Digital-Analog Quantum Simulation of Spin Models in Trapped Ions

Understand

We propose a method to simulate spin models in trapped ions using a digital-analog approach, consisting in a suitable gate decomposition in terms of analog blocks and digital steps.

• In this way, we show that the quantum dynamics of an enhanced variety of spin models could be implemented with substantially less number of gates than a fully digital approach.
• Typically, analog blocks are built of multipartite dynamics providing the complexity of the simulated model, while the digital steps are local operations bringing versatility to it.
• Finally, we describe a possible experimental implementation in trapped-ion technologies.
