WP 2

Trapped ions

The digital processing WP aims to explore topological phenomena using the unique capabilities of trapped ion experiments.

This will be achieved through close collaboration with theory and analogue processing nodes to provide complementary insight into the common overall goal of this project.

While the digital approach may have a more challenging time generating real-time dynamics, it is more flexible in constructing Hamiltonians and dynamics, as well as arbitrary perturbations for studying out-of-equilibrium physics.

In particular, the digital approach will allow us to make connections and exploit the concepts and tools of quantum information theory, including the study of quantities such as entanglement spectra and topological invariants.

Tasks

The implementation of new protocols for quantum simulation of quantum states of matter with trapped ions (M1–M24; responsible: UIBK; involved: UPV/EHU, IJS)

Our goal is to demonstrate unprecedented experimental observation of topological effects in integer-spin Heisenberg chains and investigate whether robust quantum information processing could be facilitated by symmetry-protected holonomic quantum gates.

Building upon the results from WP1, we will characterize the mains sources of noise in our quantum simulators and validate the performance of our devices by using newly developed TN approaches.

Using the digital quantum simulator, we will exploit quantum information tools, including the entanglement spectrum, to characterize the Haldane phase in detail and study its resistance to perturbations closely related to WP1.
