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.

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).
We conduct experimental simulations of many-body quantum systems using a hybrid classical-quantum algorithm. In our setup, the wave function of the transverse field quantum Ising model is represented by a restricted Boltzmann machine.
The Foundation for Polish Science announced the results of the first TEAM-NET competition. Co-financing for the total amount of nearly PLN 18 million was received by the consortium CFT, IITiS, UJ.
A new method for constructing a digital water-marking based on the Ateb-functions is proposed. This new approach belongs to methods of protecting images based on hiding data in the frequency domain. It is a generalization the well-known method using Fourier transform. The proposed method, based on the two dimension Discrete Ateb Transform is resistant to most types of attacks. Our experiments prove its efficiency and stability.
