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 Babies notice things that elude adults. 11.07.2023 We can usually recognize an object even if it flashes before us for a short time. However, if another object appears immediately after the first one, the perception of the first object suffers and we stop noticing its presence. This phenomenon of visual perception is called "reverse masking". In science, it is used to study how the brain processes visual signals. Interestingly, this phenomenon occurs even in cases where the second object does not spatially overlap the first one, but is represented, for example, by a contour or by four points surrounding the object. It is assumed that the occurrence of this phenomenon is associated with a violation of the "feedback mechanisms". The visual information we see is processed sequentially in the brain from lower to upper visual areas. However, feedback also plays an important role in visual perception, when visual signals are transmitted from the upper regions of the brain to the lower ones. It is believed that backmasking occurs due to disturbances in feedback processing. The scientists applied the reverse masking technique to infants between the ages of 3 and 8 months to study the development of feedback mechanisms. To test for backward masking in infants, the researchers showed them images of faces on a computer screen and measured the time the children paid attention to them. This step turned out to be fairly easy, as babies tend to look at faces longer. The face images were presented in two ways: in one case, the mask image followed the face, and in the other case, nothing appeared after the face. The researchers found that children aged 7-8 months could not distinguish between faces followed by a mask. This indicates that they, like adults, experience the reverse masking effect. However, children aged 3-6 months were able to perceive faces even when they were followed by a mask. That is, reverse masking did not occur, and infants could see faces that are invisible to older children. These results suggest that feedback mechanisms are immature in infants under 7 months of age. The study showed that the processes of visual perception change significantly in the second half of the first year of life.
