We investigate the extendibility problem for Brauer states, focusing on the symmetric two-sided extendibility and the de Finetti extendibility. By employing the representation theory of the unitary and orthogonal groups, we provide a general recipe for finding the (n, m)-extendible and n-de Finetti-extendible Brauer states. In the two-sided case we describe the special symmetry that only appears for (n, n)-extendible symmetric states. From the concrete form of the commutant to the diagonal action of the orthogonal group, we explicitly determine the set of parameters for which the Brauer states are (1, 2)-, (1, 3)- and (2, 2)-extendible in any dimension d. Using the branching rules from SU(d) to SO(d), we obtain the set of n-de Finetti-extendible Brauer states in low dimensions, and analytically describe the n → ∞ limiting shape for d = 3. Finally, we derive some general properties pertaining to the extendibility of Werner, isotropic and Brauer states. Copyright © 2024, The Authors. All rights reserved.

In this work, we generalize the Balasubramanian-Bax-Franklin-Glynn (BB/FG) permanent formula to account for row multiplicities during the permanent evaluation and reduce the complexity of permanent evaluation in scenarios where such multiplicities occur. This is achieved by incorporating n-ary Gray code ordering of the addends during the evaluation. We implemented the designed algorithm on FPGA-based data-flow engines and utilized the developed accessory to speed up boson sampling simulations up to 40 photons, by drawing samples from a 60 mode interferometer at an averaged rate of ∼ 80 seconds per sample utilizing 4 FPGA chips. We also show that the performance of our BS simulator is in line with the theoretical estimation of Clifford & Clifford [1] providing a way to define a single parameter to characterize the performance of the BS simulator in a portable way. The developed design can be used to simulate both ideal and lossy boson sampling experiments. © 2023, CC BY.

An overview of existing urban software mobile applications of the transport and economic direction is given. A model of a functional rationalizer of consumer behavior is being built. The software model of the functional rationalizer of consumer behavior (SM FRCB) was developed for the first time. PMFRCB allows the user to expand the number of his preferred needs (occupations, activities) during the daily cycle through intelligent recommendations. Also, SM FRCB allows you to optimize needs (activities, activities) at the cost and rate of their use. The SM FRCB is made in Python_3 using the libraries matplotlib, collections, numpy, pyplot, mplot3d. The analysis of consumer behavior before and after using the functional rationalizer model is carried out. The graphical results of a structural analysis of the costs of old and new consumer behavior, analysis of consumer behavior within the boundaries of the theory of possibilities and the model of transport behavior of a resident before and after applying the functional rationalizer model are presented. The prospects of further improving the SM FRCB are considered. © 2020 IEEE.

In the work intelligent system of a smart house is developed, which is designed to create from any house, office, or building a smart room. The best solutions and tools were chosen to develop the system, which allowed us to create a fast, optimized, reliable and easy-To-use system with a comfortable mobile and web-based user interface. The optimal parameters for deployment of the system (both hardware and software) were investigated and determined, and its operation in the planned mode, without any interruptions of the system operation. Upon completion of the design and development of the system, an analysis of the product was conducted, based on a control example, which made it possible to verify that the system was operating in accordance with the planned requirements, and provides access to all of the intended functionality. © 2019 IEEE.

The paper focuses on the role of version redundancy, which increases with the expansion of critical applications and the tightening of their functional safety requirements. International standards governing these requirements have already fixed the importance of version redundancy to counter common cause failures in safety-related systems. The problem of hidden faults inherent in these systems is equally acute, undermining confidence in the fault tolerance of circuit solutions important for functional safety. We suggest that this problem be seen as a growth problem where the system rises to the level of diversification in modes of operation by dividing them into normal and emergency and checkability circuits, but components continue to be stamped at a lower level of replication. Then the solution to the problem is to raise the components to the level of the system by developing their version redundancy. We demonstrate this development for FPGA components with LUT-oriented architecture and offer a method to improve the FPGA-ready project by natural version redundancy of its program code. The method generates a set of program code versions and selects versions that improve the checkability of circuits with respect to constant faults and the trustworthiness of results, respectively, in normal and emergency mode to reduce a set of hidden faults. The method is illustrated by an iterative array multiplier implemented in an FPGA project. Versions are generated, evaluated, and selected using the program developed for this.

Polynomial speedup in Torontonian calculation by a scalable recursive algorithm

arXiv 2021年

作者： Kaposi, Ágoston Kolarovszki, Zoltán Kozsik, Tamás Zimborás, Zoltán Rakyta, Péter Department of Programming Languages and Compilers Eötvös Loránd University Budapest Hungary Wigner Research Centre for Physics The Hungarian Academy of Sciences Budapest Hungary BME-MTA Lendület Quantum Information Theory Research Group Budapest Hungary Department of Physics of Complex Systems Eötvös Loránd University Budapest Hungary

Evaluating the Torontonian function is a central computational challenge in the simulation of Gaussian Boson Sampling (GBS) with threshold detection. In this work, we propose a recursive algorithm providing a polynomial speedup in the exact calculation of the Torontonian compared to state-of-the-art algorithms. According to our numerical analysis the complexity of the algorithm is proportional to N1.06912N/2 with N being the size of the problem. We also show that the recursive algorithm can be scaled up to HPC use cases making feasible the simulation of threshold GBS up to 35 − 40 photon clicks without the needs of large-scale computational capacities. © 2021, CC BY-SA.
