Room-temperature superconducting microprocessors. And Lazarus superconductivity.


Lazarus-superconductivity means the case where superconductivity vanishes and returns. That thing makes it possible to adjust the superconductivity or switch resistance on and off. And that makes a revolution for microchips. But first to room-temperature superconductors. 

It's possible to make superconductivity at room temperature. That thing requires about 3 million atmosphere pressure. But the fact is that magnetic fields can press the layers with very high pressure. Theoretically, room-temperature superconducting microchips can use 2D material architecture. The 2D materials mean that there is only one atom layer in that structure. That microchip will be in the pressure chamber where the magnetic field presses water. 

The fact is that 3 million atmospheres are very high pressure. And researchers must put those microchips in some bunkers because leaks are devastating. But then the high pressure along with the low temperature is the ultimate combination for those systems. It is also possible to create superconductivity by using symmetrical magnetic fields. 

And the thing that makes the pressure-low temperature combination interesting is the new state of superconductivity called Lazarus superconductivity. In that state the superconductivity is lost and returns. The idea of the superconductor is that resistance will be removed by stabilizing the material. The most usual method for that stabilization is to decrease temperature. 

Another method is to increase pressure to 3 million atmospheres. But the best method is a combination where high pressure along with low temperature makes the superconductivity. Superconductors are important tools for solid-state quantum computers where quantum entanglement is created in solid materials. Superconductors keep information in its shape because resistance causes oscillation that disturbs the superposition and entanglement. 



"Researchers have discovered a spatially modulating superconducting state in Uranium Ditelluride, a new and unusual superconductor. This discovery could be vital for quantum computing, providing a solution to one of its greatest challenges. (Artist’s concept.)". (ScitechDaily.com/A New Era of Superconductivity: How Uranium Ditelluride Could Shape Quantum Computing)


The new state of superconductivity is called "Lazarus superconductivity" which allows researchers to control the superconductor and switch the superconductor on and off. Researchers detected that phenomenon in a material called uranium ditelluride. 

Lazarus-superconductivity means the case  When superconductivity is lost and returns. In components where high pressure-low temperature combinations create superconduction adjusting pressure or temperature, the superconduction can switch on and switch off. If researchers could find out the superconducting material that border between superconducting and resistant states is very sharp they could use infrared holograms to adjust temperature in a very accurate position in the system.  

The term Lazarus-superconductivity means that: superconductivity will be lost, and then it will return when some parameter, like in this case, a magnetic field returns. The idea of superconductivity that can return and be lost can be the holy grail for computing. The Lazarus superconductivity can be useful in superconducting microchip technology. 

There are problems for create components, like diodes and especially switches and routers for superconducting computers. The Lazarus superconductivity makes it possible. That system can remove the superconduction from nanotechnical switches and routers. And then return to that state back. 

If researchers could create a superconductor with a very sharp border between superconducting and resistant states they could make those components and their superconductivity removed and then return. The idea is that the component will warm by using an infrared hologram or decrease the magnetic field power so the system can return resistance for routers and switches. 

The problem with superconducting components is that electricity jumps over them. And maybe Lazarus-superconductivity can deny that effect. This is the reason why LK-99-type materials are interesting even if they cannot reach superconductivity at normal pressure and room temperature.

The new bendable sensor is like straight from the SciFi movies.

"Researchers at Osaka University have developed a groundbreaking flexible optical sensor that works even when crumpled. Using carbon nanotube photodetectors and wireless Bluetooth technology, this sensor enables non-invasive analysis and holds promise for advancements in imaging, wearable technology, and soft robotics. Credit: SciTechDaily.com" (ScitechDaily, From Sci-Fi to Reality: Scientists Develop Unbreakable, Bendable Optical Sensor) The new sensor is like the net eye of bugs. But it's more accurate than any natural net eye. The system is based on flexible polymer film and nanotubes. The nanotubes let light travel through it. And then the film at the bottom of those tubes transforms that light into the image. This ultra-accurate CCD camera can see ultimate details in advanced materials. The new system can see the smallest deviation in the materials.  And that thing makes it possible to improve safety on those layers. The ability to see ultra-small differences on surf

Quantum breakthrough: stable quantum entanglement at room temperature.

"Researchers have achieved quantum coherence at room temperature by embedding a light-absorbing chromophore within a metal-organic framework. This breakthrough, facilitating the maintenance of a quantum system’s state without external interference, marks a significant advancement for quantum computing and sensing technologies". (ScitechDaily, Quantum Computing Breakthrough: Stable Qubits at Room Temperature) Japanese researchers created stable quantum entanglement at room temperature. The system used a light-absorbing chromophore along with a metal-organic framework. This thing is a great breakthrough in quantum technology. The room-temperature quantum computers are the new things, that make the next revolution in quantum computing. This technology may come to markets sooner than we even think.

Humans should be at the center of AI development.

"Experts advocate for human-centered AI, urging the design of technology that supports and enriches human life, rather than forcing humans to adapt to it. A new book featuring fifty experts from over twelve countries and disciplines explores practical ways to implement human-centered AI, addressing risks and proposing solutions across various contexts." (ScitechDaily, 50 Global Experts Warn: We Must Stop Technology-Driven AI) The AI is the ultimate tool for handling things that behave is predictable. Things like planets' orbiting and other mechanical things that follow certain natural laws are easy things for the AI. The AI might feel human, it can have a certain accent. And that thing is not very hard to program.  It just requires the accent wordbook, and then AI can transform grammatically following text into text with a certain accent. Then the AI drives that data to the speech synthesizer. The accent mode follows the same rules as language translation programs. The ac
