More Flexible Entangling Gates Need to Earn Their Complexity
A unitary-synthesis toolset identifies when native trapped-ion multiqubit gates can outweigh the engineering cost of a broader gate set.
Summary
A unitary-synthesis toolset identifies when native trapped-ion multiqubit gates can outweigh the engineering cost of a broader gate set.
Trapped-ion machines can offer long coherence, broad connectivity and native multiqubit operations, but additional gate flexibility also raises control complexity. The researchers use unitary synthesis as an application-neutral benchmark and build a toolset for comparing gate sets composed of native Mølmer-Sørensen operations. Their analysis identifies hardware requirements under which multiqubit gates become advantageous. It is a comparative design study, not a demonstration of quantum advantage on a particular processor.
