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 Nanowires three atoms in diameter 29.12.2016 A group of scientists from Stanford University and the Stanford Linear Accelerator Laboratory (SLAC) has discovered the possibility of using the smallest particles of diamonds - adamantanes (diamondoid) - conductive nanowires with a diameter of only three atoms. Moreover, each such wire is enclosed in a reliable shell of diamonds, which makes them strong enough and protected from short circuits with each other. Such nanowires can find applications in optoelectronics for data transmission, as a solution for generating energy from the sun or in other areas. For example, it is possible to produce fabric for clothes with sewn-in electronics or solar panels invisible to the eye. The most important part of the development was such properties of the new material as self-assembly. According to scientists, nanowires are assembled like a LEGO constructor. The role of "cubes" with grooves and guides in the assembly of nanowires is played by the smallest particles of diamonds. By the way, the solution with diamond particles for experiments was obtained from oil produced in the state of Arkansas. The oil in this area has all the impurities necessary for growing "diamond" nanowires. But for the solution, it underwent a special cleaning, during which "cubes" of approximately the same size remained in the mixture. In addition to adamantanes, each of which has one sulfur atom attached, a solution of copper sulfide was used to grow nanowires. In solution, the molecular lattice of adamantanes began to be affected by attractive forces in the form of van der Waals forces. Adamantanes began to stack one after another, involving copper atoms in the process, and the wires grew in one direction. Scientists have proven that this is a precisely controlled process, which allows us to talk about good prospects for development. In addition to copper, experiments with the self-assembly of "three-atom" nanowires were carried out with cadmium, zinc, gold, and silver. Each of these or other materials gave the wires different and unique properties. The use of cadmium, for example, made it possible to give the wires the characteristics of LEDs. Other materials have promised to give nanowires the properties of piezocrystals, and this is the direct conversion of mechanical deformations into electricity (energy-producing fabric of a suit or sports uniform). Nanowires have many prospects. It would be nice to wait for commercial implementation.
