Thanks for sharing that paper. Admittedly, that reply was typed on break and I debated about dragging you into it, #SimpleX
The only reason I ultimately decided to was that #SimpleX was the first quantam-whatever app I installed. Tuta was the second. In the case of both of you, #quantumcomputing was not yet a reality, so I just read it as one meaningless feature in a sea of others.
I prolly should have gone back & checked if you were guilty of the same sin. My apologies.
