Entanglement generation in a two-body Schrödinger--Newton model
Marcin Płodzień, Julia Osęka-Lenart, Maciej Lewenstein +1
The Schrödinger--Newton (SN) equation provides a semiclassical framework for the evolution of self-gravitating of massive quantum systems. We propose a two-body Schrödinger--Newton…
Operator spreading and recoverability of local quantum Fisher information in a -broken spin chain
Marcin Płodzień, Jan Chwedeńczuk
While out-of-time-order correlators establish a causal light cone for operator spreading, they do not guarantee that the parameter sensitivity carried by the operator remains local…
Quantum Scrambling Born Machine
Marcin Płodzień
Quantum generative modeling, where the Born rule naturally defines probability distributions through measurement of parameterized quantum states, is a promising near-term applicati…
Neural quantum states for entanglement depth certification from randomized Pauli measurements
Marcin Płodzień
Entanglement depth quantifies how many qubits share genuine multipartite entanglement, but certification typically relies on tailored witnesses or full tomography, both of which sc…
Lecture Notes on Information Scrambling, Quantum Chaos, and Haar-Random States
Marcin Płodzień
Information scrambling, the process by which quantum information spreads and becomes effectively inaccessible, is central to modern quantum statistical physics and quantum chaos. T…
