Quantiki

PenteQost-25 is the second edition of the interdisciplinary and international undergraduate spring school on the Fundamentals of Quantum Science. Building on the success of the inaugural event, the school will once again be hosted by the University of Siegen, taking place from Friday afternoon, June 6, to Tuesday noon, June 10, 2025. Timed to align with the Pentecost weekend, the program minimizes conflicts with regular semester schedules.

“Beyond IID in Information Theory” started as a workshop in Cambridge, organised by Nilanjana Datta and Renato Renner as a forum for the growing interest in new approaches in quantum information theory to obtain coding theorems in the finite block length regime. Since then, it has grown both in scope and size, now being the most prominent annual conference dedicated to quantum Shannon theory and its applications in quantum information science.

The Theory of Quantum Computation, Communication and Cryptography (TQC) is a leading annual international conference for students and researchers working in the theoretical aspects of quantum information science. The scientific objective is to bring together the theoretical quantum information science community to present and discuss the latest advances in the field.

This workshop marks the halfway milestone of the FoQaCiA project, a groundbreaking collaboration between leading researchers from Europe and Canada. Funded through a flagship partnership between Horizon Europe and NSERC, FoQaCiA aims to chart the boundaries between the computational power of quantum devices and classical computers, identifying the "line in the sand" that defines tasks with quantum speedups versus those that remain classically simulable.

Following the highly successful 2024 event, this will be a one week residential conference in two of Oxford’s historic colleges that are located very conveniently next to each other. Experts will gather to debate the challenges and opportunities in the worldwide effort to achieve general Quantum Advantage.
