Distillation tile layouts and scheduling within a magic state factory for magic state distillation techniques

Abstract

Techniques for optimizing distillation tile layouts for distillation tiles in a magic state factory of a quantum computer and a scheduling of distilled magic state production (e.g., using temporally encoded lattice surgery based (TELS-based) magic state distillation) using said distillation tiles are disclosed. Customized designs for distillation tile layouts that reduce space-time costs when executing a given quantum algorithm are presented, wherein the designs may be customized based, at least in part, on a selected classical error-correcting code and distillation circuit, on a decision whether to perform parallelized TELS-based magic state distillation, etc. Production of distilled magic states may then be configured using a round robin scheduling design in order to minimize potential time in which a processing core of the quantum computer is waiting for another newly distilled magic state from the magic state factory to use for logical computation related to the given quantum algorithm being executed.
