Einleitung
[nur Englisch]
Scaling experimental quantum simulations based on ions might allow addressing intriguing quantum effects in many different fields of physics. Three ions residing in three individual traps are suited to simulate anti-ferromagnetic interactions between three quantum spins. This leads to puzzling effects already within this basic triangular configuration. Classically, only two neighboring spins can be orientated in an anti-ferromagnetic manner. The third spin cannot satisfy both neighbors, and hence, "becomes frustrated". Quantum mechanically, a superposition of all frustrated permutations, an entangled state, arises "naturally", leaving the individual spins undetermined while maximizing their correlations. In the envisioned, two-dimensional array of individually trapped ions, the whole quantum ensemble of spins evolves adiabatically, via a quantum-phase-transition into a tremendously complex, entangled state. The frustration in triangular spin lattices, for example, is suspected to be responsible for high Tc superconductivity and may remain unaccessible by classical approaches. |
