Photonic time crystals can enhance communication and laser technology.

Photonic time crystals offer nanotechnical breakthroughs in photonic communication and quantum technologies. 

Photonic time crystals can be the next-generation tools for miniature maser systems. In those systems, the photonic time crystals are put around the miniature tube, and the leading crystal that sends wave movement through that energy field is at the bottom of the (nano)tube. This system looks and acts like a small-size acoustic hailing device but it acts like a small-size maser. If that system is used in large-scale systems that gives them more accuracy than is seen ever before. 

These kinds of systems can use in the next-generation quantum computers to determine the state of the artificial neurons. This kind of photonic-nanotechnical hybrid brain can be the next step to highly advanced quantum systems. Like a nanotechnical brain that learns like the human brain. The photonic time crystals are the tools that will revolutionize technology. 

They offer a good system for making the next-generation stealth systems. In those systems the photonic time crystals are conducting photons that impact them sideways. And that thing decreases the ability to see that object also in visible light.

Spectrum: every color in the spectrum formed, when elements send radiation with their unique frequency. That thing can also use for making the difference between Qubit's states. (https://www.astro.rug.nl/~ndouglas/teaching/ObservingTechniques/spectroscopy.html)


This thing allows the creation of artificial neurons. 

For the first time, researchers connected two quantum digits. The system used a vacuum chamber there is the microsurface fabricated trap. That ability makes it possible to transport information between two complicated quantum systems. 

In some theoretical versions, the data transportation between two complicated systems happens by using graphene layers there are different element atoms in the graphene network. Then those atoms act like the transmitter-receiver pairs in the human neurons. The reason for that is. Every single element has its oscillating frequency that benefits spectroscopy. 

In science, astronomers use those frequencies use determining the relations of the elements in stars. But they can also use for determining or separate different states of qubits.  

And that system bases technology where those atoms are resonating with each other. The problem with data transportation between complicated quantum systems is how to separate the oscillation of certain states of qubits. The system can use miniature maser systems to oscillate certain atoms. 

That hangs in the graphene network. And then that oscillation transfers information to similar atoms in the receiver. So when the system stresses the Crypton atom, it causes resonance at the receiver's Crypton atom. And that thing can make the new type of quantum computers possible.

Chinese innovations and space lasers are interesting combinations.

Above: "Tiangong is China's operational space station located in low Earth orbit. (Image credit: Alejomiranda via Getty Images)" (Scpace.com, China's space station, Tiangong: A complete guide) Chinese are close to making nuclear-powered spacecraft.  Almost every day, we can read about Chinese technical advances. So are, the Chinese more innovative than Western people? Or is there some kind of difference in culture and morale between Western and Chinese societies? The Chinese superiority in hypersonic technology is one of the things that tells something about the Chinese way of making things.  In China, the mission means. And the only thing that means is mission. That means that things like budgets and safety orders are far different from Western standards. If some project serves the Chinese communist party and PLA (People's Liberation Army) that guarantees unlimited resources for those projects. Chinese authorities must not care about the public opinion.  If we th

Iron Dome is one of the most effective air defense systems.

The Iron Dome is a missile defense system whose missiles operate with highly sophisticated and effective artificial intelligence. The power of this missile defense base is in selective fire. The system calculates the incoming missile's trajectory. And it shoots only missiles that will hit the inhabited area. The system saves missiles and focuses defense on areas that mean something. The system shares the incoming missiles in, maybe two groups. Another is harmless and another is harmful.  Things like killer drones are also problematic because their trajectories are harder to calculate than ballistic missiles. The thing that makes drones dangerous is that they can make masks for ballistic missiles. And even if those drones are slow, all of them must be shot down.  The thing is that the cooperation between drone swarms and ballistic missiles is the next danger in conflict areas. In the film, you can see how drones make light images of the skies. The killer drones can also carry LED li

The innovative shield that protects OSIRIS-APEX can also protect the new hypersonic aircraft.

"NASA’s OSIRIS-APEX spacecraft successfully completed its closest solar pass, protected by innovative engineering solutions and showing improvements in onboard instruments. Credit: NASA’s Goddard Space Flight Center/CI Lab" (ScitechDaily, Innovative Engineering Shields NASA’s OSIRIS-APEX During Close Encounter With the Sun) The OSIRIS-APEX probe travels close to the sun. The mission plan is to research the sun. And especially find things that can warn about solar storms. Solar storms are things that can danger satellites at the Earth orbiter. And the purpose of OSIRIS-APEX is to find the method of how to predict those solar storms. Another thing is that the OSIRIS-APEX tests the systems and materials that protect this probe against heat and plasma impacts.  The same technology. The researchers created for OSIRIS-APEX can used in the materials and structures. That protects satellites against nuclear explosions. That means this kind of system delivers information on how to prot
