Abstract
The color code has been invaluable for the development of the theory of fault-tolerant logic gates using transversal rotations. Three-dimensional examples of the color code have shown us how its structure, specifically the intersection of the supports of logical operators, can give rise to non-Clifford and gates. Here we present a color code with a logical control- gate that is accomplished with transversal and rotations on its physical qubits.
