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 FET SuperMESH3 24.02.2009 STMicroelectronics has expanded its line of power field-effect transistors with a new family of highly reliable and efficient devices manufactured using SuperMESH3 technology. These transistors are intended for use in power correctors and half-bridge cascades of electronic ballasts of fluorescent lamps and in switching power supplies. The first transistors of the family are designed to operate at reverse voltages of 620 V - STx6N62K3 and STx3NK62K3, as well as 525 V STx7N52K3 and STx6N52K3. The new technology provides low channel on-resistance, reduced recovery time, gate charge and input capacitance, which ultimately improves switching properties and operating frequency. An added benefit of this technology, which combines stripline technology with an optimized vertical transistor structure, is some of the best dv/dt properties in its class. Achieving a low channel resistance also allows the use of small packages for high-voltage field-effect transistors, which ensures maximum packing density on the board. So, for example, the STx3N62K3 transistor with a resistance of 2,5 ohms is available in IPAK, DPAK, D2PAK, T0-220, TO-220FP packages.
