Clarke

The Nobel Prize in Physics of 2024 has been awarded to John Clarke, Michel H. Devoret and John M. Martinis “for the discovery of macroscopic quantum tunnelization and the quantification of energy in an electrical circuit.” The Nobel Committee He has decided Highlight the important advance that has been seen in the quantum field and that today are the basis of all the digital technology that we use practically daily. Quantum mechanics. Those awarded this Nobel did experiments in 1984 and 1985 with a closed electrical circuit with superconductors. The key in this case was that among the drivers there was an area that was not a conductor. Thanks to this, both the typing tunnel effect and “quantized energy levels in a system large enough to hold it in hand were allowed to demonstrate.” Something that could be wonderful on paper, but that had to be carried out with the aim of being fully functional and had a real application in our day to day. Applications. Thanks to this work we know the technology as it is, because its applications are many today. One of the clearest examples is in the transistors of computer microchips that is in almost everything around us. But beyond this he has also given quantum cryptography or quantum computers. Tunnel effect A concept that can be very difficult to understand, but that from the Nobel committee have wanted to exemplify with an example: It would surprise you very much if the ball suddenly appeared on the other side of the wall. In quantum mechanics, this type of phenomenon is called a tunnel effect and is precisely the type of phenomenon that has given it the reputation of being strange and not very intuitive. In this case, the winners were able to demonstrate with a series of experiments that the (very strange) properties of the quantum world can be sustained in their hand in a sufficiently large system. In this way, the electrical system they have designed allows you to pass from one state to another through a tunnel as if the ball crossed the wall, when a priori seems impossible. And it is precisely what has been awarded: to take the tunnel effect on a macroscopic scale in a centimeter chip. The pools. As every year, there are many candidates who can come to mind when thinking about this award, and that ‘the shots’ go to roads that are very different. On the one hand, it points to the moment of boiling and the enthusiasm around the quantum information that is fundamental for the security of communications or in problem solving. On the other hand, the pools also point to the physics of materials that always give us some kind of surprise throughout the year. But if we change completely, we could also have gone to the field of astrophysics and the advances that have been made in the study of the cosmos and that in recent years has always given many surprises. The prize. The Nobel Prize in Physics has a wide history since the first recognition was granted in 1901 to Wilhelm Conrad Röntgen. In its long history it has been granted on 117 occasions and 225 people have been recognized with the most distinctive prize. On the ‘bad’ side is that this is the award that has less women has awarded: only five. As a striking history, Marie Curie is one of the few people who has received two Nobel noise throughout her life: that of Physics in 1903 and Chemistry in 1911. And if we talk about ‘double awards’, we must also highlight John Bardeen who is the only person who has won this Nobel twice: in 1956 and 1972.
