Resume:
Ludovic Berthier received his Ph.D. in Theoretical Physics in 2001 at the Ecole Normale Supérieure in Lyon, France. He was a Marie Curie Postdoctoral Fellow at the Department of Theoretical Physics at Oxford University until 2003. In 2004 he was appointed as a CNRS researcher at the Laboratoire Charles Coulomb at University of Montpellier (France), where he is now Director of Research.

I am an Associate Professor (Profesor Titular de Universidad) at Universidad de Sevilla, Spain (3 sexenios, 1 quinquenio, 4 trienios). My research is focused on quantum optics and quantum information, including proposals for quantum simulations with trapped ions and superconducting circuits. I am also interested in quantum artificial intelligence and quantum machine learning, as well as in the emulation of biological behaviours with quantum controllable systems. I enjoy working with experimentalists, and have made proposals and participated in 16 experiments in collaboration with up to 17 prominent experimental groups in quantum science.
Before Sevilla, I worked in Bilbao, at the University of the Basque Country, as a Marie Curie postdoctoral fellow and subsequently with a Ramón y Cajal position and a Staff Scientist position. Earlier, I was a Humboldt Fellow and a Max Planck postdoctoral fellow for 3 and a half years at the Max Planck Institute for Quantum Optics in Garching, Germany. Previously, I carried out my PhD at CSIC, Madrid, and Universidad Autónoma de Madrid. I have 19-year research experience in centers of Spain and Germany, having performed research as well with scientific collaborations in several one- or two-week stays in centers from all continents as Harvard University, ETH Zurich, Google/University of California Santa Barbara, Shanghai University, Tsinghua University, Macquarie University, Walther-Meissner Institut Garching, IQOQI Innsbruck, among others.

Signal processing and image classification with an array of nanolasers
Photonic artificial neural networks are causing a revolution in artificial intelligence systems because they have the potential to be much faster and more energy efficient than current silicon technology. In these big data days where data centers and high-performance computing systems consume enormous amounts of energy, energy-efficient systems are urgently needed. A most attractive candidate for photonic neural networks is a nanolaser, because nanolaser arrays are scalable and can provide high performance with ultra-low power consumption. In this talk, I will discuss a novel protocol that exploits the symmetry properties of the collective modes of an array of nanolasers, for binary image classification. Through simulation of a simple model, I will show that, under appropriate conditions, when spatially modulated pump patterns are applied to the laser array via a computer-based linear transformation of an input image, only a given class of images efficiently excites a zero mode of the array. As a proof-of-concept demonstration, we analyzed images of handwritten digits and obtained overall accuracies of 98% for one-versus-all classifiers (G. Tirabassi et al, APL Photon. 7, 090801 2022; doi: 10.1063/5.0100049).

I am interested in theoretical problems at the interface of physics and biology. I want to understand how large-scale, collective behaviors observed in biological systems emerge from the interaction of many individual molecular elements, and how these interactions allow cells to perform complex computations in response to environmental cues. I am also a part of the BU Bioinformatics Program and the BUMC Center for Regenerative Medicine (CReM) , and the BU Biological Design Center.

Professor Whaley’s research is at the interfaces of chemistry with physics and with biology. Her work is broadly focused on quantum information and quantum computation, control and simulation of complex quantum systems, and quantum effects in biological systems. Quantum information processing employs superposition, entanglement, and probabilistic measurement to encode and manipulate information in very different ways from the classical information processing underlying current electronic technology. Theoretical research of Professor Whaley’s group in this area is focused in quantum control, quantum information and quantum measurement, analysis and simulation of open quantum systems, macroscopic quantum states and quantum metrology. Specific topics of current interest include quantum feedback control, quantum reservoir engineering, topological quantum computation, and analysis of macroscopic quantum superpositions in interacting many-body systems. Such superposition states, dramatically illustrated by Schrodinger’s famous cat paradox, offer unprecedented opportunities for precision measurements. Professor Whaley’s recent research in quantum biology seeks to characterize and understand the role of quantum dynamical effects in biological systems, with a perspective that combines physical intuition and detailed quantum simulation with insights from various branches of quantum science – quantum physics, molecular quantum mechanics and quantum information.
