Trotterisation Thresholds and Dissipative Quantum Chaos in Open-System Digital Quantum Simulation
Angsar Manatuly, Lukas M. Sieberer, Cahit Kargi +1
Digital quantum simulation (DQS) is one of the most promising applications of quantum computing. Trotterised DQS models quantum dynamics by decomposing the evolution into a sequenc…
Replica Keldysh field theory of quantum-jump processes: General formalism and application to imbalanced and inefficient fermion counting
Felix Kloiber-Tollinger, Lukas M. Sieberer
Measurement-induced phase transitions have largely been explored for projective or continuous measurements of Hermitian observables, assuming perfect detection without information…
Absence of measurement- and unraveling-induced entanglement transitions in continuously monitored one-dimensional free fermions
Clemens Niederegger, Tatiana Vovk, Elias Starchl +1
Continuous monitoring of one-dimensional free fermionic systems can generate phenomena reminiscent of quantum criticality, such as logarithmic entanglement growth, algebraic correl…
Noise resilience of two-dimensional Floquet topological phases
Balaganchi A. Bhargava, Sanjib Kumar Das, Lukas M. Sieberer +1
We study the effect of noise on two-dimensional periodically driven topological phases, focusing on two examples: the anomalous Floquet-Anderson phase and the disordered Floquet-Ch…
Generalized Zeno effect and entanglement dynamics induced by fermion counting
Elias Starchl, Mark H. Fischer, Lukas M. Sieberer
We study a one-dimensional lattice system of free fermions subjected to a generalized measurement process: the system exchanges particles with its environment, but each fermion lea…
Universality in driven open quantum matter
Lukas M. Sieberer, Michael Buchhold, Jamir Marino +1
Universality is a powerful concept, which enables making qualitative and quantitative predictions in systems with extensively many degrees of freedom. It finds realizations in almo…
