SurfBraid: A concept tool for preparing and resource estimating quantum circuits protected by the surface code

Understand

The first generations of quantum computers will execute fault-tolerant quantum circuits, and it is very likely that such circuits will use surface quantum error correcting codes.

• To the best of our knowledge, no complete design automation tool for such circuits is currently available.
• This is to a large extent because such circuits have three dimensional layouts (e.g.
• two dimensional hardware and time axis as a third dimension) and their optimisation is still ongoing research.
