Poking Holes and Cutting Corners to Achieve Clifford Gates with the Surface Code

Error correction is essential to the development of practical quantum computers, but a leading method that relies on ``surface codes'' requires distinct and seemingly incompatible approaches to different computational operations. A new framework unifies these schemes and shows how to combine and compare different codes, an important tool for universal quantum computation.
