The existence of an entropy rule for quantum entanglement has been proven


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. The discovery of Regulus and Lamy shows that quantum entanglement follows an entropy rule similar to that for classical systems.

This discovery opens up new perspectives in 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.

The discovery of a new entropy rule for quantum entanglement represents an important step in understanding the fundamental properties of quantum systems. Despite the open questions, this discovery opens new horizons for the development of quantum technologies and further research in this exciting field of science.

Sound-absorbing silk 17.05.2024

In a world where noise is becoming increasingly intrusive, the emergence of innovative materials that can reduce its impact is of great interest. MIT researchers have unveiled a new sound-absorbing silk fabric that promises to revolutionize quiet spaces. The Massachusetts Institute of Technology (MIT) has made significant breakthroughs in the field of sound absorption. Researchers have developed a special silk fabric that can effectively absorb sound and create cozy, quiet environments. The fabric, thinner than a human hair, contains a unique vibrating fiber that is activated when voltage is applied to it. This feature allows the fabric to be used to suppress sound waves in two different ways. The first method uses fabric vibrations to generate sound waves that cover and cancel out unwanted noise, similar to noise-canceling headphones. This p ... >>

High Energy Density Capacitor 17.05.2024

Energy plays a key role in many aspects of modern life, and the ever-increasing demand for efficient and fast-charging power sources is driving innovation. Researchers at the McKelvey School of Engineering at Washington University in St. Louis have taken a significant step forward with a high-energy-density capacitor that promises to revolutionize the world of energy. A team of scientists from the McKelvey School of Engineering at Washington University in St. Louis presented the results of their latest research on heterogeneous thin-film structures for capacitors. Researchers, working with ferroelectrics, inadvertently created a capacitor with an amazing energy density that is 19 times higher than that of conventional elements. This breakthrough opens up new prospects for the development of fast-charging batteries, which are so necessary in the modern world. Capacitors play a key role in various devices, providing stable ... >>

Causes of conflicts between brothers and sisters 16.05.2024

Family relationships are often complex and multi-layered, and conflicts between siblings are no exception. Research in this area can help us understand what factors underlie these conflicts and why they occur so frequently. Let's look at some of the findings from psychologists at Arizona State University. American psychologists from Arizona State University conducted a study aimed at identifying the causes of conflicts between brothers and sisters. They found that different forms of violence, whether physical or verbal, did not depend on the gender of the siblings. This means that both girls and boys can exhibit aggressive behavior towards their loved ones. Other studies have shown that conflict between siblings often persists into adulthood, even as contact decreases. This indicates that people often follow established patterns of behavior formed in childhood. It was also found that, despite ... >>

Washing vacuum cleaner Dyson WashG1 16.05.2024

Modern technologies strive to make the home cleaning process more efficient and convenient. New from Dyson, the WashG1 washable vacuum cleaner is an innovative approach to cleaning that differs from traditional models. Dyson, a leading manufacturer of household appliances, introduced a new model of the WashG1 washing vacuum cleaner, which has brought revolutionary changes in the field of home cleaning. A distinctive feature of this model is its unique design, which abandons the traditional suction mechanism. The WashG1 work attachment is equipped with two microfiber-coated rollers, each with 64800 threads per 1 cm2. These rollers work in opposite directions, effectively removing all dirt from the floor. A special feature of this model is the ability to automatically clean the rollers: dirty parts of the rollers are washed with clean water and combed with a nylon brush. The collected garbage is collected in a special container, and dirty water passes through a plastic mesh and enters ... >>

Products in beautiful wrappers seem useful to people 15.05.2024

Attractive food packaging plays an important role in today's market. Many of us succumb to the temptation of beautifully designed packaging, associating them with high-quality and healthy products. However, how useful are these products really and how does our perception perceive them? Let's look at the results of a study conducted by scientists from the University of Southern California to understand how the appearance of packaging affects the way we think about products. A study conducted by researchers at the University of Southern California found that attractive food packaging can have a significant impact on perceptions of its healthfulness and quality. Aesthetically designed packaging can make us perceive products as healthier and better quality than they actually are. As part of the experiment, participants were offered the same products, but in different packaging: one group saw beautifully decorated avocado toast, while the other group saw ... >>

Sociology of organ transplant 06.05.2006

A Gallup poll of 1900 people in the United States found that more than half of American adults would not mind transplanting their organs after death to those in need.

The willingness to donate their organs is the same in men and women, but varies in different age groups and races. At the age of 35 to 44, more than 75% of the population are ready to donate their organs, at the age of 18 to 24 - 55%, and over 65 - only 38% (perhaps because they mistakenly think that the organs of older people are nowhere to be found). fit).

The racial breakdown is as follows: among whites and people of Asian origin, 62% agree to donate their organs to those in need, among Hispanic Americans - 47%, and among blacks - only 25%.

Among black Americans, there is a high level of distrust not only in transplantology, but in medicine in general. However, it is precisely in this group that most of all need a transplant. Although African Americans make up 13% of the US population, they make up 35% of those waiting for a kidney transplant (the most common transplant operation).
