Journal ArticleDOI
Direct Observation of Dynamical Quantum Phase Transitions in an Interacting Many-Body System
Petar Jurcevic,Petar Jurcevic,Heng Shen,Philipp Hauke,Christine Maier,Christine Maier,Tiff Brydges,Tiff Brydges,Cornelius Hempel,B. P. Lanyon,B. P. Lanyon,Markus Heyl,Markus Heyl,Rainer Blatt,Rainer Blatt,Christian F. Roos,Christian F. Roos +16 more
TL;DR: This work investigates and measures dynamical quantum phase transitions in a string of ions simulating interacting transverse-field Ising models, and establishes a link between DQPTs and the dynamics of other quantities such as the magnetization.
Journal ArticleDOI
Self-verifying variational quantum simulation of lattice models
Christian Kokail,Christian Kokail,Christine Maier,Christine Maier,R. M. W. van Bijnen,R. M. W. van Bijnen,Tiff Brydges,Tiff Brydges,M. K. Joshi,M. K. Joshi,Petar Jurcevic,Petar Jurcevic,Christine A. Muschik,Christine A. Muschik,Pietro Silvi,Pietro Silvi,Rainer Blatt,Rainer Blatt,Christian F. Roos,Christian F. Roos,Peter Zoller,Peter Zoller +21 more
TL;DR: Experiments are presented that demonstrate self-verifying, hybrid, variational quantum simulation of lattice models in condensed matter and high-energy physics, enabling the study of a wide variety of previously intractable target models.
Journal ArticleDOI
Probing Rényi entanglement entropy via randomized measurements.
Tiff Brydges,Tiff Brydges,Andreas Elben,Andreas Elben,Petar Jurcevic,Petar Jurcevic,Benoît Vermersch,Benoît Vermersch,Christine Maier,Christine Maier,B. P. Lanyon,B. P. Lanyon,Peter Zoller,Peter Zoller,Rainer Blatt,Rainer Blatt,Christian F. Roos,Christian F. Roos +17 more
TL;DR: Here, a protocol for measuring the second-order Rényi entropy based on statistical correlations between randomized measurements is presented and experimentally demonstrated, representing a universal tool for probing and characterizing engineered quantum systems in the laboratory.
Journal ArticleDOI
Self-Verifying Variational Quantum Simulation of the Lattice Schwinger Model
Christian Kokail,Christine Maier,Rick van Bijnen,Tiff Brydges,M. K. Joshi,Petar Jurcevic,Christine A. Muschik,Pietro Silvi,Rainer Blatt,Christian F. Roos,Peter Zoller +10 more
TL;DR: In this article, a self-verifying, hybrid, variational quantum simulation of lattice models in condensed matter and high-energy physics is presented, where the quantum co-processor is a programmable, trapped-ion analog quantum simulator with up to 20 qubits.
Journal ArticleDOI
Probing entanglement entropy via randomized measurements
Tiff Brydges,Andreas Elben,Petar Jurcevic,Benoît Vermersch,Christine Maier,B. P. Lanyon,Peter Zoller,Rainer Blatt,Christian F. Roos +8 more
TL;DR: In this article, a new protocol for measuring entropy, based on statistical correlations between randomized measurements, is presented and experimentally demonstrated for probing and characterizing engineered quantum systems in the laboratory, applicable to arbitrary quantum states of up to several tens of qubits.
