For resonant driving, phonons dampen the Rabi oscillations resulting in reduced preparation fidelities. The phonon spectral density, which quantifies the strength of the carrier-phonon interaction, is non-monotonous as a function of energy. As one of the most prominent consequences, this leads to the reappearance of Rabi rotations for increasing pulse power, which was theoretically predicted in Phys. Rev. Lett. 98, 227403 (2007).

Semiconductor quantum dots (QDs) are attractive candidates that emit high-quality quantum states of light on demand, however at a rate limited by their spontaneous radiative lifetime. In this study, we utilize the Purcell effect to demonstrate up to a 38-fold enhancement in the emission rate of InAs QDs by coupling them to metal-clad GaAs nanopillars. These cavities, featuring a sub-wavelength mode volume of 4.5x10-4 (λ/n)3 and low quality factor of 62, enable Purcell-enhanced single-photon emission across a large bandwidth of 15 nm. The broadband nature of the cavity eliminates the need for implementing tuning mechanisms typically required to achieve QD-cavity resonance, thus relaxing fabrication constraints. Ultimately, this QD-cavity architecture represents a significant stride towards developing solid-state quantum emitters generating near-ideal single-photon states at GHz-level repetition rates.","lang":"eng"}],"citation":{"apa":"Jöns, K.

Developing tools to analyze these systems at the relevant scales, in a manner consistent with quantum mechanics, is therefore critical to benchmarking performance and characterizing their operation. While classical computational approaches cannot perform like-for-like computations of quantum systems beyond a certain scale, classical high-performance computing (HPC) may nevertheless be useful for precisely these characterization and certification tasks. By developing open-source customized algorithms using high-performance computing, we perform quantum tomography on a megascale quantum photonic detector covering a Hilbert space of 106. This requires finding 108 elements of the matrix corresponding to the positive operator valued measure (POVM), the quantum description of the detector, and is achieved in minutes of computation time. Moreover, by exploiting the structure of the problem, we achieve highly efficient parallel scaling, paving the way for quantum objects up to a system size of 1012 elements to be reconstructed using this method. In general, this shows that a consistent quantum mechanical description of quantum phenomena is applicable at everyday scales. More concretely, this enables the reconstruction of large-scale quantum sources, processes and detectors used in computation and sampling tasks, which may be necessary to prove their nonclassical character or quantum computational advantage.","lang":"eng"}],"issue":"1","publication":"Quantum Science and Technology","user_id":"55629","volume":10,"_id":"53202","publisher":"IOP Publishing","status":"public","oa":"1","external_id":{"arxiv":["2404.02844"]},"project":[{"name":"PC2: Computing Resources Provided by the Paderborn Center for Parallel Computing","_id":"52"},{"name":"ERC-Grant: QuESADILLA: Quantum Engineering Superconducting Array Detectors in Low-Light Applications","_id":"239"},{"name":"PhoQuant: Photonische Quantencomputer -  Quantencomputing Testplattform","_id":"191"}],"citation":{"short":"T.

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>","lang":"eng"}],"publication":"Physical Review A","issue":"1","user_id":"27150","volume":110,"publisher":"American Physical Society (APS)","_id":"63219","status":"public","citation":{"mla":"Teo, Y.

We introduce a general dimension-certification protocol for both discrete and continuous variables that is fully evidence based, relying solely on the experimental data collected and no other unjustified assumptions whatsoever. Using the Bayesian concept of relative belief, we take the effective dimension of the state as the smallest one such that the posterior probability is larger than the prior, as dictated by the data. The posterior probabilities associated with the relative-belief ratios measure the strength of the evidence provide by these ratios so that we can assess whether there is weak or strong evidence in favor or against a particular dimension. Using experimental data from spectral-temporal and polarimetry measurements, we demonstrate how to correctly assign Bayesian plausible error bars for the obtained effective dimensions. This makes relative belief a conservative and easy-to-use model-selection method for any experiment.</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>"}],"date_created":"2025-12-18T16:13:00Z","department":[{"_id":"15"},{"_id":"623"}],"type":"journal_article","author":[{"first_name":"Y. S.","last_name":"Teo","full_name":"Teo, Y. S."},{"first_name":"S. U.","last_name":"Shringarpure","full_name":"Shringarpure, S. U."},{"full_name":"Jeong, H.","last_name":"Jeong","first_name":"H."},{"id":"71403","first_name":"Nidhin","last_name":"Prasannan","full_name":"Prasannan, Nidhin"},{"orcid":"0000-0003-4140-0556 ","last_name":"Brecht","first_name":"Benjamin","full_name":"Brecht, Benjamin","id":"27150"},{"first_name":"Christine","last_name":"Silberhorn","full_name":"Silberhorn, Christine","id":"26263"},{"last_name":"Evans","first_name":"M.","full_name":"Evans, M."},{"full_name":"Mogilevtsev, D.","last_name":"Mogilevtsev","first_name":"D."},{"full_name":"Sánchez-Soto, L. L.","first_name":"L. L.","last_name":"Sánchez-Soto"}],"publication_identifier":{"issn":["0031-9007","1079-7114"]},"year":"2024","title":"Evidence-Based Certification of Quantum Dimensions","intvolume":"       133","publication_status":"published","date_updated":"2025-12-18T16:13:14Z","language":[{"iso":"eng"}],"article_number":"050204","doi":"10.1103/physrevlett.133.050204"},{"author":[{"full_name":"De, Syamsundar","first_name":"Syamsundar","last_name":"De"},{"first_name":"Vahid","last_name":"Ansari","full_name":"Ansari, Vahid"},{"orcid":"0000-0002-5844-3205","first_name":"Jan","last_name":"Sperling","full_name":"Sperling, Jan","id":"75127"},{"id":"48188","first_name":"Sonja","last_name":"Barkhofen","full_name":"Barkhofen, Sonja"},{"id":"27150","first_name":"Benjamin","last_name":"Brecht","orcid":"0000-0003-4140-0556 ","full_name":"Brecht, Benjamin"},{"id":"26263","first_name":"Christine","last_name":"Silberhorn","full_name":"Silberhorn, Christine"}],"publication_identifier":{"issn":["2643-1564"]},"title":"Realization of high-fidelity unitary operations on up to 64 frequency bins","year":"2024","intvolume":"         6","date_updated":"2025-12-18T16:14:39Z","publication_status":"published","language":[{"iso":"eng"}],"article_number":"L022040","doi":"10.1103/physrevresearch.6.l022040","publication":"Physical Review Research","issue":"2","abstract":[{"text":"<jats:p>The ability to apply user-chosen large-scale unitary operations with high fidelity to a quantum state is key to realizing future photonic quantum technologies.

For entangled two photon absorption in particular, very high photon flux combined with high time-frequency entanglement is crucial for observing a signal. So far these conditions could be met by using high power lasers driving degenerate, type 0 bulk-crystal spontaneous parametric down conversion (SPDC) sources. This naturally limits the available wavelength ranges and precludes deterministic splitting of the generated output photons. In this work we demonstrate an integrated two-colour SPDC source utilising a group-velocity matched lithium niobate waveguide, reaching both exceptional brightness 1.52⋅10<jats:sup>6</jats:sup>pairssmWGHz and large bandwidth (7.8 THz FWHM) while pumped with a few mW of continuous wave (CW) laser light.
