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, ... >>

0,34nm gate transistor 19.03.2022

A group of Chinese scientists came up with an unusual transistor design. Thanks to their unique design, they made the world's smallest transistor with a gate length of just 0,34 nm. Further reduction of the gate length using traditional technical processes is in principle impossible, because we are talking about a gate length equal to the width of one carbon atom.

The scientists called the new transistor a vertical sidewall transistor. The idea of a vertical arrangement of the transistor channel, by the way, was also recently implemented by Samsung and IBM, which we once talked about. But the Chinese developers were able to surprise. The gate in the new transistor is a slice of one atomic layer of graphene, and its thickness, as you know, is equal to the thickness of one carbon atom, or about 0,34 nm. And the most amazing thing is that no modern lithographic scanners are needed to make a shutter of this length. All the necessary fine components are created using vacuum deposition processes.

How does this happen? A conventional silicon substrate is taken. She plays the role of foundation. Silicon does not participate in electrical processes in any way, although, theoretically, it can protect against leakage currents. Two steps are made on the silicon layer from an alloy of titanium and palladium. A sheet of graphene is placed on the top step. It doesn't need precision. It will be achieved later by conventional etching. A layer of aluminum pre-oxidized in air is placed on a graphene sheet. The oxide serves as an insulator for the structure. Therefore, aluminum does not participate in the electrical circuit of the transistor, although there is no complete clarity in the purpose of the aluminum layer.

The aluminum stacking field is subjected to conventional etching, during which the graphene edge is exposed, including the cut of the aluminum lining. This forms a graphene gate 0,34 nm long with a precisely adjusted topology. Just above it, a cut of aluminum is exposed, which can already form an electrical connection with the gate, but not a direct one. At this stage, the thinnest layer of hafnium oxide, an insulator, is applied to both steps and to the side wall, which excludes the electrical connection of the gate with the rest of the transistor structure and, in particular, with the transistor channel.

A very thin layer of molybdenum dioxide (MoS2) close to the atomic thickness is applied over the hafnium oxide dielectric. Molybdenum dioxide is a semiconductor, it plays the role of a transistor channel, which is controlled by a gate in the form of a slice of graphene. This results in a structure about two atoms thick, with a gate one atom long. The drain and source of the transistor are metal contacts deposited on molybdenum dioxide. An elegant solution to the problem of Moore's law and, apparently, this will be the end of its action, if we talk about traditional technical processes.
