His papers have been cited about 5200 (7200) times and score an h-index of 35 (41) according to Scopus (Google Scholar), November 2023.

Main scientific interests:

  • Quantum Optics: generation, engineering, and characterization of nonclassical states of light for novel quantum technologies
  • Quantum information processing and communication: development of experimental tools and procedures for continuous-variable protocols and field tests of quantum key distribution
  • Tests of fundamental principles in quantum mechanics: non-classicality, entanglement, nonlocality, commutation rules, etc.
  • Development, characterization, and applications of novel coherent sources in the extreme ultraviolet (XUV) based on high-order laser harmonics
  • High-intensity laser-matter interactions and generation of supercontinuum
  • Spectroscopy with ultrashort laser pulses and development of novel techniques for high-resolution atomic spectroscopy
  • High-precision atomic and molecular spectroscopy and development of novel coherent sources in the far infrared (FIR-THz)
  • Optical coherence tomography for advanced diagnostics in medicine and for the cultural heritage

Main scientific achievements:

  • 1997 Demonstration of phase coherence in supercontinuum generation: fundamental discovery for the generation of trains of phase-locked supercontinuum pulses. It led to the development of frequency combs, later awarded of the 2005 Nobel prize in Physics to Theodor W. Hänsch, co-author of the research.
  • 1997-1998 Demonstration of phase coherence in high-order harmonic generation: it proved the role of the different electron trajectories in the harmonic generation process and led to the development of attosecond pulses and to the birth of attophysics, for which Anne L’Huillier, co-author of the research, was awarded the 2023 Nobel prize in Physics.
  • 2000-2002 Demonstration of XUV interferometry and high-resolution XUV spectroscopy with high-order harmonics: it opened the field to the now widespread use of laser harmonic sources for applications in the XUV and soft X-ray regions.
  • 2004 Experimental realization of the photon creation operator: first implementation of a fundamental quantum process for advanced state engineering and first exploration of the quantum-to-classical transition for light states.
  • 2006 First application of Optical Coherence Tomography to artwork diagnostics: after this pioneering demonstration in ancient painting analysis, OCT has now become a widespread and privileged tool for cultural heritage diagnostics.
  • 2007 Direct verification of non-commutativity of quantum operators: the first realization of arbitrary sequences and superpositions of simple quantum operators was a breakthrough for the fundamental understanding of quantum physics and as a new tool for quantum technologies.
  • 2011 Realization of high-fidelity quantum noiseless amplification: using a non-deterministic scheme to avoid the addition of quantum noise to the amplification process, it promises more efficient methods for quantum information processing and communication.
  • 2012 Shaping of ultrashort single photons: thanks to an innovative merge of the fields of ultrafast and quantum optics, it demonstrated the possibility of encoding quantum information in the spectrotemporal mode of quantum light states.
  • 2013 Femtosecond laser writing of graphitic electrodes in diamond: this new technique holds promise of leading to the realization of 3D diamond detectors for high-energy physics and biomedical applications.
  • 2014 First hybrid quantum/classical entangled states of light: experimental realization of the optical version of Schrodinger’s cat paradox. A fundamental scientific breakthrough and a possible main ingredient of future heterogeneous quantum networks.
  • 2015 Noise-assisted transport in an optical network: a simple, scalable, and controllable optical fiber cavity network to simulate quantum transport phenomena.
  • 2015 First arbitrary state orthogonalizer and qubit generator: a “Schrödinger’s pet” machine, able to turn a whole zoo of input states into coherent superpositions for innovative quantum technologies and measurement tasks.
  • 2016 Demonstration of zero-area single-photon pulses: a single broadband photon of extremely short duration can be strongly modulated by interacting with resonant atoms.
  • 2020 Entanglement of macroscopic light pulses: the delocalized addition of a single photon can entangle two separate laser pulses containing an average of up to 60 photons each.
