The post-Cold War period, which began with the demise of the Soviet Union and characterized by unchallenged American supremacy, has come to an end a few years ago, although the perception of this change of epoch is only beginning to be admitted by global political authorities. A new era, which we cannot yet name, has arrived gradually, and is characterized by the significant increase in the technological ambitions of the great world powers, and in particular by the acceleration of technological programs linked to La Défense.
Whether or not it is a new arms race, the fact is that in just a few years, several technologies have established themselves at the heart of the military technological ambitions of these countries, taking over in the background some others presented as revolutionary. just a few months ago, like stealth. What are these new technologies that are revolutionizing, or will revolutionize in the coming years, military action, as well as the technological hierarchy of Nations, on a global scale?
1- Applications of Quantum Mechanics
Niels Bohr, the father of modern physics, used to say that if quantum physics hasn't shocked you deeply, you haven't understood it. No need therefore, in a paragraph, to try to explain the foundations and principles that define it. On the other hand, it is useful to dwell on the very concrete applications of advances in this field, to design defense technologies. Several programs are directly linked to this “strange” and very promising physics.
Thus, several countries have undertaken to develop quantum computers, which by using the quantum state of matter, can transform a bit, which can take 2 forms (0 or 1), into a quBit, which can take up to 4 forms. , opening a new stage in the development of digital tools, with increased power at constant energy consumption vis-à-vis current processors. This revival of computing power in an energetically constrained environment obviously finds its place in modern weaponry, which is increasingly digitized, and gradually incorporating more and more on-board intelligence and processing capacities.
