Passing barriers

In quantum physics the real trick is not the rebound of electrons like the rebound of droplets, but the passing of electrons of an insulating barrier. The experiment of the ”Josephson junction” has set a precedent to research the surprising macro-effect of “quantum tunnelling”. The 2025 Nobel Prize has been awarded to Clarke, Devoret and Martinis who observed these effects on a macroscopic scale. The applications in the most advanced quantum computers of today shows the enormous potential of this demonstration in pushing computing speed boundaries. The international competition to develop such, ever faster computers, based on quantum physics, is running on high development speed. In combination with the artificial intelligence (AI) developments, these types of combined machines are likely to outpace the development of human-based intelligence. It becomes even more important to define the limits for those machines by us. Subsequently, we shall have to make sure that such combined machines stick to the rules, we define(d).
