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 Night vision is available to everyone 02.03.2019 Fans of the sci-fi genre will probably remember the 2000 film Pitch Black, starring Vin Diesel. So, the hero of Vin Diesel in this film had night vision, obtained artificially, by special processing of the cornea of ​​​​his eyes. Such a scenario has become practically a reality thanks to the work of a team of scientists from the University of Massachusetts Medical School, who created special eye drops with nanoparticles, the use of which allows experimental rodent animals to see in the near-infrared (NIR) spectrum of light. Almost all mammals, including humans, are capable of visual perception of light that is only in the visible range. In order to expand the range of light perceived by the eyes, scientists have made nanoparticles consisting of lectin proteins, which have become the active component of eye drops. With these drops, scientists treated the eyes of experimental animals and, as soon as the protein nanoparticles got inside the eye, they “glued” to the photoreceptor cells in the retina. After that, additional proteins turned into a kind of nanoantennas, capable of capturing light in the NIR range, the shortest wavelength of infrared light. By absorbing photons of infrared light, proteins emit photons of green light, which are already captured by normal photoreceptor cells in the eye. Laboratory tests have fully confirmed that the experimental animals are able to clearly differentiate and respond to images created in the NIR range using a special lamp. At the same time, the introduction of protein nanoparticles did not affect the ability of the eyes to perceive ordinary visible light. Unfortunately, the artificial effect of night vision turned out to be inconsistent, it began to fade to complete disappearance after two weeks after treatment of the eyes with drops with nanoparticles. But most importantly, no adverse side effects have been observed with this treatment. "The results of our research have greatly expanded the field of practical application of modern nanotechnology" - says Professor Gang Han (Gang Han) - "Such protein nanoantennas will allow scientists to explore many intriguing things, such as the processing of visual signals in the brain of a living being. This, in turn, , can be used to treat diseases and disorders such as color blindness."
