qbits have 3 states
I thought it broke at a complexity of 128^3 from what was previously discussed last time...
Forbes and the financial Times seem really awful sources nowadays, ...
I do not understand clearly your point. For me it would be a question on how long would it take to break a key, so it would have to be measured in terms of the speed at which a key can be broken.
