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 DTSTAMP:20230609T134954Z END:VEVENT END:VCALENDAR
