Seminar

Quantum software shifting from theory to practice and education

Speaker
Abuzer Yakaryilmaz, University of Latvia
Date
Abstract

In this talk, we shortly introduce the emerging field quantum software (quantum programming and quantum machine learning), and then we discuss how we can be involved and then shape the field. We explain why education is our primary focus and how we can use pedagogical tools to attract new generation and people to the field. We share our own experiences, our ongoing projects, and also our upcoming projects. At the end, we discuss possible collaborations.

Seminar

Utilizing Quadratic Unconstrained Binary Optimization problem for simulating dynamics of quantum system

Speaker

Abstract

We introduce a novel approach to simulate dynamical (linear) systems (quantum or otherwise) parallel in time using quantum annealers. In particular,  we describe how the solution state vector can be found by solving a specifically crafted system of linear equations. Moreover, we demonstrate that such systems can, in fact, be effectively solved (up to a given precision) with Quadratic Unconstrained Binary Optimization. This naturally leads to a class of hybrid classical-quantum algorithms that can be implemented and executed on near-term quantum annealers.

Seminar

Algorithms for simultaneous unicast and anycast flows and capacity in multilayer networks

Speaker

Date
Abstract

In this presentation I am goin to show models, algorithms and computational results of CFA (Capacity and Flow Assignment) problem in multi-layer networks. The idea of multilayer, based on MPLS over DWDM architecture, is as follows. The logical links given by paths allocated to demands of the upper layer are constructed using light-paths of the lower layer. In the upper layer we introduce two kinds of traffics: uni-cast (one-to-one) and any cast (one-to-one-of-many).

Seminar

Hierarchical correlation reconstruction - between statistics and ML

Speaker
Jarosław Duda, Wydział Matematyki i Informatyki, Uniwersytet Jagielloński
Date
Abstract
While machine learning techniques are very powerful, they have some weaknesses, like iterative optimization with many local minimums, large freedom of parameters, lack of their interpretability and accuracy control. From the other side we have classical statistics based on moments not having these issues, but providing only a rough description. I will talk about approach which combines their advantages: with MSE-optimal moment-like coefficients, but designed such that we can directly translate them into probability density.
