Ok, so why does it help to go from the gigahertz area to low megahertz? Not sure what that is all about, why will it help the construction of Qubit computers? Are they talking about how long a Qubit can hang around so computation can be done?
Like how long it can remain stable and therefore useful?
If that is the gist, then the lower the frequency the longer it would be stable, like if that is the relationship, something running at say one Ghz would have a stable lifetime of one nanosecond, not terribly useful if that is what they are talking about.
