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

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 Car Wi-Fi will improve road safety 30.08.2014 The American authorities intend to oblige automakers to equip their vehicles with wireless networks, with the help of which cars on the roads will interact with each other. Such "communication" can annually save several hundred lives. The US National Highway Traffic Safety Administration (NHTSA) is calling for the rapid development of a national standard for automatic exchange between moving vehicles in close proximity to each other. Such communications, called Vehicle-to-vehicle (V2V), will help increase the speed of urban and suburban traffic, warn drivers about traffic jams and adverse weather and road conditions, and build a route based on this information. V2V technologies will also improve road safety. According to NHTSA estimates, the massive introduction of just two Left Turn Assist and Intersection Movement Assist systems will help prevent up to 592 accidents per year and save about 1080 lives. Left Turn Assist is a technology that warns drivers that they will not have time to make a left turn at an intersection, taking into account the speed of oncoming traffic. The Intersection Movement Assis function, estimating the location and speed of vehicles traveling nearby, will notify you of a possible danger of crossing roads. V2V communication functionality also includes blind spot monitoring, oncoming collision warning, emergency braking information for the vehicle in front, and more. According to ABI Research researchers, by 2027, about 62% of new machines will be equipped with communication technologies. They are already being tested by many automakers. For example, Ford has developed an "electronic brake light" that signals to other road users that the driver has braked hard. A special alert appears on the dashboard of their cars. For the national V2V standard, the US traffic safety authorities propose to allocate the 5,85-5,925 GHz frequency range, as well as use the IEEE 802.11p standard, which is a type of Wi-Fi for use in vehicles. Installing V2V communications will increase the cost of the vehicle by an average of $340-$350. In the future, it will be possible to reduce these costs to $209-$227, the department says.
