Quantum analogues of exponential sensitivity: from Loschmidt echo to Krylov complexity
Ignacio GarcÃa-Mata, Diego A. Wisniacki
One of the fundamental manifestations of classical chaos is exponential sensitivity to initial conditions that is, two trajectories starting from nearly identical initial states di…
Fundamental Limits to Cat-Code Qubits from Chaos-Assisted Tunneling
Lionel E. MartÃnez, Ignacio GarcÃa-Mata, Diego A. Wisniacki
We show that chaos-assisted tunneling (CAT) imposes an intrinsic limit to the protection of Kerr-cat qubits. In the static effective description, tunneling between the quasidegener…
Quantum-to-classical correspondence in Krylov complexity
Gastón F. Scialchi, Gastón F. Scialchi, Augusto J. Roncaglia +1
We study quantum-to-classical correspondence of the Krylov space for evolutions driven by unitary maps with a classical limit. This entails a proper definition of corresponding qua…
Ruelle-Pollicott Decay of Out-of-Time-Order Correlators in Many-Body Systems
Jerónimo Duarte, Ignacio GarcÃa-Mata, Diego A. Wisniacki
The out-of-time-order correlator (OTOC) quantifies information scrambling in quantum systems and serves as a key diagnostic of quantum chaos. In one-body systems with a classical c…
Resonance Assisted Tunneling in Floquet spin-J systems
J. A. Segura-Landa, Diego A. Wisniacki, Sergio Lerma-Hernández +1
We apply the theory of Resonance Assisted Tunneling (RAT) to a many-body quantum kicked system with a well-defined semiclassical limit. Using a quantum resonant condition, we ident…
Impact of chaos on the excited-state quantum phase transition of the Kerr parametric oscillator
Ignacio GarcÃa-Mata, Miguel A. Prado Reynoso, Rodrigo G. Cortiñas +4
The driven Kerr parametric oscillator, of interest to fundamental physics and quantum technologies, exhibits an excited state quantum phase transition (ESQPT) originating in an uns…
