Didn't know Steve Blank was looking at quantum computing! That's cool.

I had a brief run-in with error-correcting gates. My research topic was about a simple bit-flip operation (quantum dot qubits) under random "telegraph" noise -- different laser pulse shapes result in different error rates which are actually a function of time (on the scale of the pulse itself). Point being that even given a particular physical qubit framework, individual gates are actually a family of (physical) operations with different error rates (and other features, of course) to be optimized for the same logical operation. Not too unlike the idea of NAND vs NOR flash.

Personally, I feel that's slightly "good" in the sense that there are many paths we can take to get quantum computation "good enough".
