Accessing which-path information in the absorption and emission of light by a quantum dot in a Ramsey sequence
I. Maillette de Buy Wenniger, M. Maffei, S. C. Wein +8
We quantify which-path information in the absorption and emission of light by a quantum dot along a Ramsey-like sequence. The quantum dot is excited by two successive classical $Ï…
Microscopic dynamics and relaxation processes in liquid Hydrogen Fluoride
R. Angelini, P. Giura, D. Fioretto +3
Inelastic x-ray scattering and Brillouin light scattering measurements of the dynamic structure factor of liquid hydrogen fluoride have been performed in the temperature range$ T=2…
High-rate entanglement between a semiconductor spin and indistinguishable photons
N. Coste, D. Fioretto, N. Belabas +15
Photonic graph states, quantum light states where multiple photons are mutually entangled, are key resources for optical quantum technologies. They are notably at the core of error…
Indistinguishable photons from a trapped-ion quantum network node
M. Meraner, A. Mazloom, V. Krutyanskiy +7
Trapped atomic ions embedded in optical cavities are a promising platform to enable long-distance quantum networks and their most far-reaching applications. Here we achieve and ana…
Slow dynamics of salol: a pressure and temperature dependent light scattering study
L. Comez, S. Corezzi, D. Fioretto +3
We study the slow dynamics of salol by varying both temperature and pressure using photon correlation spectroscopy and pressure-volume-temperature measurements, and compare the beh…
Non-dynamic origin of the acoustic attenuation at high frequency in glasses
G. Ruocco, F. Sette, R. Di Leonardo +7
The sound attenuation in the THz region is studied down to T=16 K in glassy glycerol by inelastic x-ray scattering. At striking variance with the decrease found below 100 K in the…
High-performance versatile setup for simultaneous Brillouin-Raman micro-spectroscopy
F. Scarponi, S. Mattana, S. Corezzi +13
Brillouin and Raman scattering spectroscopy are established techniques for the nondestructive contactless and label-free readout of mechanical, chemical and structural properties o…
Intra-molecular origin of the fast relaxations observed in the Brillouin light scattering spectra of molecular glass-formers
G. Monaco, S. Caponi, R. Di Leonardo +2
The Brillouin light scattering spectra of the o-terphenyl single crystal are compared with those of the liquid and the glass phases. This shows: i) the direct evidence of a fast re…
Quantum interferences and gates with emitter-based coherent photon sources
I. Maillette de Buy Wenniger, S. C. Wein, D. Fioretto +10
Quantum emitters such as quantum dots, defects in diamond or in silicon have emerged as efficient single photon sources that are progressively exploited in quantum technologies. In…
Effect of Polymerization on the Boson Peak, from the Liquid to Glassy Phase
S. Caponi, S. Corezzi, D. Fioretto +3
Raman scattering measurements are used to follow the modification of the vibrational density of states in a reactive epoxy{amine mixture during isothermal polymerization. Combining…
Hard sphere-like dynamics in a non hard sphere liquid
T. Scopigno, R. Di Leonardo, L. Comez +3
The collective dynamics of liquid Gallium close to the melting point has been studied using Inelastic X-ray Scattering to probe lengthscales smaller than the size of the first coor…
Probing the dynamics and coherence of a semiconductor hole spin via acoustic phonon-assisted excitation

Spins in semiconductor quantum dots are promising local quantum memories to generate polarization-encoded photonic cluster states, as proposed in the pioneering Rudolph-Lindner sch…
Inelastic x-ray scattering reveals the ergodic to nonergodic transition of salol, a liquid with local order
L. Comez, D. Fioretto, J. Gapinski +3
We have studied the high-frequency dynamics of salol by inelastic x-ray scattering over a wide temperature range between 50 and 450 K, across the glass transition. We find that sal…
