"This means, simply, that if a qubit starts in a “1” state, it will eventually emit a photon and fall to a “0” state...
Dr Carvalho’s solution is two-fold: first, to add noise (as photons, using a laser) back into a qubit before the state-decay takes place..."
So, essentially, in this way qubits act similarly to DRAM, requiring a refresh (as opposed to NVRAM). That's probably simplifying a bit, but I'd hope it's a good analogy for this crowd.
Of course, the mechanism to do this refresh, and the second part about the added noise essentially keeping the quantum uncertainty alive is well beyond my mortal ken...
