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 Grasshopper robot 08.05.2022 Engineers at the University of California at Santa Barbara have designed an artificial grasshopper that can jump over 30 meters. At the same time, its design itself reaches only 30 centimeters in height. The whole construction work acts like a spring. It consists of rubber bands and carbon fiber slats. When the actuator (Light Rotating Motor) rotates, it winds the string that compresses the spring. So the drive pulls on the rubber bands and compresses the carbon fiber, bending each bar into a curved shape, similar to a shooting bow. After that, the latch is released and the robot is thrown into the atmosphere. This mechanism is similar to those used by animals. For example, the leg muscle of a grasshopper also serves as an actuator: when it contracts, it bends the spring-like part of the knee joint, creating the tension necessary for jumping. The robot can jump over buildings and move efficiently in environments where the movement of wheeled, walking or flying structures is complicated. Also in the future, such mechanisms can be used in the space industry. They are capable of jumping more impressive distances in airless, low gravity environments. Researchers have already begun working with NASA to refine the device. Engineers hope to have a more advanced version ready for use in outer space in 5 years.
