Exact first-detection probability in a locally monitored solvable quantum circuit
Cecilia De Fazio, Igor Lesanovsky, Gabriele Perfetto
We study the interplay between local stroboscopic measurements and the unitary quantum circuit dynamics of the deterministic Floquet-quantum East model. We derive exact analytical…
Collective Dynamics in Spin Chains with Constrained Dissipation: Classically Fragile but Quantum Robust
Pietro Brighi, Gianluca Frazzei, Igor Lesanovsky +2
Collective non-equilibrium phenomena in many-body systems are strongly influenced by fluctuations, particularly in the vicinity of phase transitions, where the interplay between cl…
Quantum Fisher Information of Driven-Dissipative Systems from Keldysh Path Integrals
Malik Jirasek, Igor Lesanovsky, Viktoria Noel
Driven-dissipative many-body quantum systems can be exploited in quantum enhanced sensing protocols. Here, non-classical correlations may allow one to reach a measurement precision…
Anomalously enhanced lifetimes of low angular momentum Rydberg states in singly charged alkaline-earth metal ions
Simon Euchner, Weibin Li, Igor Lesanovsky
Trapped ions excited to high-lying electronic states, so-called Rydberg states, open new opportunities for quantum simulation and quantum computing. Generally, the fidelity of quan…
The effects of shot noise on the quantum computation of NMR spectra
Sebastian Walch, Keith R. Fratus, Jan-Michael Reiner +1
Recent advances in the field of quantum computing hardware motivate the search for applications which demonstrate so-called quantum advantage. One promising use case that has been…
Detecting nonequilibrium phase transitions via continuous monitoring of space-time trajectories and autoencoder-based clustering
Erik Fitzner, Francesco Carnazza, Federico Carollo +1
The characterization of collective behavior and nonequilibrium phase transitions in quantum systems is typically rooted in the analysis of suitable system observables, so-called or…
