【T. D. Lee Colloquium No.31】The Two Quantum Revolutions

by Prof. Imad Laktineh (the University of Lyon)

Thursday 23 Apr 2026, 14:00 → 15:00 Asia/Shanghai

Tsung-Dao Lee Institute/S5F-S500 - Lecture Hall (Tsung-Dao Lee Institute)

Host: Prof. Xiaogang He （何小刚）

Abstract:
Although the revolution of the Quantum Mechanics took place more than one century ago, many questions remain unanswered and several of its paradoxes are not only still alive but help contribute to the so-called second quantum revolution.  In this colloquium, we will go back to the first steps of QM reminding its intriguing features. The historical debates and the different proposed interpretations will be presented. EPR paradox and the Bell inequalities will then be introduced and used to explain the exciting quantum activities that are ongoing. Quantum cryptography, Qubits and quantum computing as well as quantum sensors will be then presented and a few examples will be given.

 

Bio:
Imad Laktineh is a distinguished professor at the University of Lyon. After a PhD in theoretical physics, he joined the LEP experiments (DELPHI and L3) working on b-quark physics and SUSY searches respectively. After LEP, he joined OPERA collaboration to study neutrino oscillations. Since 2006, his main activities are on detector R&D for the experiments of future high-energy colliders (HL-LHC, ILC, CEPC and FCCee). He developed the concept of the Semi-Digital Hadronic Calorimeter SDHCAL and led the construction of the first technological prototype of the CALICE collaboration using this concept. He is currently working on T-SDHCAL with timing information to improve on the Particle Flow Algorithms (PFA) techniques. He initiated the CMS-iRPC project proposing a new RPC readout concept. He developed a new technique for muon tomography using (M)RPC detectors. He recently invented the PICMIC concept that intends to fully exploit both the excellent spatial and time resolutions of the MCP devices. In parallel, he is developing similar devices with much better performances named NCP for Nano Channel Plates. Pr. Laktineh is very active in the new DRD collaborations with leading roles in DRD1 (gaseous detectors), DRD4 (photo-detection) and DRD6 (calorimetry). He was served as a scientific adviser of the CNRS-IN2P3 for innovative detectors and quantum technologies. He was named a CNRS Ambassador for Innovation in 2025.
