Divide and conquer: variations on beamsplitting in quantum optics

Dr. Nadia Belabas has been a CNRS researcher since 2004. She is an expert notably in semiconductor nanophotonics, quantum optics and photonic circuitry. She initially worked on broadband pulse-shaping, Fourier transform and multidimensional nonlinear spectroscopy. She then opened prospects in integrated classical and quantum photonics with innovative guided light manipulation and new parametric sources. Since 2016 she proposed and implemented quantum tasks with nonlinear waveguide arrays, semiconductors parametric and on-demand sources and beyond, both in the continuous and discrete variable framework. Her current interests include time-frequency encoding of quantum information and quantum fibered implementations in the telecom wavelength regime.

Quantum Fisher information metric for quantum machine learning

Dr. Tobias Haug is senior researcher at TII in Abu Dhabi, UAE. He received his PhD from the Centre for Quantum Technology in Singapore in 2021. During his PhD he worked at NTT in Japan and Entropica Labs in Singapore. After his PhD he was a postdoctoral researcher at Imperial College London. His research focuses on quantum algorithms, quantum machine learning, quantum cryptography, quantum error correction and resource theories of magic.

Prof. Antoine (Jack) Jacquier is a Professor of Mathematics at Imperial College London. He holds a Masters Degree from ESSEC Business School and a PhD in Mathematics from Imperial College London. His research broadly focuses on the developments and applications of mathematical theories to quantitative finance, ranging from stochastic analysis to numerical analysis and quantum computing. Prof. Jacquier also serves as a scientific consultant and advisor for various finance and technology companies.

Prof. Dr. Fedor Jelezko is currently a director of the Institute of Quantum Optics at Ulm University, director of the Centre for Integrated Quantum Science and Technology and member of Heidelberg Academy of Sciences.
He studied in Minsk (Belarus) and received his Ph.D. in 1998. After finishing the habilitation in 2010 at Stuttgart University he was appointed as a professor of experimental physics in Ulm in 2011. His research interests are at the intersection of fundamental quantum science and quantum technologies. His research team is exploring applications of spin qubits in diamond for information processing, communication, sensing, and imaging.
Outside academia, he is involved in the development of quantum technologies based on spin qubits. Fedor Jelezko and his team could show that it is possible to create a hyperpolarization of nuclear spins in diamond or external molecules under ambient conditions. Such diamonds become visible in standard MRI machines and thus offer new perspectives for enhanced medical imaging. Having applied for a patent on this idea, Prof. Jelezko and his colleagues are now pursuing its exploitation by means of their start-up company NVision Imaging Technologies GmbH.

Prof. Anand Kumar Jha obtained his 5 years’ integrated MSc in Physics from IIT Kharagpur in 2002 and his PhD from the University of Rochester in 2009. After doing a postdoc for about a year at the University of Rochester, Dr. Jha worked with Intel corporation for about two years and then joined IIT Kanpur as an assistant professor of Physics in 2013. Since 2022, he has been a professor of Physics at IIT Kanpur. Dr. Jha has setup a “quantum optics and entanglement” laboratory at IIT Kanpur and carries out research in the broad areas of classical & quantum coherence, quantum entanglement, and quantum imaging.

Prof. Bhaskar Kanseri is working as IHFC chair professor at Department of Physics and a joint faculty at Optics and Photonics Center (OPC), IIT Delhi. Prior joining IITD, he was postdoctoral fellow at Institut d’Optique, Palaiseau France, and earlier at Max Planck Institute for the Science of Light, Erlangen Germany. He received his PhD from University of Delhi and National Physical Laboratory, New Delhi. He has more than 75 publications in peer-reviewed international journals and about 160 conference presentations and invited lectures in his credit. He has been awarded “Teaching excellence award-2022” and “Veena Arora Early Career Research Award-2022” by IIT Delhi for his teaching and research contributions. In 2023, he has been selected as member of The National Academy of Sciences India (NASI), and Associate fellow at the Indian National Science Academy (INSA). His notable contributions in Quantum security domain are realization of the longest quantum secure communication in the country in both fibre channel and in free-space channel. Currently, he is pioneering entanglement-based quantum network activities at IIT Delhi.

Prof. Marcin Pawłowski obtained his PhD in physics at University of Gdańsk in 2010. Later he worked as a post-doc at University of Bristol from which he returned to Gdańsk in 2013 to start his own research group. Currently he is the head of Quantum Cybersecurity and Communication group at International Centre for Theory of Quantum Technologies. The topics oh his research range from quantum foundational, through quantum cryptography, to machine learning. His work also focuses on the simplification of quantum algorithms to make them more efficient and realizable with simpler experimental setups. He is also a founder of two startup companies: QCG – which delivers comprehensive cryptographic solutions, and SeQure Quantum – which builds device independent random number generators.

Superconducting quantum electrical circuits: a platform for technology and fundamental science.

Dr. Vijayaraghavan is currently an Associate Professor at the Tata Institute of Fundamental Research, Mumbai and heads the Quantum Measurement and Control Laboratory where the research focuses on superconducting quantum circuits. He is currently leading several projects to build small to medium scale quantum processors with funding from DAE, DRDO, TCS and DST. He is also the Lead PI for the Technical Group working on building superconducting quantum computers under the National Quantum Mission. He is a recipient of the Ramanujan Fellowship (2013-18) awarded by the Department of Science and Technology of the Government of India, and a Fellow of the Indian Academy of Sciences, Bangalore since January 2024. He was awarded the Pancharatnam prize for excellence in quantum science and technology by the Government of Karnataka in July 2025.

Prof. Sai Vinjanampathy completed his Ph.D. in 2010 from Louisiana State University, USA. Thereafter, he was a postdoctoral fellow in University of Massachusetts, Boston from 2010 to 2012 and then at the Centre for Quantum Technologies Singapore from 2012 to 2016. Since July 2016, he has been a faculty member in the Physics department at IIT Bombay. His group works on the physics of quantum technologies, exploring diverse topics from nonlinear dynamics of quantum systems, exotic phase transitions and novel sensor designs.
