Experimental Detection of Dissipative Quantum Chaos
Kristian Wold, Zitian Zhu, Feitong Jin +13
More than four decades of research on chaos in isolated quantum systems have led to the identification of universal signatures -- such as level repulsion and eigenstate thermalizat…
Quantum Liouvillian Tomography
Diogo Aguiar, Kristian Wold, Sergey Denisov +1
Characterization of near-term quantum computing platforms requires the ability to capture and quantify dissipative effects. This is an inherently challenging task, as these effects…
Spectral delineation of Markov Generators: Classical vs Quantum
Dariusz Chruściński, Sergey Denisov, Wojciech Tarnowski +1
The celebrated theorem of Perron and Frobenius implies that spectra of classical Markov operators, represented by stochastic matrices, are restricted to the unit disk. This propert…
Dissipation-Induced Threshold on Integrability Footprints
Rodrigo M. C. Pereira, Nadir Samos Sáenz de Buruaga, Kristian Wold +4
The presence of a dissipative environment substantially disrupts unitary evolution. Nevertheless, key features of the evolution, such as its integrable or chaotic nature, are not i…
