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 ... >>

Video recording of objects will help to eavesdrop on the conversation 15.08.2014

Scientists from the Massachusetts Institute of Technology (MIT) have developed a method of eavesdropping on conversations by filming objects located in the vicinity of talking people on video cameras and analyzing the vibration of these objects.

The method works in several stages. First, the frequency and pressure of the sound waves that reach an object (such as a paper cup) are recorded. The camcorder then records the object's vibrations, converting them into pixel movements. After that, a special program converts pixel shifts into sounds.

"We were able to decipher the words of the song at a distance of 4,5 meters from the vibrations of a bag of chips behind a special soundproof glass," says Abe Davis, lead researcher. Then we managed to recognize the song of the group Queen Under Pressure, playing in the headphones, by the vibrations of their cord. Moreover, it was even possible to recreate the original sounds from the video recording of the candy box, which was next to the humming person. The new technology also makes it possible to determine the gender of the speaker. However, it does not yet allow to parse ordinary speech.

The authors of the article rightly note that intelligence already uses laser microphones for listening by reading information from vibrating surfaces. But for successful work, they need to eavesdrop on conversations behind glass, and transparent and clean. Thanks to the new method, it is possible to "remove" vibrations from almost any object.

As Davis notes, measuring the physical properties of distant objects using new technology is more interesting for him than intelligence activities.

"The response of objects to sound speaks to their unexpected structural properties," the scientist points out.
