Guys, to all those who are attempting a replication please take note.
Fuzzy has just done a test on a resistor that closely approximates our quantum test resistor. He took the frequency down to 70 Khz and the sad news is that the advantage was completely lost. Please, therefore, do not get married to the quantum frequency. Test a range of this and the chances are that you will need to run at a higher frequency and possibly also a higher duty cycle. The assumption is that your 555 switching arrangement are in line with Fuzzy's and Aaron's before him.
I suspect that the best guide here will be to let the circuit find it's own preferred oscillation. Component variations seem to result in HUGE variations in frequency. So sorry to introduce yet another variable.
