The organisers thank everyone\, speakers\, partici pants\, and all the helping hands for the great experience!\nIf you want m ore quantum\, consider the upcoming events from our project partners at th e University of Gdánsk\, Poland:\n\nThe Workshop on the Physics of Quantu m Chips (PQC) 2026\, taking place Aug 24--26 at the University of Gdánsk. \nThe Q-Con conference: Quantum\, Applied. Value\, Delivered. A business- focused conference on quantum technologies\, taking place on Sep 11th in G dánsk.\nThe Q-Camp Quantum Summer School 2026\, an in-depth two-week summ er academy on quantum technologies\, taking place Aug 31 -- Sep 10 in Gdá nsk.\n\n \n\nPenteQost-26 is the third edition of our interdisciplinary a nd international undergraduate spring school on the Fundamentals of Quantu m Science. Building on the success of the first two editions in Siegen\, t his year the event will once again be hosted by the University of Siegen\, Germany\, in cooperation with the University of Gdánsk\, Poland\, funded by the Federal Ministry of Research\, Technology and Space (BMFTR) within the project MasterQE. \nThe school will take place from Friday afternoo n\, 22 May\, to Tuesday noon\, 26 May 2026\, during the long Pentecost wee kend so that it does not overlap with regular summer-semester lectures at German universities. Students\, graduates\, and professionals are welcome to join us in exploring quantum science and its technological applications through lectures\, interactive discussions\, and collaborative sessions i n an international setting.\nTopics & Speakers\nYou will learn the theoret ical fundamentals and the experimental practice of quantum science and tec hnology\, which includes:\nQuantum Foundations & Open Quantum Systems: Exp lore the fundamental principles of quantum mechanics with a focus on open quantum systems. Learn how interactions with the environment affect quantu m dynamics and how these effects can be modeled using completely positive maps and master equations. Understand the role of noise and decoherence an d their impact on quantum technologies.\nBell Inequalities & Quantum Nonlo cality:Learn how Bell inequalities are used to test quantum nonlocality an d to distinguish classical from quantum correlations. Topics may include t he formulation of Bell experiments\, interpretation of violations\, and co nnections to entanglement and quantum information tasks.\nSemidefinite Pro gramming in Quantum ScienceLearn how semidefinite programming provides a p owerful optimization framework for problems in quantum information and qua ntum foundations. Applications include the characterization of quantum sta tes and channels\, entanglement detection\, Bell inequalities\, and bounds in quantum metrology and complexity theory.\nQuantum Computation and Comp utational Complexity:Develop an understanding of the computational power a nd limitations of quantum systems. Topics may include basic models of quan tum computation\, the role of entanglement in algorithms\, and how complex ity theory is used to classify computational problems in classical and qua ntum settings.\nQuantum Technologies and Precision Measurements:Learn abou t experimental platforms and techniques used in contemporary quantum techn ologies. This may include trapped-ion systems\, precision spectroscopy\, a nd quantum-enhanced measurement schemes\, with applications ranging from t imekeeping to tests of fundamental physics.\nAll lectures will be given in  English\, and you will interact with leading international scientists in the respective fields.\nConfirmed speakers:\n\n\nAlessandra Colla (Univer sity of Freiburg) – works on the theory of open quantum systems and non- equilibrium quantum thermodynamics\, including irreversibility and entropy production\, and related aspects of non-Markovian dynamics\n\n\nMaría Ga rcía Díaz (Universidad Politécnica de Madrid / MathQI\, Universidad Com plutense de Madrid) – works on quantum information and quantum foundatio ns\, with research interests including open quantum systems\, quantum cohe rence\, and quantum simulation.\n\nLina Vandré (TU Vienna\, neQxt) – wo rks on quantum error correction and quantum communication networks\, speci fically on stabilizer states and graph representations\n\nMatthias Kleinma nn (University of Münster) – works on quantum information theory and t he foundations of quantum theory\, including Bell inequalities\, contextua lity\, and the characterization of non-classical correlations.\n\n\nPatric k Huber (University of Siegen) – works in experimental quantum optics wi th trapped ions\, including quantum information experiments and control te chniques in trapped-ion platforms.\n\n\n Gizéh Rangel-de Lázaro (Univer sidad de Málaga)– cross-disciplinary specialist in museistics and the s tudy of anthropological\, archaeological\, and natural sciences museum col lections by using digitisation\, AI\, and immersive reality approaches\n\n \n \nInterested? Register HERE.\nTarget Audience & Prerequisites\nIntern ational undergraduate or graduate students from all fields of study are we lcome\, as well as interested professionals and freelancers\, with an inte rest in modern quantum science and technology. \nWe recommend that you ha ve essential knowledge of linear algebra and analysis\, as typically taugh t in introductory undergraduate math courses. We also recommend that you f amiliarize yourself with the basic concepts of quantum physics beforehand. For example\, you may already have attended a quantum physics lecture in your university before. If not\, we can recommend the following online cou rses and textbooks:\n\n(Book) "Quantum Computation and Quantum Information " by M. Nielsen and I. L. Chuang – Chapters 1 and 2.\n(Online resource) "Quantum computing for the very curious" and "Quantum mechanics distilled" by A. Matuschak and M. Nielsen\n(Video lectures) "Introduction to Quantum Information Science" by A. Ekert – Lectures 1 to 4.\n\nGraduate student s with advanced knowledge in quantum science are welcome to participate\, but they should note that this school is aimed at the introductory level.\ nHosts\nThe PenteQost school is jointly organized by quantum scientists Gi ulio Gasbarri\, Stefan Nimmrichter\, and Otfried Gühne at the University of Siegen and Paweł Mazurek at the University of Gdánsk in Poland.\nThe responsible research group in Siegen is led by Otfried Gühne\, together w ith the PIs Chau Nguyen and Stefan Nimmrichter. We investigate all aspects of quantum foundations\, quantum information theory\, and quantum metrolo gy. On the experimental side\, Christof Wunderlich’s research group is d eveloping a cutting-edge platform for quantum computing with trapped ions. The recently founded the spin-off company eleQtron is currently developin g chips based on this platform.\nCheck out also our new "Quantum Science" master program\, an interdisciplinary Master study program open for intern ational students with a Bachelor’s degree in physics\, mathematics\, com puter science\, and electrical engineering.\nSiegen is located centrally i n Germany\, around 125km northwest of Frankfurt and 90km east of Cologne. It can be easily reached via train or car\, and nearby international airpo rts are in Frankfurt\, Cologne\, and Düsseldorf. Downtown Siegen offers m any pubs\, restaurants and cafes\, but also theaters\, cinemas and concert halls. Further travel information can be found in the side menu.\nFinanci al support\nFinancial support will be provided for selected students. The exact amount will be defined depending on the final number of applicants\, but should be enough to cover a large part of the expenses. Non-student p articipants cannot be granted financial support.\nTLDR\n\nWhat: Interdisci plinary and international school on Fundamentals of Quantum Science (quant um foundations\, quantum cryptography\, quantum computing\, quantum comple xity theory\, trapped ions etc.)\nFor whom: Interested undergraduate and g raduate students\, working professionals\, freelancers with a basic unders tanding of linear algebra and elementary quantum mechanics.\nWhen: Friday afternoon\, May 22\, to Tuesday noon\, May 26\, 2026\; registration deadl ine is May 1\, 2026\, at 23:59 (Berlin time).\nWhere: University of Siegen \, Germany\, conveniently located between Frankfurt and Cologne.\n\nRegist er HERE\n\nhttps://indico.physik.uni-siegen.de/event/853/ LOCATION:University of Siegen URL:https://indico.physik.uni-siegen.de/event/853/ END:VEVENT END:VCALENDAR
