The existence of an entropy rule for quantum entanglement has been proven 09.05.2024

Quantum mechanics continues to amaze us with its mysterious phenomena and unexpected discoveries. Recently, Bartosz Regula from the RIKEN Center for Quantum Computing and Ludovico Lamy from the University of Amsterdam presented a new discovery that concerns quantum entanglement and its relation to entropy. Quantum entanglement plays an important role in modern quantum information science and technology. However, the complexity of its structure makes understanding and managing it challenging. Regulus and Lamy's discovery shows that quantum entanglement follows an entropy rule similar to that for classical systems. This discovery opens new perspectives in the field of quantum information science and technology, deepening our understanding of quantum entanglement and its connection to thermodynamics. The results of the study indicate the possibility of reversibility of entanglement transformations, which could greatly simplify their use in various quantum technologies. Opening a new rule ... >>

Energy from space for Starship 08.05.2024

Producing solar energy in space is becoming more feasible with the advent of new technologies and the development of space programs. The head of the startup Virtus Solis shared his vision of using SpaceX's Starship to create orbital power plants capable of powering the Earth. Startup Virtus Solis has unveiled an ambitious project to create orbital power plants using SpaceX's Starship. This idea could significantly change the field of solar energy production, making it more accessible and cheaper. The core of the startup's plan is to reduce the cost of launching satellites into space using Starship. This technological breakthrough is expected to make solar energy production in space more competitive with traditional energy sources. Virtual Solis plans to build large photovoltaic panels in orbit, using Starship to deliver the necessary equipment. However, one of the key challenges ... >>

Brain of a criminal as evidence 16.03.2017

Sometimes people do illegal things simply because they didn’t think about the consequences, or because they obeyed some impulse, or just for fun. And it is quite difficult to distinguish someone who "just didn't think" from someone who really wanted to do exactly what he did, for the sake of some kind of benefit - you need to look for motives, delve into psychology, etc. But the task can be to simplify if you include neuroscience in the case.

Reed Montague (Read Montague) and his colleagues from the Virginia Polytechnic University and other US research centers compared the brain activity of people who were asked to do an illegal thing: according to the scenario, the participants in the experiment, several dozen men and women, had to carry some " contraband" in the suitcase. In some cases, it was known that the suitcase contained “contraband”, while in others it was required to choose from two or five suitcases, one of which contained something that was not allowed, and then you could only guess what you were carrying with you. The probability that you would be caught also depended on whether there was a guard at the checkpoint - there were ten such checkpoints, and at some there were no guards.

An article in PNAS says that the scans showed a clear difference in brain function between those who took the suitcase, being sure that it contained "contraband", and those who were not sure and took the suitcase "just like that." However, these differences were clearly manifested only when the participants in the experiment saw in advance which checkpoints had guards and which did not, and only then chose a suitcase for themselves.

In this case, we are not talking about behavior - everyone had to carry the suitcase one way or another - but about the state of the brain. For some reason, the difference between intentional misconduct and unintentional arose only when a person could assess the degree of risk, that is, the number of guards and the likelihood of choosing the "wrong" suitcase. By and large, we see here that at the level of the brain, confidence in the incompetence of one's actions is clearly different from the situation when a person simply does something for the sake of the process itself, hoping that everything will work out.

True, although we have said that something like this neurobiological test could help forensic scientists distinguish between reputable criminals and unintentional ones, it is not clear how exactly this should work in practice. It is necessary to clarify that in this case, it was not the background activity of the brain that was determined, which could be the “calling card” of the criminal (in general, the question is whether there is such a “background activity” in nature, unless in mentally ill people), but about situational changes in work of nerve centers. That is, if we have a criminal situation, the brain can work this way or that, and depending on the result, we can judge the intentions of a person.
