YOZONE: Schrödinger on the beach – quantum physics in a deck chair

The superimposition of possibilities. A dead and alive cat at the same time. The ability to instantaneously act on a particle tens of thousands of kilometers away, that is, to transmit information faster than the speed of light allows. A story of Lewis Carroll ? A work of science fiction Gregory Egg Where Ted Chiang ? The delirium of a drifting mind? Nothing of the same. It’s real, it’s science, and it’s more surprising than the news of the day. For those who have never dealt with quantum physics, it is better to read ” Schrödinger on the beach – quantum physics in a deck chair comfortably and carefully installed in a deck chair, afraid of falling to the ground.

The reader will also be able to buckle up in his lounger, because quantum physics is different from the beach novel. By recalling the premises of the birth of quantum theory, the author confronts us with almost a century of history of physics. But it is above all the story of a conceptual earthquake that began in the first decades of the twentieth century, but whose non-scientists, through the multiplication of articles dedicated to popular magazines or the press for the general public, gradually begin to take the measure.

There are two reasons for this: on the one hand, we are beginning to know what are the phenomena that require quantum processes (so in the objects we deal with every day, we make quanta without knowing it, even in our own organic processes). , on the other hand, the multiplication of experiments that not only confirmed the theoretical points, but also opened the door to the manufacture of objects that invoke quantum physics, objects of which perhaps the most remarkable examples today are the first quantum computers.

A conceptual earthquake, then: because the discovery of a new world, essentially microscopic, where nothing happens intuitively and where the seemingly impossible happens, is accompanied by the highlighting of the porosity of the border between this world and ours. This conceptual earthquake is that of overlaying possibilities, where two opposing events coexist simultaneously. A world in which to use the formula Pascal“The opposite of one deep truth is another deep truth.” A world in which to use the famous image Schrodinger, a cat is dead and alive at the same time. The quantum world is that of “intrinsic randomness,” where nothing is certain, but everything lies within a range of perfectly described probabilities.

If God doesn’t roll the dice to use the famous formulaEinstein, in any case he seems to enjoy the multidimensional pool game of particles and their hard-to-imagine connections. It plays with our nerves, more precisely with our neurons, which like to tie knots when it comes to understanding how all this can work well and how the transition from the quantum world to that of classical physics can be managed. .

So it’s about exploring an intermediate world that this ” Schrodinger on the beach “, an exploration that takes place not only in the company of the Austrian physicist and his ghost cat, but also of the grown-ups, among others Richard Feynmanfrom Thomas Young and his infinitely simple and perfectly diabolical slits of light, by Louis de Broglie and his counterintuitive notion of matter waves, byHeisenberg and matrices of the discontinuous, from John Wheeler and his delayed choice experiments, orHugh Everett and his theory of many worlds often mentioned by science fiction writers, for example by Blake Crouch in “recursion”.

The history of quantum physics is therefore also that of many geniuses, but rest assured: by learning in ” Schrödinger on the beach – quantum physics in a deck chair » that there is more energy in a vacuum than anywhere else, he will have fewer scruples about creating a vacuum in his brain for a moment in his deck chair. He will easily understand what the spins of particles are (and, by the way, know how to easily classify the latter into the families of bosons and fermions), will discover that the belt of director is more and better than an item in the famous physicist’s wardrobe, will face hair-raising counteractuality and the principles of non-locality, decoherence and correspondence, will finally breathe while learning that “simulated annealing” is not a device of the new kitchen and will not confront her with a hypothetical quantum gastronomy in which the dish of the day would be in a state of quantum superposition, i.e. dirty and delicious at the same time.

This ” Schrödinger on the beach – quantum physics in a deck chair is generally accessible, but still requires a certain concentration. Contagiously, it projects the reader into several states of quantum superposition: the state of someone who understands everything superimposed on the state of someone who no longer understands anything, the state of someone feeling intelligent superimposed on the state of one who understands the Impression has hit an unshakable conceptual wall, the state of one letting go of their vacation superimposes the state of one continuing to stimulate their neurons. Deck chair or no deck chair, highly recommended reading to better understand the physical environment in which we live and to understand the thousand and one scientific advances that will rock our world in a very short time.
