The third edition of this series of Workshops was held in Burgos from October 2 to October 6, 2023, and brought together experts in Quantum Foundations, Quantum Information Theory, Quantum Gravity, and Philosophy of Physics, fostering open discussions on various aspects of the notion of observer. The aim of the present edition was to continue our exploration of recent developments in this rapidly evolving field.  This Workshop provided a dynamic discussion forum, with a specific emphasis on applications and connections with Quantum Communication Protocols and Systems.

The XIV International Summer School on Geometry, Mechanics and Control will be held in Burgos, Spain, from July 4 to July 8, 2022. The School is organised by the Geometry, Mechanics and Control (GMC) Network and the Mathematical Physics Group of the Universidad de Burgos.

This school is oriented to young researchers, Ph.D. and postdoctoral students in Mathematics, Physics and Engineering, whose research topics deal with Geometry, Mechanics and Control Theory. In particular, this year the courses of the School will be focused in spectral geometry, Lie systems and their geometric structures, quantum groups and non-commutative geometry and geometric control. These courses are intended to present an up-to-date introduction to these topics, and also to bring the participant´s attention to some open problems, in particular those ones related to applications. Undegraduate students and master students are also welcome. Participants are encouraged to present oral or poster contributions.

This virtual meeting on topics of geometry, mechanics, control and their connections will take place from March 7th to 11th, 2022. Registration is open, including proposals for short talks and poster contributions.
