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 ... >>

Magnetic heads polished with green tea 19.07.2004

Engineers from Arizona have figured out how to make a cheap and, most importantly, biodegradable liquid for polishing magnetic heads based on green tea.

The reading heads of magnetic disks must be polished very carefully: if bumps occur on the surface, their height should not exceed ten angstroms. To wash off all kinds of dust particles, as well as particles of polishing powder, a liquid with sticky additives is used.

As you might guess, usually these substances are specially synthesized, and, being too tough for soil microbes, they pollute the environment after use. The volume of such waste is not small - more than 160 million hard drives are produced per year. Therefore, there is a desire to replace synthesized substances with natural ones: they were originally intended for food by microorganisms.

In the liquid for polishing magnetic heads, engineers from the small company "Ventana Research Corporation" while working on a grant from the National Science Foundation (USA), allocated under the program for supporting innovative research, suggested adding components of green tea extract.

"These are the substances that create a dark coating on tea and coffee cups," says John Lombardi, CEO of the company. , available raw materials - tea leaves".

Guessing that the sticky substance should be looked for in tea was not easy. A case helped here: one day the head of the work noticed that the structure of the components of the glue with which sea acorns are glued to the bottom of ships is similar to tea tannins. Well, it was a matter of technology to isolate the appropriate substance from the plant.
