After the first four symposia held in London in 1950, 1952, 1955, and 1960, LSIT was revived and was held again in London in 2019 (King’s College London), in 2021 (Imperial College London), and in 2023 (at University College London). This year LSIT 2025 took place in Cambridge for the first time, at St John’s College in the University of Cambridge, on May 14-16, 2025. The symposium continued the tradition of having free registration. There were 122 registered participants, including 50 students and 22 postdoctoral researchers.
The symposium was single-track and consisted of six invited sessions, on Coding Theory (chaired by Joachim Rosenthal), Communications (chaired by Tobias Koch), Facets of Information Theory and Machine Learning (sponsored by the EPSRC funded AI-hub Informed-AI and chaired by Sid Jaggi), Frontiers of Quantum Shannon Theory (chaired by Mark Wilde) and Hypothesis Testing (chaired by Yuval Kochman); each session had 4 talks.
During the welcome reception a poster session was held, with 20 posters on coding, communications, data compression, machine learning, privacy, probability, quantum information and statistical inference.
In addition, one of the invited sessions was the 2025 Cambridge Information Theory Colloquium, which took place on 15 May 2025 at the Centre for Mathematical Sciences, and included invited talks by:
- Michael Gastpar, on “Information Measures, Universal Prediction, and Large Language Models”
- Emina Soljanin, “On Non-Local Coset-Guessing Quantum Games”
- Anelia Somekh-Baruch, on “Impossibility Results in Channel Coding via Auxiliary Channels and Genie-Aided Techniques”
- and Mark Wilde, on “Quantum Doeblin Coefficients: Interpretations and Applications”.
