Dissipative Landau-Zener tunneling in the crossover regime from weak to strong environment coupling
X. Dai, R. Trappen, H. Chen +22
Landau-Zener tunneling, which describes the transition in a two-level system during a sweep through an anti-crossing, is a model applicable to a wide range of physical phenomena. R…

Applications and resource estimates for open system simulation on a quantum computer
Evgeny Mozgunov, Jeffrey Marshall, Namit Anand
We present two applications where open system quantum simulation is the preferred approach on a quantum computer. We choose concrete parameters for the problems in such a way that…

Detecting Quantum and Classical Phase Transitions via Unsupervised Machine Learning of the Fisher Information Metric
Victor Kasatkin, Evgeny Mozgunov, Nicholas Ezzell +1
The detection of quantum and classical phase transitions in the absence of an order parameter is possible using the Fisher information metric (FIM), also known as fidelity suscepti…
