Efficient Magic State Cultivation on the Surface Code

Understand

Magic state cultivation is a leading approach for generating the resource states required for fault-tolerant quantum computation.

• Here we present a new cultivation protocol that increases the success probability of magic-state generation in platforms with flexible and non-local connectivity.
• Our method implements cultivation directly on the surface code, avoiding the detour through alternative, less efficient error-correcting codes used in prior approaches.
• This both improves the acceptance rate and preserves compatibility with the geometry of the code and the hardware.
