Quantum physics is the branch of science that studies the behavior of the particles that make up our Universe: electrons, photons, atoms, and other fundamental constituents of matter.
While classical physics allows us to understand the motion of everyday objects, it reaches its limits when observing the microscopic world. Quantum physics was born to explain these phenomena that seemed impossible to understand with the old theories.
At the quantum level, the rules are very different from those we observe every day. A particle can sometimes exist in multiple possibilities before a measurement is made. Scientists cannot always predict exactly what will happen, but can only calculate the probabilities of the different possible outcomes. This notion of probability is not related to a lack of information: it is an integral part of the functioning of nature itself.
One of the major discoveries of quantum physics is that some events are truly random. Unlike a roll of dice, whose outcome theoretically depends on measurable physical parameters, certain quantum phenomena cannot be predicted with certainty, even with all available information.
It is this principle that enables the creation of quantum random numbers (QRNG), used in the fields of computer security, encryption, and advanced technologies.
Even though it seems complex, quantum physics is omnipresent in our modern life. It is the origin of many technologies. Without quantum physics, a large part of today's digital world simply would not exist.
Quantum physics not only allows us to understand the deep structure of the Universe, but also to develop the technologies of tomorrow.
Many innovations are already based on the discoveries made in this field.
Quantum physics is the science that describes the behavior of the invisible world that makes up all matter. It reveals a Universe where probabilities, chance, and astonishing phenomena play an essential role.
Although it may seem mysterious, it is today one of the most reliable and useful scientific theories ever developed, at the heart of many technologies that shape our daily lives.
