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 brain temperature 08.06.2022 Scientists from the Laboratory of Molecular Biology of the Medical Research Council in Cambridge were able to measure the temperature of the human brain. Forty volunteers aged 20-40 years were recruited, whose brains were scanned in the morning, afternoon and late evening using magnetic resonance spectroscopy. At the same time, an activity monitoring device was attached to the wrist of the participants in the experiment, which makes it possible to take into account differences in genetics and lifestyle - the biological clocks of "owls" and "larks" work differently. The temperature of the organ varies depending on the region of the brain, age, gender, time of day and the menstrual cycle in women. The average brain temperature was 38,5 degrees, more than two degrees above the temperature measured under the tongue. The surface of the brain was generally colder, while the deeper structures of the brain were often warmer than 40 degrees (the record during the study was 40,9 degrees). The temperature of the brain constantly changed depending on the time of day by almost one degree, while the highest was observed during the day, and the lowest was at night. It is noteworthy that, on average, the female brain was 0,4 degrees warmer than the male. Experts believe that this gender difference is most likely due to the menstrual cycle, since most of the participants in the study were scanned in the post-ovulatory phase of their cycle: their brain temperature was about 0,4 degrees higher than that of women who were in the pre-ovulation phase. The temperature of the brain increased with the age of the participants, especially in the deep regions of the brain.
