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 ... >>

Random news from the Archive wooden chip 06.06.2015 Researchers at the University of Wisconsin-Madison and the US Department of Agriculture have developed a chip that uses cellulose, a substance obtained by processing wood (cellulose is also used to make paper), on a substrate that houses semiconductor transistors. According to the project leader, professor of electrical engineering Zhenqiang Ma (Zhenqiang Ma), the substrate in the chip accounts for the bulk of the material. So the researchers are talking about developing a chip "virtually entirely made of wood." Cellulose fibers, which the researchers managed to obtain, have the necessary strength to accommodate transistors. However, the surface of the material is not flat enough for this purpose. Moreover, cellulose well absorbs moisture from the surrounding air and as a result swells - which will certainly lead to the destruction of the microcircuit. In order to make cellulose suitable for use as a substrate, the research team applied an epoxy composition to it. This helped to solve both problems at once - both the problem of uneven surface and the problem of swelling, said Ma. "The main advantage of cellulose fiber over polymers is that it is made from plant materials, while most other polymers are made from petroleum products. Biopolymers are safer for the environment, they rot quickly and are easily recycled," the project leader explained. In addition to using the new material as a substrate in a chip, the researchers demonstrated a way to place a much larger number of transistors on a cellulose substrate compared to traditional semiconductor industry technologies. In particular, on a substrate with an area of ​​30 sq. m, the researchers were able to place 1,5 thousand transistors made of gallium arsenide, while usually only eight to 40 transistors are placed on such an area. According to the project participants, this method can significantly reduce the amount of toxic electronic waste accumulated on Earth.
