputs mean that quantum advantages require two indispensable ingredients: shared entan…

Framework for (non-)adiabatic chiral state conversion: from non-Hermitian Hamiltonians to Liouvillians
Elna Svegborn, Shishir Khandelwal
Adiabatic chiral state conversion (CSC) is one of the many counterintuitive effects associated with non-Hermitian physics. In quantum systems, numerous works have demonstrated this…

Quantum inputs in the prepare-and-measure scenario and stochastic teleportation
Elna Svegborn, Jef Pauwels, Armin Tavakoli
We investigate prepare-and-measure scenarios in which a sender and a receiver use entanglement to send quantum information over a channel with limited capacity. We formalise this f…
