Journal ArticleDOI
Quasiparticle engineering and entanglement propagation in a quantum many-body system
Petar Jurcevic,B. P. Lanyon,Philipp Hauke,Cornelius Hempel,Peter Zoller,Rainer Blatt,Christian F. Roos +6 more
TL;DR: First, the entanglement distributed by quasiparticles as they trace out light-cone-like wavefronts is observed, and second, using the ability to tune the interaction range in the system, information propagation is observed in an experimental regime where the effective-light-cone picture does not apply.
Journal ArticleDOI
Universal Digital Quantum Simulation with Trapped Ions
B. P. Lanyon,B. P. Lanyon,Cornelius Hempel,Cornelius Hempel,Daniel Nigg,Markus Müller,Markus Müller,Rene Gerritsma,Rene Gerritsma,F. Zähringer,F. Zähringer,Philipp Schindler,Julio T. Barreiro,Markus Rambach,Markus Rambach,Gerhard Kirchmair,Gerhard Kirchmair,Markus Hennrich,Peter Zoller,Peter Zoller,Rainer Blatt,Rainer Blatt,Christian F. Roos,Christian F. Roos +23 more
TL;DR: The digital approach to quantum simulation in a system of trapped ions is demonstrated and evidence that the level of control required for a full-scale device is within reach is provided.
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
Quantum Chemistry Calculations on a Trapped-Ion Quantum Simulator
Cornelius Hempel,Cornelius Hempel,Christine Maier,Christine Maier,Jonathan Romero,Jarrod R. McClean,Thomas Monz,Heng Shen,Heng Shen,Petar Jurcevic,Petar Jurcevic,B. P. Lanyon,B. P. Lanyon,Peter J. Love,Ryan Babbush,Alán Aspuru-Guzik,Rainer Blatt,Rainer Blatt,Christian F. Roos,Christian F. Roos +19 more
TL;DR: In this article, a trapped-ion implementation of one such hybrid algorithm is used to solve a quantum chemistry problem, which is a promising approach for near-term practical applications of quantum computers.
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.
