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 100 Mbps for ISS 03.05.2020 A four-year-old project to create satellite systems for high-speed communication between space and ground stations is undergoing field testing. The equipment delivered earlier to the ISS made it possible to establish a downlink laser communication channel with a bandwidth of 100 Mbit/s with the ground station. The developer of technology and equipment was Sony. Developed by Sony in collaboration with the Japan Aerospace Exploration Agency (JAXA) and the National Institute of Information and Communications Technology (NICT), the communication equipment is based on laser optical disc recording technology. Sony has a wealth of experience in this. By adapting data encoding mechanisms for writing to disk for transmission over an optical (laser) channel, the company was able to help develop the foundations of laser space communications. Communication equipment was delivered to the ISS in September last year. Then it was mounted on an open Japanese Kibo module. Tests and equipment adjustments were carried out about once a week, when the weather allowed. For the first time, the SOLISS (small optical link for the International Space Station) downlink laser was installed on October 25, 2019. The first bi-directional link using a 1,5 µm laser was installed with a ground station on 5 March. The first HD images from the ISS were received via a laser Ethernet channel on March 11. A series of experiments with equipment for laser communication will last until June 2020. It is assumed that communication via SOLISS channels will provide real-time transmission of large data arrays both between space stations, which will be required in further lunar and Martian missions, and between spacecraft and ground stations.
