Contribution & Novelties
The talk presents original research on constructing quantum error-correcting codes with enhanced transversal gate capabilities. The introduction of ‘phantom codes’ that allow arbitrary logical CNOT circuits via permutations is a novel contribution. The polynomial formalism provides a concise framework for analyzing transversal gates. The talk also offers a teleportation-based interpretation of transversal code switching, which may facilitate generalization to multi-logical-qubit codes.
