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…
Hybrid Single-Ion Atomic-Ensemble Node for High-Rate Remote Entanglement Generation
Benedikt Tissot, Soubhadra Maiti, Emil R. Hellebek +1
Different quantum systems possess different favorable qualities. On the one hand, ensemble-based quantum memories are suited for fast multiplexed long-range entanglement generation…
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…
