You're repeating nonsensical marketspeak. What does "a number that didn't exist before ..." even mean? And what does "quantum measurement principles" mean? I'll tell you: it means diddly squat.
The device the article is about measures electron flow through an electronic component through which 'usually' no electrons flow. That electrons flow in this device, is because they tunnel through the potential barrier. That's a quantum effect if there ever was one.
Converting the presence of electron flow into a number means you construct these numbers on the fly. The numbers did not 'exist before', for any reasonable meaning of that term.
