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 ... >>

Mini air conditioner Sony Reon Pocket 5 09.05.2024

Summer is a time for relaxation and travel, but often the heat can turn this time into an unbearable torment.

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 ... >>

Random news from the Archive Human-mouse hybrid 29.09.2021 American scientists report an unprecedented success in the integration of living human cells into the organisms of other animals. In particular, they managed to create the most perfect hybrid of a mouse and a human to date - something impossible in ordinary nature. Such chimeras are extremely important and necessary for science, but they are not at all spectacular from the point of view of, for example, cinema - instead of nightmarish monsters, ordinary-looking rodents grow in cages. To be precise, not a single mouse-human hybrid has ever been grown to adulthood, all embryos, including the most successful ones, are destroyed on the 17th day of life. Not because of safety requirements - scientists are sure that such creatures are no more dangerous than an ordinary mouse. There is simply no point in wasting resources and time on an intermediate result - with only 0,1% of human cells in the mouse body, it is of no practical interest. And even today's record 4% of human cells in the mouse body is just a reason for the personal pride of researchers. The method itself is much more interesting - scientists managed to calibrate human stem cells, achieving approximately the same growth rate as mouse cells. This made it possible to carry out mutual integration, but it did not lead to the desired result. Human cells partially settled in the liver and hearts of mice, but most of them simply turned into red blood cells. The very fact of the presence of human cells in the body of a mouse does not give anything; for science, it is important to obtain entire organs, systems, such as the circulatory or respiratory systems. To set up experiments, use human mice as the optimal laboratory model. On the one hand, this makes it possible to study the problems of treating human organs, on the other hand, hybrids breed and are exploited like ordinary mice, in large quantities and cheaply.
