DESCRIPTION:Summary \n\nGRAPHICAL CSS CODE TRANSFORMATION USING ZX CALCULUS
 \n\nAbstract: In this work\, we present a generic approach to transform CS
 S\ncodes by building upon their equivalence to phase-free ZX diagrams.\nUs
 ing the ZX calculus\, we demonstrate diagrammatic transformations\nbetween
  encoding maps associated with different codes. As a motivating\nexample\,
  we give explicit transformations between the Steane code and\nthe quantum
  Reed-Muller code\, since by switching between these two\ncodes\, one can 
 obtain a fault-tolerant universal gate set. To this\nend\, we propose a bi
 directional rewrite rule to find a (not\nnecessarily transversal) physical
  implementation for any logical ZX\ndiagram in any CSS code. \n\nThen we f
 ocus on two code transformation techniques: code morphing\, a\nprocedure t
 hat transforms a code while retaining its fault-tolerant\ngates\, and gaug
 e fixing\, where complimentary codes (such as the Steane\nand quantum Reed
 -Muller codes) can be obtained from a common subsystem\ncode. We provide e
 xplicit graphical derivations for these techniques\nand show how ZX and gr
 aphical encoder maps relate several equivalent\nperspectives on these code
  transforming operations.\n
