A quantum information processor with trapped ions

Understand

Quantum computers hold the promise to solve certain problems exponentially faster than their classical counterparts.

• Trapped atomic ions are among the physical systems in which building such a computing device seems viable.
• In this work we present a small-scale quantum information processor based on a string of $^{40}$Ca${^+}$ ions confined in a macroscopic linear Paul trap.
• We review our set of operations which includes non-coherent operations allowing us to realize arbitrary Markovian processes.
