Speaker:Andrzej Wodecki, Uniwersytet Marii Curie-Skłodowskiej w LublinieIn past years we witness the flourishing of artificial intelligence, both in methods and in various applications. This is largely due to the ever-increasing availability of essential tools (software, infrastructure), knowledge, and growing interest in the industry more and more willing to invest in such solutions.

The quantum entanglement is considered as one of the most important notions of quantum computing. The entanglement is a feature of quantum systems and it is used as a basis for many quantum algorithms and protocols. In this presentation we analyze the level of entanglement for the quantum switch, during its work. The level of entanglement during the correct operating may be compared with the situation when a noise is present in the analyzed system. The noise changes the level of quantum entanglement and we utilize this observation to evaluate if the switch works properly.

We present a link between the combinatorial notion of orthogonal arrays and k-uniform states, i.e., multipartite pure states such that every reduction to k parties is maximally mixed. As consequence, simple constructions of 1 and 2 uniform states for homogeneous (N qudits) and heterogeneous systems (e.g. N qubits + M qutrits) are derived.

Classical methods for processing and analysis of multidimensional signals – such as color videos and hyperspectral images – do not exploit full information contained in inner their factors. On the other hand, recently developed tensor based methods allow for data representation and analysis which directly account for data multidimensionality. Examples can be found in many applications such as face recognition, image synthesis, video analysis, surveillance systems, sensor networks, data stream analysis, marketing and medical data analysis, to name a few.

In this presentation, I will discuss a number of issues related to the problem of selecting a group of candidates (referred to as the committee). Committee elections have applications ranging from shortlisting, through the issue of finding items to present on a store's website, to parliamentary elections (or, on a smaller scale, the problem of choosing the electors at a university). I will show simulation results for a number of multiwinner rules and discuss these rules' computational complexity and axiomatic properties.

During the presentation I will introduce the formalism of tensor networks and introduce their relevance to describe the basic states of many-body systems. Then I will introduce the simplest model with topological order presented by Alexei Kitaev, known as the toric code. On his example, I will construct a Projected Entangled Pair States (PEPS) tensor network that describes the basic state of the model and will present the purpose of my project, ie, investigating anion excitation statistics.
