METHOD FOR MOVING MAGIC STATES THROUGH BOUNDARY EXTENSION IN ROTATED SURFACE CODE

Abstract: disclosed herein is a method for moving magic states through boundary extension in a rotated surface code. the method for moving magic states includes identifying logical data and an ancilla qubit constituting a logical qubit block, and an available magic state logical qubit from a magic state storage space, identifying a type of a movement operation and a bending location during movement by analyzing a path through which the magic state logical qubit is moved to a location of a desired logical ancilla qubit, defining a movement operation process based on boundary extension in consideration of the type of the movement operation and the bending location during the movement, and moving the magic state logical qubit to the location of the logical ancilla qubit in conformity with the movement operation process.
