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 ... >>

New method for creating powerful batteries 08.05.2024

With the development of technology and the expanding use of electronics, the issue of creating efficient and safe energy sources is becoming increasingly urgent. Researchers at the University of Queensland have unveiled a new approach to creating high-power zinc-based batteries that could change the landscape of the energy industry. One of the main problems with traditional water-based rechargeable batteries was their low voltage, which limited their use in modern devices. But thanks to a new method developed by scientists, this drawback has been successfully overcome. As part of their research, scientists turned to a special organic compound - catechol. It turned out to be an important component that can improve battery stability and increase its efficiency. This approach has led to a significant increase in the voltage of zinc-ion batteries, making them more competitive. According to scientists, such batteries have several advantages. They have b ... >>

Alcohol content of warm beer 07.05.2024

Beer, as one of the most common alcoholic drinks, has its own unique taste, which can change depending on the temperature of consumption. A new study by an international team of scientists has found that beer temperature has a significant impact on the perception of alcoholic taste. The study, led by materials scientist Lei Jiang, found that at different temperatures, ethanol and water molecules form different types of clusters, which affects the perception of alcoholic taste. At low temperatures, more pyramid-like clusters form, which reduces the pungency of the "ethanol" taste and makes the drink taste less alcoholic. On the contrary, as the temperature increases, the clusters become more chain-like, resulting in a more pronounced alcoholic taste. This explains why the taste of some alcoholic drinks, such as baijiu, can change depending on temperature. The data obtained opens up new prospects for beverage manufacturers, ... >>

Signal transmission through human tissue 13.04.2020

A team of developers from Finland has demonstrated the operation of a method of signal transmission to implants placed inside biological tissue that is safe for living organisms. The signal cannot be intercepted, blocked or changed from a long distance.

Professor Marcos Katz of the University of Oulu has led research for many years to find alternative ways to communicate. In 2017, together with colleagues, the scientist developed a hybrid communication channel that can smoothly switch between the transmission modes of radio waves and waves in visible light using VLC (Visible Light Communication) technology. The channel operation mode depended on its state and transmitted information.

When testing, the radiation wavelength was increased from a few millimeters to several centimeters and found a good connection even for deeply located implants. The external signal source was located at a distance of several meters from the "body".

The first results - 10 kilobits per second - did not please scientists too much. Then she increased the number of receivers / signal sources, conjured over modulation schemes and received a multiple increase in the transmission rate.

The technology of transmitting a signal using infrared radiation is useful not only in communication applications. The VLC can be used to control, for example, pacemakers and defibrillators. At the same time, radio interference or someone's malicious intent will not be able to cause the failure of this vital equipment.

It is with the use of technology in the medical field that the future research of the Finnish team is connected. The developers hope to contribute to the development of methods for diagnosing and treating diseases, as well as controlling devices implanted in the human body. It remains only to better understand the biological tissue as a conducting medium for infrared radiation.
