On the accuracy of twirled approximations in repeater chains
Bethany Davies, Guus Avis, Stephanie Wehner
In the performance analysis of quantum networks, it is common to approximate bipartite entangled states as either being Bell-diagonal or Werner states. We refer to these as twirled…

Entanglement buffering with multiple quantum memories
Álvaro G. Iñesta, Bethany Davies, Sounak Kar +1
Entanglement buffers are systems that maintain high-quality entanglement, ensuring it is readily available for consumption when needed. In this work, we study the performance of a…

Entanglement buffering with two quantum memories
Bethany Davies, Álvaro G. Iñesta, Stephanie Wehner
Quantum networks crucially rely on the availability of high-quality entangled pairs of qubits, known as entangled links, distributed across distant nodes. Maintaining the quality o…
