error correction after lattice surgery for merging

are we doing error correction before or after applying CNOT gate The error correction is not time sensitive so this doesn't matter. You can do it after. You can even do it a hundred surface code ...

Confusion about lattice-surgery operation

According to https://arxiv.org/abs/1111.4022, to perform a logical CNOT using lattice surgery, three patches of surface codes are needed They show that three patches are sufficient, not that three ...

How does the surface code satisfy constraints of relativity?

TL;DR: Yes, you can apply logical $X$ gate by applying physical $X$ gate on qubits along one boundary, e.g. on the left, and you can measure logical $X$ by measuring physical $X$ on qubits along ...
