Visualizing quantum mechanics in an interactive simulation -- Virtual Lab by Quantum Flytrap
Piotr Migdał, Klementyna Jankiewicz, Paweł Grabarz +2
Virtual Lab by Quantum Flytrap explores novel ways to represent quantum phenomena interactively and intuitively. It is a no-code online laboratory with a real-time simulation of an…
Symmetries and self-similarity of many-body wavefunctions
Piotr Migdał
This PhD thesis is dedicated to the study of the interplay between symmetries of quantum states and their self-similar properties. It consists of three connected threads of researc…
Which multiphoton states are related via linear optics?
Piotr Migdał, Javier Rodríguez-Laguna, Michał Oszmaniec +1
We investigate which pure states of photons in modes can be transformed into each other via linear optics, without post-selection. In other words, we study the local unitar…
Community Detection in Quantum Complex Networks
Mauro Faccin, Piotr Migdał, Tomi H. Johnson +2
Determining community structure is a central topic in the study of complex networks, be it technological, social, biological or chemical, in static or interacting systems. In this…
Degree Distribution in Quantum Walks on Complex Networks
Mauro Faccin, Tomi Johnson, Jacob Biamonte +2
In this theoretical study, we analyze quantum walks on complex networks, which model network-based processes ranging from quantum computing to biology and even sociology. Specifica…
Entanglement classes of permutation-symmetric qudit states: symmetric operations suffice
Piotr Migdał, Javier Rodriguez-Laguna, Maciej Lewenstein
We analyse entanglement classes for permutation-symmetric states for n qudits (i.e. d-level systems), with respect to local unitary operations (LU-equivalence) and stochastic local…
Qubism: self-similar visualization of many-body wavefunctions
Javier Rodriguez-Laguna, Piotr Migdał, Miguel Ibáñez Berganza +2
A visualization scheme for quantum many-body wavefunctions is described, which we have termed qubism. Its main property is its recursivity: increasing the number of qubits reflects…
Immunity of information encoded in decoherence-free subspaces to particle loss
Piotr Migdał, Konrad Banaszek
We demonstrate that for an ensemble of qudits, subjected to collective decoherence in the form of perfectly correlated random SU(d) unitaries, quantum superpositions stored in the…
Quantum and semiclassical polarization correlations
Konrad Banaszek, Rafal Demkowicz-Dobrzanski, Michal Karpinski +2
We analyze the strength of polarization correlations between two light beams that can be achieved in the semiclassical regime using statistical mixtures of coherent states and bina…
