Efficient and reversible optical-to-spin conversion for solid-state quantum memories
Jingjing Chen, Mikael Afzelius
Long-duration and efficient quantum memories for photons are key components of quantum repeater and network applications. To achieve long duration storage in atomic systems, a shor…
Towards the device-independent certification of a quantum memory
Pavel Sekatski, Jean-Daniel Bancal, Marie Ioannou +2
Quantum memories represent one of the main ingredients of future quantum communication networks. Their certification is therefore a key challenge. Here we develop efficient certifi…
Proposal for spin squeezing in rare-earth ion-doped crystals with a four-color scheme
Tamás Kriváchy, Krzysztof T. Kaczmarek, Mikael Afzelius +2
Achieving spin squeezing within solid-state devices is a long standing research goal, due to the promise of their particularities, for instance their long coherence times, the poss…
Remote distribution of non-classical correlations over 1250 modes between a telecom photon and a Yb:YSiO crystal
Moritz Businger, Louis Nicolas, Théo Sanchez Mejia +3
Quantum repeaters based on heralded entanglement require quantum nodes that are able to generate multimode quantum correlations between memories and telecommunication photons. The…
A readout-integrated time-bin qutrit analyzer for echo-based quantum memories
Adrian Holzäpfel, Antonio Ortu, Mikael Afzelius
We present a method to project time-bin qutrits stored in an echo-based quantum memory using several successive partial readouts of the memory. We demonstrate how this scheme can b…
Multimode capacity of atomic-frequency comb quantum memories
Antonio Ortu, Jelena V. Rakonjac, Adrian Holzäpfel +5
Ensemble-based quantum memories are key to developing multiplexed quantum repeaters, able to overcome the intrinsic rate limitation imposed by finite communication times over long…
