Quantum Networks with Deterministic Spin-Photon Interfaces
J. Borregaard, A. S. Sørensen, P. Lodahl
We consider how recent experimental progress on deterministic solid state spin-photon interfaces enable the construction of a number of key elements of quantum networks. After revi…
Enhancing quantum transduction via long-range waveguide mediated interactions between quantum emitters
Vincent E. Elfving, Sumanta Das, Anders S. Sørensen
Efficient transduction of electromagnetic signals between different frequency scales is an essential ingredient for modern communication technologies as well as for the emergent fi…
High dimensional measurement device independent quantum key distribution on two dimensional subspaces
Luca Dellantonio, Anders S. Sørensen, Davide Bacco
Quantum key distribution (QKD) provides ultimate cryptographic security based on the laws of quantum mechanics. For point-to-point QKD protocols, the security of the generated key…
Suppressing phonon decoherence of high performance single-photon sources in nanophotonic waveguides
Chris L. Dreeßen, Claudéric Oullet-Plamondon, Petru Tighineanu +4
The fundamental process limiting the coherence of quantum-dot based single-photon sources is the interaction with phonons. We study the effect of phonon decoherence on the indistin…
Strongly correlated photon transport in waveguide QED with weakly coupled emitters
Sahand Mahmoodian, Mantas Čepulkovskis, Sumanta Das +3
We show that strongly correlated photon transport can be observed in waveguides containing optically dense ensembles of emitters. Remarkably, this occurs even for weak coupling eff…
Long-lived non-classical correlations for scalable quantum repeaters at room temperature
Michael Zugenmaier, Karsten B. Dideriksen, Anders S. Sørensen +2
Heralded single-photon sources with on-demand readout are promising candidates for quantum repeaters enabling long-distance quantum communication. The need for scalability of such…
