Towards Device-Independent Quantum Key Distribution with Photonic Devices
Corentin Lanore, Xavier Valcarce, Jean Etesse +2
Quantum Key Distribution (QKD) protocols enable two distant parties to communicate with information-theoretically proven secrecy. However, these protocols are generally vulnerable…
Multipartite quantum correlated bright frequency combs
Adrien Bensemhoun, Silvia Cassina, Carlos Gonzalez-Arciniegas +12
This experimental work demonstrates multipartite quantum correlation in bright frequency combs out of a microresonator integrated on silicon nitride operating above its oscillation…
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…
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…
A multiplexed synthesizer for non-Gaussian photonic quantum state generation
M. F. Melalkia, J. Huynh, S. Tanzilli +2
Disposing of simple and efficient sources for photonic states with non-classical photon statistics is of paramount importance for implementing quantum computation and communication…
Plug-&-play generation of non-Gaussian states of light at a telecom wavelength
Mohamed Faouzi Melalkia, Tecla Gabbrielli, Antoine Petitjean +5
This work marks an important progress towards practical quantum optical technologies in the continuous variable regime, as it shows the feasibility of experiments where non-Gaussia…
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…
Optical storage for 0.53 seconds in a solid-state atomic frequency comb memory using dynamical decoupling
Adrian Holzäpfel, Jean Etesse, Krzysztof T. Kaczmarek +3
Quantum memories with long storage times are key elements in long-distance quantum networks. The atomic frequency comb (AFC) memory in particular has shown great promise to fulfill…
Characterization of the hyperfine interaction of the excited D state of Eu:YSiO
Emmanuel Zambrini Cruzeiro, Jean Etesse, Alexey Tiranov +5
We characterize the Europium (Eu) hyperfine interaction of the excited state (D) and determine its effective spin Hamiltonian parameters for the Zeeman and quadrupol…
Multi-mode and long-lived quantum correlations between photons and spins in a crystal
Cyril Laplane, Pierre Jobez, Jean Etesse +2
The realization of quantum networks and quantum repeaters remains an outstanding challenge in quantum communication. These rely on entanglement of remote matter systems, which in t…
Multiplexed on-demand storage of polarization qubits in a crystal
Cyril Laplane, Pierre Jobez, Jean Etesse +3
A long-lived and multimode quantum memory is a key component needed for the development of quantum communication. Here we present temporally multiplexed storage of 5 photonic polar…
Generation of squeezed Schrödinger cat states with an operation allowing iterative growth
Jean Etesse, Martin Bouillard, Bhaskar Kanseri +1
We present what is to our knowledge the first implementation of a Schrödinger cat states "breeding" operation, which allows an iterative growth of these states. We thus report the…

Jean Etesse, Rémi Blandino, Bhaskar Kanseri +1
We demonstrate that different kind of mesoscopic quantum states of light can be efficiently generated from a simple iterative scheme using homodyne heralding. These states exhibit…
