Will logical clock cycle time be a limiting factor for quantum computations?

See the paper "time-optimal quantum computation" and "Flexible layout of surface code computations using AutoCCZ states". For Clifford operations, time is not a concern at all. ...

Why do Surface codes generate so much measurement data?

In a surface code, half the qubits are measurement qubits used to measure the stabilizers. In a superconducting chip you can run a surface code cycle, measuring all the stabilizers, in less than a ...
