In model-dimension certification tasks, we show that the relative-belief procedure typically chooses Hilbert spaces that are never smaller in dimension than those selected from optimizing a broad class of information criteria, including Akaike's criterion. As a concrete and focused exposition of this powerful evidence-based technique, we apply the relative-belief procedure to an important application: . In particular, just by comparing prior and posterior probabilities based on data, we demonstrate its capability of tracking multiphoton emissions using (realistically lossy) single-photon detectors in order to assess the actual quality of photon sources without making  assumptions, thereby reliably safeguarding source integrity for general quantum-information and communication tasks with Bayesian reasoning. Finally, we discuss how relative belief can be exploited to carry out parametric model certification and estimate the total dimension of the quantum state for the combined (measured) physical and interacting external systems described by the Tavis-Cummings model.</jats:p>\r\n          <jats:sec>\r\n            <jats:title/>\r\n            <jats:supplementary-material>\r\n              <jats:permissions>\r\n                <jats:copyright-statement>Published by the American Physical Society</jats:copyright-statement>\r\n                <jats:copyright-year>2024</jats:copyright-year>\r\n              </jats:permissions>\r\n            </jats:supplementary-material>\r\n          </jats:sec>"}],"department":[{"_id":"15"},{"_id":"623"}],"user_id":"27150","_id":"63219","language":[{"iso":"eng"}],"article_number":"012231","issue":"1","publication_identifier":{"issn":["2469-9926","2469-9934"]},"publication_status":"published","intvolume":"       110","citation":{"chicago":"Teo, Y.

In this contribution, the notion of a driven Gaussian quantum walk is introduced. In contrast to typically considered quantum walks in optical settings, we describe the operation of the walk in terms of a nonlinear map rather than a unitary operation, e.g., by replacing a beam-splitter-type coin with a two-mode squeezer, being a process that is controlled and driven by a pump field. This opens previously unattainable possibilities for quantum walks that include nonlinear elements as core components of their operation, vastly extending their range of applications. A full framework for driven Gaussian quantum walks is developed, including methods to dynamically characterize nonlinear, quantum, and quantum-nonlinear effects. Moreover, driven Gaussian quantum walks are compared with their classically interfering and linear counterparts, which are based on classical coherence of light rather than quantum superpositions. In particular, the generation and boost of highly multimode entanglement, squeezing, and other quantum effects are studied over the duration of the nonlinear walk. Importantly, we prove the quantumness of the evolution itself, regardless of the input state. A scheme for an experimental realization is proposed. Furthermore, nonlinear properties of driven Gaussian quantum walks are explored, such as amplification that leads to an ever increasing number of correlated quantum particles, constituting a source of new walkers during the walk. Therefore, a concept for quantum walks is proposed that leads to—and even produces—directly accessible quantum phenomena, and that renders the quantum simulation of nonlinear processes possible."}],"publication":"Physical Review A","title":"Driven Gaussian quantum walks","date_created":"2022-04-20T06:38:07Z","publisher":"American Physical Society (APS)","year":"2022","issue":"4","article_number":"042210","article_type":"original","user_id":"68236","department":[{"_id":"623"},{"_id":"15"},{"_id":"170"},{"_id":"706"},{"_id":"288"},{"_id":"230"},{"_id":"429"},{"_id":"35"}],"project":[{"_id":"56","name":"TRR 142 - C: TRR 142 - Project Area C"},{"name":"TRR 142: TRR 142","_id":"53"}],"_id":"30921","status":"public","type":"journal_article","main_file_link":[{"url":"https://journals.aps.org/pra/abstract/10.1103/PhysRevA.105.042210"}],"doi":"10.1103/physreva.105.042210","author":[{"last_name":"Held","full_name":"Held, Philip","id":"68236","first_name":"Philip"},{"first_name":"Melanie","last_name":"Engelkemeier","full_name":"Engelkemeier, Melanie"},{"last_name":"De","full_name":"De, Syamsundar","first_name":"Syamsundar"},{"first_name":"Sonja","full_name":"Barkhofen, Sonja","id":"48188","last_name":"Barkhofen"},{"first_name":"Jan","id":"75127","full_name":"Sperling, Jan","last_name":"Sperling","orcid":"0000-0002-5844-3205"},{"full_name":"Silberhorn, Christine","id":"26263","last_name":"Silberhorn","first_name":"Christine"}],"volume":105,"date_updated":"2026-01-09T09:50:22Z","citation":{"apa":"Held, P., Engelkemeier, M., De, S., Barkhofen, S., Sperling, J., &#38; Silberhorn, C.
