Assembling a Quantum Processor

In the video, professor DiCarlo talks about three examples of surface codes, surface-7, surface-17, surface-49. What do the number ‘7’, ‘17’, and ‘49’ represent? What are these surface codes able to correct?

These numbers represent the number of physical qubits needed to work with each surface code. For example, the surface-7 code needs 7 physical qubits to work.

Surface codes aim to detect and correct arbitrary single qubit errors.
