Cryptography is, beyond any doubt, an important technology. Keeping the privacy of communications has many applications in modern societies. For instance, being able to send a message, as your credit card number, with the confidence that no one will understand it if it is intercepted, is a basic assumption for electronic transactions. Also, nowadays and […]
Artificial intelligence (AI) is one of the most actives fields of computer science. The idea of a computer learning, in an autonomous way, complicate tasks is exciting from both the fundamental and applied points of view. One very recent and interesting approach to this problem is Deep Learning . This technology is becoming popular very […]
Quantum computers are one of the most promising technologies under development, and all their promises are completely justified. Quantum systems are extremely expensive to compute, where “expensiveness” can be measured either by the memory or the computational time required in classical computers. But it should be much cheaper if the computer uses quantum mechanics rules […]
Olfaction is one of the most important senses. It protects us from eating spoiled food, it helps animals to detect their relatives, it makes the perfume business quite successful and, in general, it connects us to the volatile chemicals surrounding us. These chemicals, usually called “odorants”, can be detected even if they are in a […]
Thermodynamics is one of the oldest and more fruitful fields of science. Quantum mechanics, on the other hand, is less than one hundred years old, but it is also useful and well accepted. They can look very different. Thermodynamics treats with macroscopic systems, composed by an Avogadro number (6.023×1023) of atoms or molecules, and quantum […]
Quantum mechanics is one of the most fruitful and accepted physical theories. Nevertheless, its foundations and philosophical implications are still a vivid topic of debate. Because of that reason, during the conference “Quantum Physics and the Nature of Reality,” held in July 2011 and organized by Anton Zeilinger, a set of experts were polled. A […]
Quantum mechanics and biology are very different fields. The first one studies things that are very small, like atoms, molecules or particles. Biology, on the other hand, deals with complex and big systems, the living beings. Of course, that does not mean that there is no connection at all. Big, complex systems are composed always […]
Causality is one of the oldest and most important concepts of Physics. Even recently, at the beginning of the XX century, with the invention of Special Relativity, this concept was in some sense rediscovered. As in a relativistic framework the events can change their temporal order a great effort was made in order to preserve […]
