The speech of sperm whales is similar to that of humans 18.05.2024

In the world of the ocean, where the mysterious and unknown coexists with the studied, sperm whales, with their huge brains, are of particular interest to science. Researchers, working with a huge array of audio recordings collected during the Dominica Sperm Whale Project (DSWP) - more than 8000 recordings, seek to unravel the secrets of their communication and understand the structure and complexity of the language of these mysterious creatures. By studying in detail the recordings of 60 sperm whales in the eastern Caribbean, scientists have revealed surprising features of their communication, revealing the complexity of their language. "Our observations indicate that these whales have a highly developed combinatorial communication system, including rubato and ornaments, which indicates their ability to quickly adapt and vary during communication. Despite significant differences in evolution, sperm whales have elements in their communication that are characteristic of human communication," says Shane Gero, a biologist at Carleton University and director of the CETI project.

Electron spin for quantum information transfer 18.05.2024

The transfer of quantum information remains one of the key tasks of modern science. Recent advances in the use of electron spin to expand the capabilities of information transfer in quantum systems have become very important. Researchers at Lawrence Berkeley National Laboratory are pushing the frontiers of quantum information science by experimenting with the possibilities of electron spin. Electron spin, a natural quantum bit, is a potentially powerful means for storing and transmitting information in quantum systems. Magnon wave packets, collective excitations of electron spin, have revealed their potential to transmit quantum information over significant distances. The work of Berkeley Lab researchers has revolutionized the way such excitations propagate in antiferromagnets, opening up new prospects for quantum technologies. Using pairs of laser pulses, scientists disrupted antiferromagnetic order in one place and simultaneously studied it in another, creating ... >>

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 ... >>

quantum integrated circuit 30.06.2022

Australian developers reported significant progress in the development of quantum computers. Based on almost 20 years of scientific work by Australian teams, a young company from Australia - Silicon Quantum Computing (SQC) - was able to create the world's first quantum integrated circuit. The chip is able to simulate the behavior of just one molecule - polyacetylene, but it does it much better than classical computers.

Designed and manufactured in Sydney, SQC's Quantum Processor is an analog solution for simulating the quantum states of molecules. The company still only dreams of a real quantum processor with the ability to correct errors. But even the molecular simulator promises a breakthrough for the field once such chips are commercially produced.

A quantum chemical compound simulator will help you discover unusual materials and substances for pharmaceuticals and industry. Now we cannot even imagine what properties these materials will have, because such calculations are either impossible on a conventional computer, or will take years, centuries, and even longer as the connections become more complex.

The creation of the first SQC quantum integrated circuit required the implementation of three separate technologies. First, it was necessary to create elements of atomic size so small that their energy levels would equalize, and electrons could easily pass through them. Secondly, it was necessary to implement the possibility of adjusting the energy levels of each element separately, as well as all elements together, in order to control the passage of quantum information.

Finally, it was important to learn how to control the distance between the elements with an accuracy of less than a nanometer, so that the elements remained close enough to each other, but this would not interfere with the quantum coherent transfer of electrons along the chain. All three technological tasks were successfully solved and, as the developers emphasize, this happened two years ahead of schedule.
