Translating measurement-based quantum computation with gflow into quantum circuit

Abstract (in Japanese) (See Japanese page) 
(in English) Flow and gflow are ordering relations on a graph that guarantee deterministic implementations of a unitary by measurement-based quantum computation (MBQC). There is a method called the star pattern transformation to derive a circuit decomposition of a unitary described by MBQC on a graph with flow. The straightforward extension of this method applied to graphs with gflow, however, leads to a crcuit including acausal gates, which is not well-defined in the quantum circuit model. In this work, we present a generalized method to translate any unitary implemented by MBQC with gflow into a quantum circuit without dealing with acausal gates. We also present another translation method that first maps to a quantum circuit including acausal gates and then transforms it to a well-defined quantum circuit by canceling the acausal gates. By comparing these two methods, we study how depth of quantum computation can be compressed in MBQC comparing to the quantum circuit model.
