Journal ArticleDOI
Quantum simulation of the Dirac equation
Rene Gerritsma,Rene Gerritsma,Gerhard Kirchmair,Gerhard Kirchmair,F. Zähringer,F. Zähringer,Enrique Solano,Enrique Solano,Rainer Blatt,Rainer Blatt,Christian F. Roos,Christian F. Roos +11 more
TL;DR: A proof-of-principle quantum simulation of the one-dimensional Dirac equation using a single trapped ion set to behave as a free relativistic quantum particle and study Zitterbewegung for different initial superpositions of positive- and negative-energy spinor states.
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
Realization of a quantum walk with one and two trapped ions.
F. Zähringer,F. Zähringer,Gerhard Kirchmair,Gerhard Kirchmair,Rene Gerritsma,Rene Gerritsma,Enrique Solano,Enrique Solano,Rainer Blatt,Rainer Blatt,Christian F. Roos,Christian F. Roos +11 more
TL;DR: This work experimentally demonstrates a quantum walk on a line in phase space using one and two trapped ions, and extends the quantum walk by using two ions, giving the walker the additional possibility to stay instead of taking a step.
Journal ArticleDOI
Quantum simulation of the Klein paradox with trapped ions.
Rene Gerritsma,Rene Gerritsma,B. P. Lanyon,B. P. Lanyon,Gerhard Kirchmair,Gerhard Kirchmair,F. Zähringer,F. Zähringer,Cornelius Hempel,Cornelius Hempel,Jorge Casanova,Juan José García-Ripoll,Enrique Solano,Enrique Solano,Rainer Blatt,Rainer Blatt,Christian F. Roos,Christian F. Roos +17 more
TL;DR: By precisely engineering a range of external potentials, this work is able to simulate text book relativistic scattering experiments and study Klein tunneling in an analogue quantum simulator and describe extensions to solve problems that are beyond current classical computing capabilities.
Journal ArticleDOI
Deterministic entanglement of ions in thermal states of motion
Gerhard Kirchmair,Gerhard Kirchmair,J. Benhelm,J. Benhelm,F. Zähringer,F. Zähringer,Rene Gerritsma,Rene Gerritsma,Christian F. Roos,Christian F. Roos,Rainer Blatt,Rainer Blatt +11 more
TL;DR: In this paper, the authors describe the implementation of a M?lmer?S?rensen gate entangling two 40Ca+ ions using a bichromatic laser beam near-resonant with a quadrupole transition.
