In this work, we develop a systematic approach for constructing and analyzing χ-colorable graph states, deriving explicit closed-form expressions for arbitrary χ. For a broad family of two- and three-colorable graph states, the representations obtained using only local operations require a minimal number of terms in the Z-eigenbasis. We prove that every two-colorable graph state is local Clifford (LC) equivalent to a state expressible as a summation of rows of an orthogonal array (OA). For graph states with χ > 2, we show that they are LC-equivalent to quantum OAs, establishing a direct combinatorial connection between multipartite entanglement and structured quantum states. Furthermore, the upper and lower bounds of the Schmidt measure for graph states with arbitrary χ colorability are discussed, extending the results for an arbitrary local dimension. Our results offer an efficient and practical method for systematically constructing graph states, optimizing their representation in quantum circuits, and identifying structured forms of multipartite entanglement. This approach also connects graph states to k-uniform and absolutely maximally entangled states, motivating further exploration of the structure of entangled states and their applications in quantum networks, quantum error correction, and measurement based quantum computing."}],"file":[{"creator":"zraissi","date_created":"2026-02-09T15:35:25Z","date_updated":"2026-02-09T15:35:25Z","file_name":"Revis_2025_J._Phys._A%3A_Math._Theor._58_355301.pdf","access_level":"closed","file_id":"64082","file_size":749441,"content_type":"application/pdf","relation":"main_file","success":1}],"ddc":["004"],"language":[{"iso":"eng"}],"issue":"35","year":"2025","publisher":"IOP Publishing","date_created":"2026-02-09T15:35:00Z","title":"χ-colorable graph states: closed-form expressions and quantum orthogonal arrays"},{"intvolume":" 112","citation":{"ieee":"H.

Meanwhile, the existing methods of its characterization are technically complicated, which reduces the level of squeezing, and mostly deal with a single mode at a time. Here, for the first time, to the best of our knowledge, we employ optical parametric amplification to characterize multiple squeezing eigenmodes simultaneously. We retrieve the shapes and squeezing degrees of all modes at once through direct detection followed by modal decomposition. This method is tolerant to inefficient detection and does not require a local oscillator. For a spectrally and spatially multimode squeezed vacuum, we characterize eight strongest spatial modes, obtaining squeezing and anti-squeezing values of up to −5.2 ± 0.2 dB and 8.6 ± 0.3 dB, respectively, despite the 50% detection loss.

In this paper, we propose a novel distributed algorithm that enables a group of modules to reconfigure into a rhombus shape, starting from an arbitrary side-connected configuration. It is connectivity-preserving and operates under minimal assumptions: one leader module, common chirality, constant memory per module, and visibility and communication restricted to immediate neighbors. Unlike prior work, which relaxes the original sliding square move-set, our approach uses the unmodified move-set, addressing the additional challenge of handling locked configurations. Our algorithm is sequential in nature and operates with a worst-case time complexity of O(n^2) rounds, which is optimal for sequential algorithms. To improve runtime, we introduce two parallel variants of the algorithm. Both rely on a spanning tree data structure, allowing modules to make decisions based on local connectivity. Our experimental results show a significant speedup for the first variant, and a linear average runtime for the second variant, which is worst-case optimal for parallel algorithms.","lang":"eng"}],"publication":"Stabilization, Safety, and Security of Distributed Systems","doi":"10.1007/978-3-032-11127-2_26","conference":{"location":"Kathmandu","end_date":"2025-10-11","start_date":"2025-10-09","name":"27th International Symposium on Stabilization, Safety, and Security of Distributed Systems (SSS)"},"author":[{"first_name":"Irina","last_name":"Kostitsyna","full_name":"Kostitsyna, Irina"},{"full_name":"Liedtke, David Jan","id":"55557","last_name":"Liedtke","first_name":"David Jan"},{"last_name":"Scheideler","full_name":"Scheideler, Christian","id":"20792","first_name":"Christian"}],"date_updated":"2026-02-11T08:31:14Z","page":"325-342","citation":{"ama":"Kostitsyna I, Liedtke DJ, Scheideler C.

To maintain high accuracy when deviating from the established circular scan trajectory, trajectory calibration methods using multi-sphere reference objects with known marker positions are commonly employed. These multi-sphere objects can either be scanned together with the measurement object (online trajectory calibration) or in a separate scan (offline trajectory calibration). While offline calibration increases machine time, it generally results in higher scan quality. However, a sufficient pose repeatability is necessary to ensure comparable or even superior accuracy to online calibration. In this contribution, we present a straightforward procedure to compare both types of trajectory calibration in a way that the differences of the results can directly be traced back to the influence of the pose repeatability. The multi-sphere reference object is not only used for trajectory calibration, but simultaneously as a measurement object for repeated measurements. The methodology is tested on both a twin robotic CT system and a conventional CT system that is additionally equipped with a hexapod manipulator for adaptive object tilting. Results showed, independent from the type of trajectory calibration, systematic measurement errors in the order of 10−5–10−4 of measured sphere distances and sphericity values below 50 \r\n \r\n \r\n \r\n \r\n μ\r\n \r\n \r\n m\r\n \r\n \r\n \r\n . For sphere distances, random errors were increased by a factor of 5 due to the offline trajectory calibration, but were still low (\r\n \r\n \r\n \r\n \r\n <\r\n \r\n \r\n 1\r\n \r\n \r\n \r\n μ\r\n \r\n \r\n m\r\n \r\n \r\n \r\n ) in comparison to systematic errors and the spread of different measurement features. Overall, both investigated systems demonstrated sufficient positioning repeatability for offline trajectory calibration. The method is in general also applicable to any other types of manipulator systems used for CT devices. It provides a workflow for the decision which type of trajectory calibration is preferable for a given CT system.","lang":"eng"}],"publication":"Measurement Science and Technology","language":[{"iso":"eng"}]},{"status":"public","type":"conference_abstract","language":[{"iso":"eng"}],"_id":"64145","user_id":"77633","department":[{"_id":"300"}],"year":"2025","citation":{"chicago":"Newberry, Melissa, Gabriela Jonas-Ahrend, Meher Rizvi, and Anna van der Want. “The Dynamics of Geographic Space When Working with International Teacher Educators in Collaborative Research,” 2025.","ieee":"M.
