Implementing a causal measurement scheme \nby Jan Mandrysch (IQOQI-Vienna) as part of Tricontinental Quantum Fundam entals Seminar\n\n\nAbstract\nWhile measurement processes in standard quan tum mechanics are well understood\, the extension of these ideas to quantu m field theory (QFT) remains a key challenge. In particular\, ensuring tha t measurements respect fundamental principles such as relativistic causali ty is crucial. A persistent issue concerning measurements in QFT is\, thou gh\, that microcausality alone is insufficient to prevent superluminal sig naling. In this talk\, I will present a concrete scheme for measuring real linear scalar fields\, grounded in the Fewster-Verch measurement framewor k\, which allows to model projective and Gaussian measurements and more. T he approach fully respects the principles of relativistic covariance\, loc ality\, and causality\, offering a robust solution to the challenges of me asurement in QFT.\n\nTalk has been rescheduled for 12 March 2026 at 10:00 CET.\n LOCATION:https://researchseminars.org/talk/3cqfs/41/ END:VEVENT END:VCALENDAR
