Decoherence induced by dipole-dipole couplings between atomic species in rare-earth ion-doped YSiO
Charlotte Pignol, Antonio Ortu, Louis Nicolas +5
Rare-earth ion doped crystals are state-of-the-art platforms for processing quantum information, particularly thanks to their excellent optical and spin coherence properties at cry…
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…
Storage of photonic time-bin qubits for up to 20 ms in a rare-earth doped crystal
Antonio Ortu, Adrian Holzäpfel, Jean Etesse +1
Long-duration quantum memories for photonic qubits are essential components for achieving long-distance quantum networks and repeaters. The mapping of optical states onto coherent…
Spectroscopic study of hyperfine properties in Yb:YSiO
Alexey Tiranov, Antonio Ortu, Sacha Welinski +4
Rare-earth ion doped crystals are promising systems for quantum communication and quantum information processing. In particular, paramagnetic rare-earth centres can be utilized to…
Simultaneous coherence enhancement of optical and microwave transitions in solid-state electronic spins
Antonio Ortu, Alexey Tiranov, Sacha Welinski +5
Solid-state electronic spins are extensively studied in quantum information science, as their large magnetic moments offer fast operations for computing and communication, and high…
