Speaker: Sophia Denker (University of Siegen) Abstract Verifying entanglement between parties is essential for creating a secure quantum network, and Bell tests are the most rigorous method for doing so. However, if there is any signalling between the parties, then the violation of these inequalities can no longer be used to draw conclusions about the presence […]

Speaker: Michał Oszmaniec (University of Warsaw) Abstract In quantum theory general measurements are described by so-called Positive Operator-Valued Measures (POVMs). In this work we show that in d-dimensional quantum systems an application of depolarizing noise with constant (independent of d) visibility parameter makes any POVM simulable by a randomized implementation of projective measurements that do […]

Speaker: Julian Siegl Abstract The combined action of a DC bias and a microwave drive on the transport characteristic of a superconductor-quantum dot-superconductor junction is investigated. To cope with time dependent non-equilibrium effects and interactions in the quantum dot, we develop a general formalism for the dynamics of the density operator based on a particle […]

Speaker: Tony Apollaro (University of Malta) Abstract The transfer of quantum information between different locations is key to many quantum information processing tasks. Whereas, the transfer of a single qubit state has been extensively investigated, the transfer of a many-body system configuration has insofar remained elusive. We address the problem of transferring the state of […]

Speaker:  Janek Kozicki (Gdańsk University of Technology) Abstract In this talk I present a high-precision (15, 18 or 33 decimal places) C++ implementation of quantum dynamics time propagation algorithms for both time-independent and time-dependent Hamiltonian with an inhomogeneous source term. Moreover I present an extension of both algorithms for time propagation to handle arbitrary number […]

Speaker: Alexssandre de Oliveira Junior  (Faculty of Physics, UJ) Abstract Catalysis plays a key role in many scientific areas, most notably in chemistry and biology. In this talk, I will present a catalytic process in a paradigmatic quantum optics setup, namely the Jaynes-Cummings model, where an atom interacts with an optical cavity. The atom plays […]

Speaker: Fabio Costa (University of Queensland) Abstract What does it mean for a causal structure to be “unknown”? Can we even talk about “repetitions” of an experiment without prior knowledge of causal relations? And under what conditions can we say that a set of processes are independent and identically distributed (i.i.d.)? Similar questions for classical […]

Speaker: Ismael Delgado Gaspar (National Centre for Nuclear Research) Abstract The current era of precision cosmology has provided us with high-quality observational data across astrophysical and cosmological scales. Interpreting these data requires robust modeling of self-gravitating systems. However, the use of exact solutions of Einstein's equations and non-linear approaches has been less favored in examining […]
