AMER CHEMICAL SOC2023Measurement-induced collective vibrational quantum coherence under spontaneous Raman scattering in a liquid
Christophe Marcel Georges Galland, Valeria Vento, Anna Pogrebna
Spontaneous Raman scattering is classically understood as an incoherent process. Here, the authors demonstrate that macroscopic quantum coherence among billions of vibrating molecules in a liquid is generated when single photon detection and single spatio- ...
2023Microscopic origin of polarization-entangled Stokes-anti-Stokes photons in diamond
Christophe Marcel Georges Galland
Time-correlated Stokes-anti-Stokes (SaS) scattering has been studied in different transparent media, more frequently in diamond. While the nonclassical nature of the SaS scattered photons has been well established, the presence of entanglement in this spon ...

We report the experimental nondemolition measurement of coherence, predictability and concurrence on a system of two qubits. The quantum circuits proposed by De Melo et al. (Phys Rev Lett 98(25):250501, 2007) are implemented on IBM Q (superconducting circu ...
SPRINGER2022Assessment of the Bundle SNSPD Plus FPGA-Based TDC for High-Performance Time Measurements
Christophe Marcel Georges Galland, Andrea Costa
Counting single photons and measuring their arrival time is of crucial importance for imaging and quantum applications that use single photons to outperform classical techniques. The investigation of the coincidence, i.e. correlation, between photons can b ...
IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC2022Measurement-Induced Collective Vibrational Quantum Coherence under Spontaneous Raman Scattering in a Liquid
Christophe Marcel Georges Galland, Valeria Vento, Santiago Tarrago Velez, Anna Pogrebna
Spontaneous vibrational Raman scattering is a ubiquitous form of light-matter interaction whose description necessitates quantization of the electromagnetic field. It is usually considered as an incoherent process because the scattered field lacks any pred ...
