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 Wireless BLE sensor STEVAL-BCN002V1B 17.12.2019 The new STEVAL-BCN002V1B Bluetooth Low Energy Sensor Node Wireless Development Kit includes the STEVAL-BCN002V1 multi-sensor board based on the BlueNRG-2 SoC chip acting as the control processor. This sensor board is equipped with an accelerometer, a gyroscope, a magnetometer, a pressure, humidity and temperature sensor, a ToF distance meter and a MEMS microphone. Autonomous power supply is provided by the disk element CR2032. The sensor board communicates with a Bluetooth LE-enabled smartphone running the ST BLE Sensor app, which can be downloaded free of charge from the Google Play and iTunes stores. The STEVAL-BCN002V1D accessory board is used for programming and debugging the sensor. The accessory board is connected to the PC via USB. The STEVAL-BCN002V1B kit with STEVAL-BCN002V1 sensor board and STEVAL-BCN002V1D programming board includes: BlueNRG-2: Bluetooth Low Energy system-on-a-chip; BALF-NRG-02D3: ultra-miniature balun and harmonic filter; LSM6DSO: iNEMO 6DoF low power inertial module; LIS2MDL: 3-axis magnetometer with digital output; VL53L1X: ST FlightSense rangefinder (photon flight time); MP34DT05TR-A: omnidirectional digital MEMS microphone; LPS22HH: piezoresistive absolute pressure sensor (barometer); HTS221: capacitive digital relative humidity and temperature sensor; Cell holder CR2032 (battery not included). To develop applications based on the STEVAL-BCN002V1B, the STSW-BLUETILE-DK software suite is available, which extends the STSW-BLUENRG1-DK software for BlueNRG-1 and BlueNRG-2 wireless microcontrollers by adding drivers for all sensors, a middleware library, and several BLE application examples.
