Leveraging Zero-Level Distillation to Generate High-Fidelity Magic States

Understand

Magic state distillation plays an important role in universal fault-tolerant quantum computing, and its overhead is one of the major obstacles to realizing fault-tolerant quantum computers.

• Hence, many studies have been conducted to reduce this overhead.
• Among these, Litinski has provided a concrete assessment of resource-efficient distillation protocol implementations on the rotated surface code.
• On the other hand, recently, Itogawa et al.
