Revolution in biomedicine using emerging of picomaterials: A breakthrough on the future of medical diagnosis and therapy

Posted by in categories: biotech/medical, chemistry, quantum physics

Pico technology is hypothetical future level of technology which will revolutionized the scientist world. This technology is combination of pico and meter with scale of trillionths of a meter (10−12). This atomic and subatomic range particles reveals extraordinary properties and pave the way for tremendous applications [1].

The way lengths and angles attach together is the main determine of the materials properties. Alterable or reversible bonds distortions at pico-meter scale which changes the electronic conformation causes multiple properties for materials.

On the other hand, pico-scale particles changes the material properties by converting energy state of electrons within an atom. Physical and chemical properties of systems such as melting point, fluorescence, electrical conductivity, magnetic permeability, and chemical reactivity changes basically at pico-scale due to quantum effects of materials [2]. Moreover, surface energy of atoms increases by alternation of electron distribution and therefore, enhances protein and molecules adsorption on to materials. This privileges will resulting in tracing proteins, DNA and molecules and labeling them for various purpose.

DARPA Selects Research Teams to Enable Quantum Shift in Spectrum Sensing

Posted by in category: quantum physics

DARPA today announced the research teams selected for the Quantum Apertures (QA) program, which seeks to develop a fundamentally new way of receiving radio frequency (RF) waveforms to improve both sensitivity and frequency agility for defense applications. The selected teams will be led by Honeywell, Northrop Grumman, ColdQuanta, and SRI International.

The QA program aims to develop RF antennas, or apertures, that use quantum techniques to alter the way the RF spectrum is accessed. The goal is to develop portable and directional RF receivers with significantly greater sensitivity, bandwidth, and dynamic range than any classical receiver available today.

“Today, commercial wireless infrastructure, the construct of spectrum use, and beyond have been dictated by a hundred years’ worth of antenna theory, originally developed by German physicist Heinrich Hertz,” said John Burke, the program manager leading the QA program. “With the introduction of quantum, we have the ability to replace the existing fundamental limits placed on antenna technology with a whole new set of rules. Quantum Apertures seeks to create a paradigm shift in the way we access and use the spectrum.”

Evolving threat

Posted by in categories: asteroid/comet impacts, biological, biotech/medical, cyborgs, evolution, existential risks, military, nanotechnology, quantum physics

This #COVID19 is quite weird it just keeps evolving. In a weird way it is pushing evolution through our immune system. The only thing I know that is similar is like the flu or a bigger organism like cancer. Based on this information the virus just keeps evolving not dying off. Among the weird stuff it doesn’t effect cats or most animals or plants. Basically we either need a universal vaccine which is still being developed or we may need quantum radar to kill off the virus in our bodies when it comes out either that or foglet armor to not breathe it in like Ironman. I find it is just an odd virus as essentially it evolves so fast past even human beings abilities to fend it off even with suits it seems to spread so fast that it cannot be completely contained. From dogs that sniff it out it seems sorta everywhere. I know minor things like high dosages of vitamin c work with zinc and probiotics which was the first way to battle it when it didn’t become this whole pandemic because oddly enough it wasn’t a big deal in previous years because the 19th version of the virus. I know some things that kill it off are ultra violet and lysol as well as bleach. So it makes me think it is more a bioweapon where the universal vaccine would work. But oddly enough I am uncertain if it really dies off especially if it is airborne. If we can destroy the virus by reprogramming it to be sterile or innert or even for it to just kill itself off with crispr like we have done with mosquitoes to stop malaria. We can easily make new vaccines which is good but nearly every year or so there is an entirely new version. This isn’t new but it sorta is like the flu. But there are some theories that I sorta have where it seems to be near heat sources where it grows. Like my uncle who had the virus which we had him turn off electricity and also do vitamin c probiotics and zinc which did work. He ended up getting an antibody naturally this way. I personally got the vaccine and found that it does work but when the new delta version came out it did the same as the last one it sorta just randomly evolves for some reason even smells similar but oddly enough it still remains even after all the lysol. So to me it seems like a bioweapon that is self evolving which is we could use the mechanism to essentially evolve ourselves taking the components of it. If this was a nanobot swarm I would say it spreads from radio waves or something but this virus keeps spreading in odd ways like even from the sky. Which sorta makes me believe that it is sorta being manipulated maybe by a signal perhaps or it has its own program inside it. It reminds me of a Grey goo nanobot swarm that keeps evolving but the biological virus version. I mean it could actually be an exterrestial virus there was a meteorite that came around then and odd things that followed from the meteorite like dogs attacking people and cats attacking people even huge mountain lions. Which makes me think of a sorta an invasion of something. We need to maybe get the viruses input and output to find what it is going to do next. All and all seems odd because even other viruses don’t evolve or like fly or spread that fast. Ideally we should have cyborg nanobots running through Ironman in avengers endgame but so far our best better is treating it like the flu pumping out a new vaccine each year till we know a universal vaccine like using henreitta lacks immortal unlimited cell division cells like they did with polio. But till then we need to keep watching the virus as seems sorta more than it appears based on its original version.

Sakuu’s 3D printed solid state battery could be a boon for electric vehicles

Posted by in categories: information science, quantum physics, sustainability

How true Eric Klien?


Something to look forward to: Solid-state batteries are still nebulous outside of the lab. Still, automakers are scrambling to be the first in the race to build the first electric car to take advantage of the added energy density and better safety when compared to lithium-ion designs. To that end, they’re investing in companies like QuantumScape, Solid Power, and Sakuu to develop manufacturing techniques that either build on existing approaches or rely on new additive manufacturing technology.

Many-body thermodynamics on quantum computers via partition function zeros

Posted by in categories: computing, quantum physics

Partition functions are ubiquitous in physics: They are important in determining the thermodynamic properties of many-body systems and in understanding their phase transitions. As shown by Lee and Yang, analytically continuing the partition function to the complex plane allows us to obtain its zeros and thus the entire function. Moreover, the scaling and nature of these zeros can elucidate phase transitions. Here, we show how to find partition function zeros on noisy intermediate-scale trapped-ion quantum computers in a scalable manner, using the XXZ spin chain model as a prototype, and observe their transition from XY-like behavior to Ising-like behavior as a function of the anisotropy. While quantum computers cannot yet scale to the thermodynamic limit, our work provides a pathway to do so as hardware improves, allowing the future calculation of critical phenomena for systems beyond classical computing limits.

Interacting quantum systems exhibit complex phenomena including phase transitions to various ordered phases. The universal nature of critical phenomena reduces their description to determining only the transition temperature and the critical exponents. However, numerically calculating these quantities for systems in new universality classes is complicated because of critical slowing down, requiring increasing resources near the critical point. An alternative approach is to analytically continue the calculation of the partition function to the complex plane and determine its zeros.

The partition function is a positive function of multiple real parameters representing physical quantities such as temperature and applied fields. When the partition function is analytically continued in one of the respective parameters, its zeros show notable structure for a variety of models of interest. Lee and Yang (1, 2) studied the partition function zeros of Ising-like systems in the complex plane of the magnetic field h and found that, at the critical temperature (and in the thermodynamic limit), the loci of zeros pinch to the real axis. Alternatively, Fisher (3) studied the partition function zeros by making the inverse temperature β complex.

Levitation: Classic Magic Trick May Enable Quantum Computing

Posted by in categories: computing, particle physics, quantum physics

A new project will use the electric field in an accelerator cavity to try to levitate a tiny metallic particle, allowing it to store quantum information.

Quantum computing could solve problems that are difficult for traditional computer systems. It may seem like magic. One step toward achieving quantum computing even resembles a magician’s trick: levitation. A new project at the U.S. Department of Energy’s Thomas Jefferson National Accelerator Facility will attempt this trick by levitating a microscopic particle in a superconducting radiofrequency (SRF) cavity to observe quantum phenomena.

Typically at Jefferson Lab and other particle accelerator facilities, SRF cavities enable studies of the atom.

Two-dimensional supersolid quantum gas produced in the laboratory for the first time

Posted by in categories: particle physics, quantum physics

Quantum matter can be solid and fluid at the same time—a situation known as supersolidity. Researchers led by Francesca Ferlaino have now created for the first time this fascinating property along two dimensions. They now report in the journal Nature on the realization of supersolidity along two axes of an ultracold quantum gas. The experiment offers many possibilities for further investigation of this exotic state of matter.

Quantum gases are very well suited for investigating the microscopic consequences of interactions in matter. Today, scientists can precisely control individual particles in extremely cooled gas clouds in the laboratory, revealing phenomena that cannot be observed in the every-day world. For example, the in a Bose-Einstein condensate are completely delocalized. This means that the same atom exists at each point within the condensate at any given time. Two years ago, the research group led by Francesca Ferlaino from the Department of Experimental Physics at the University of Innsbruck and the Institute of Quantum Optics and Quantum Information at the Austrian Academy of Sciences in Innsbruck managed for the first time to generate supersolid states in ultracold quantum gases of magnetic atoms. The magnetic interaction causes the atoms to self-organize into droplets and arrange themselves in a regular pattern.

“Normally, you would think that each atom would be found in a specific droplet, with no way to get between them,” says Matthew Norcia of Francesca Ferlaino’s team. “However, in the supersolid state, each particle is delocalized across all the droplets, existing simultaneously in each droplet. So basically, you have a system with a series of high-density regions (the droplets) that all share the same delocalized atoms.” This bizarre formation enables effects such as frictionless flow despite the presence of spatial order (superfluidity).
