Realization of a quantum walk with one and two trapped ions
F. Zähringer, G. Kirchmair, R. Gerritsma +3
We experimentally demonstrate a quantum walk on a line in phase space using one and two trapped ion. A walk with up to 23 steps is realized by subjecting an ion to state-dependent…
Quantum simulation of the Dirac equation
R. Gerritsma, G. Kirchmair, F. Zähringer +3
The Dirac equation is a cornerstone in the history of physics, merging successfully quantum mechanics with special relativity, providing a natural description of the electron spin…
State-independent experimental test of quantum contextuality
G. Kirchmair, F. Zähringer, R. Gerritsma +5
The question of whether quantum phenomena can be explained by classical models with hidden variables is the subject of a long lasting debate. In 1964, Bell showed that certain type…
