Extracting conformal data from Loschmidt echoes after critical quenches

Aleix Bou-Comas, Stefano Carignano, Sergio Cerezo-Roquebrún +2

Conformal field theory provides universal predictions for Loschmidt amplitudes following quenches from product states to critical Hamiltonians. Building on this observation, we dev…

Reading Qubits with Sequential Weak Measurements: Limits of Information Extraction

Cesar Lema, Aleix Bou-Comas, Atithi Acharya +2

Quantum information processing and computation requires high accuracy qubit configuration readout. In many practical schemes, the initial qubit configuration has to be inferred fro…

Mesoscopic Regimes of Temporal Entanglement in Ergodic Quantum Systems

Sergio Cerezo-Roquebrún, Jan Thorben Schneider, Stefano Carignano +4

We study temporal correlations in interacting quantum systems through the influence functional of a half-infinite quantum Ising chain. Using Rényi entropies and temporal mutual in…

Measuring temporal entropies in experiments

Aleix Bou-Comas, Carlos Ramos Marimón, Jan T. Schneider +2

We propose a novel experimental protocol to measure generalized temporal entropies in many-body quantum systems. Our approach involves using local operators as probes to characteri…

Spatio-temporal tensor-network approaches to out-of-equilibrium dynamics bridging open and closed systems

Sergio Cerezo-Roquebrún, Aleix Bou-Comas, Jan T. Schneider +3

The study of many-body quantum systems out of equilibrium remains a significant challenge with complexity barriers arising in both state and operator-based representations. In this…
