Single and Double-click High-Rate Entanglement Generation Between Distant Ions Using Multiplexed Atomic Ensembles

Benedikt Tissot, Soubhadra Maiti, Emil R. Hellebek +1

In an accompanying paper [arxiv:2511.04488], we introduced an approach to interface trapped-ion quantum processors with ensemble-based quantum memories by matching a spontaneous pa…

Entanglement Enhanced Sensing with Qubits affected by non-Markovian Dephasing

Noah Kaufmann, Kasper H. Nielsen, Eva M. González-Ruiz +1

Entanglement has been proposed as a means to improve the sensitivity of sensing weak signals. While the degree of this quantum advantage is well understood in noiseless settings, t…

Steady-State Multiparticle Entanglement via Dissipative Engineering in Waveguide QED

Joan Alba, Jacob Thornfeldt Hansen, Jean-Baptiste S. Béguin +1

We propose a simple scheme for the dissipative generation of entangled states of multiple emitters coupled to a waveguide. Our approach exploits collective interactions arising fro…

Quantum Strategies to Overcome Classical Multiplexing Limits

Tzula B. Propp, Jeroen Grimbergen, Emil R. Hellebek +5

Near-term quantum networks face a bottleneck due to low quantum communication rates. This degrades performance both by lowering operating speeds and increasing qubit storage time i…

The impact of multimode sources on DLCZ type quantum repeaters

Emil R. Hellebek, Anders S. Sørensen

Long distance entanglement generation at a high rate is a major quantum technological goal yet to be fully realized, with the promise of many interesting applications, such as secu…
