Quantum radar. It can be two-layer graphene. The system puts quantum entanglement between particles that are locked in those squares. The system should use particle pairs. In transmitting particle pairs. The outer particle is at a lower energy level. That particle transmits signals. And in receiving a particle pair, the outer particle is in the lower energy size, which allows it to transport information into the system. That kind of quantum dot-based technology can break the stealth material. In that system, the frame spins, and that makes it possible to create. The scanning Doppler radar.  

In some other versions, the system uses a cut nanotube. The nanotube forms the crown-shaped structure. And in the middle of the nanotube is the antenna that transmits. The nanotube spins around that antenna. And that allows it to create the nanotechnical Doppler radar. The main problem. With Doppler radars. The antenna must move. 

So. That it can work right. The reason for that is this. The same antenna cannot transmit. And receive at the same time. The moving antenna makes it possible. That. The angle of the receiving antenna changes. This makes it possible. To determine the location of the point where signals reflect. Normally, the radar has a light parabolic shape, which makes it possible to determine the distance to objects. Another version. It is easier to use the change of frequency when the object comes straight to the radar.

Those transmitter-receiver antenna pairs can have an adjustable angle. This allows them to measure distance to the target. Very accurately. In those cases, the other antennas can send plus, and the other transmitter antennas can send A minus mark. Radio signals. Those signals form an electric arc to the target. 

This is important when something comes. Straight ahead to radar. The quantum dot-based radar can also use moving structures. 

Sometimes it’s discussed. About the possibility of using things like helium atoms as quantum radars. The atom’s core acts as a transmitter. And electrons act as a receiver. The system can also use things like excitons. The hole acts as a receiver. And the electron. Which orbits the hole act as a transmitter. Those exciton-based systems are already in use. 

In the laser-based systems. They can use the one-pixel scanner. And the nano-lasers. Those one-pixel systems can be in a frame that spins around the laser. 

The new nanotechnical lasers can act as pairs with the pixels that can receive the reflection. The laser. It can have a frame. Those receiving pixels are in that frame. As a circle. This makes it possible to create optical lidar (”laser radar”) that can scan surfaces and operate over longer distances.

Excitons and light form new quantum states.

“Physicists have long wondered what happens when a superfluid is cooled even further, and now, experiments in bilayer graphene hint at an unexpected answer. Credit: SciTechDaily.com” (ScitechDaily,Physicists Watch a Superfluid Freeze, Revealing a Strange New Quantum State of Matter)

The new form of quantum state of matter is found in bilayer graphene. The bilayer graphene is the thing. That can make a superfluid freeze or stop moving. This means that the graphene is covered by an icy superfluid. And that uncovered strange new quantum behavior in that thing. 

Researchers found an unexpected relationship. Between the density of the quasiparticles and the temperature. At high density, excitons behaved like a superfluid, but as their density decreased, they stopped moving and became insulators. When the temperature decreased, superfluidity returned. 

Those systems can revolutionize.  Quantum computing technology. The laser systems can be used to adjust that transition. 

This phenomenon can be used in superconducting miniature electronics. The ability to control insulation. And electric conductivity. It is an important thing for the gates and switches in the small superconducting microchips. 

The system can use a laser as a thermal pump. The laser can be used to adjust the energy flow in the graphene, so that it transports as much energy away from the fluid as possible. The superfluid is between those graphene layers. And that helps to control it.

“For all the theory and debate, the most famous candidate, helium, has not provided a definitive, natural example of a superfluid turning into a supersolid. Researchers have built supersolid-like systems in the atomic, molecular, and optical (AMO) sub-branch of physics, but those demonstrations typically rely on lasers and optical components to impose a repeating structure. This creates what is known as a periodic trap that encourages the fluid into a crystal-like pattern, a bit like Jello confined in an ice cube tray.” (ScitechDaily, Physicists Watch a Superfluid Freeze, Revealing a Strange New Quantum State of Matter)

“Controlling a superfluid in a 2D material is an exciting prospect—compared to helium, for example, excitons are thousands of times lighter, so they could potentially form quantum states such as superfluids and supersolids at much higher temperatures. The future of supersolids remains to be realized, but there is now solid evidence that 2D materials will help researchers understand this enigmatic quantum phase.” (ScitechDaily, Physicists Watch a Superfluid Freeze, Revealing a Strange New Quantum State of Matter)

Another thing is that. The light can. Have quantum ability. Which allows it. To control things. Like the magnetic field. The ability to force atoms at a very low temperature into straight lines can make it possible to create a situation where the magnetic fields travel through matter. This thing makes it possible.  To create quantum levitation, or the so-called Meissner effect. But the Meissner effect can also make it possible. 

To create systems that allow light to travel through the system. If there are no fields that can cause reflection. The system turns invisible to those wavelengths.  The reason for that is this. Without reflection, the energy or wave movements cannot reach the observer. That turns matter into a ghost. 

But the ability to control magnetism makes it possible. To create new fundamental material layers. Those layers can form the grooves by pulling the layer that reacts to the magnet down. And when those grooves are not necessary, the magnets can be shut down. 

There is also a possibility that the layer is made using tiny magnets. Those nano-scale magnets can be in the nanotubes. And. The system can turn them by using light. The ability to adjust their polarity. Makes it possible. To switch the polarity in the layer. 

These types of systems could also turn. The polarity of the magnets. Oppositely. This means that light turns those poles upside down. And that makes it possible to change the polarity of the layer.

Portable nuclear reactors can revolutionize technology.

Portable nuclear technology is the tool. That offers new energy solutions for new types of systems. The problem is that the military. And other types of infrastructure. Require lots of energy. 

New AI-based systems. Like adapting camouflage. And especially drones are problematic things. The AI requires lots of energy, and in the same way. Defense against drone swarms requires directed energy weapons. Those directed energy weapons require electricity. The Shahed-136-type drones can give. All platforms have an attack range of about 1000 kilometers. 

The small drone with a hollow warhead. It can cause lethal damage. If. It hits the nuclear submarines. Small nuclear systems. Can offer new types of abilities to small systems. Plutonium batteries offer a small drone. It uses an electric engine and a propeller. Unlimited. Operational range. Those drones can be airborne, underwater unmanned vehicles (UUV), and surface drones. 

A portable nuclear reactor fits in a truck. “'ZEUS' NANO Nuclear Energy's Portable and On-Demand Advanced Nuclear Micro Reactor Design”(Yahoo.com)

Portable, or miniature nuclear reactors. It can give a new capacity. To a small submarine. Like the Swedish A26 (The Blekinge) class. The Swedish A26 is a silent diesel-electric submarine that uses air-independent diesel-electric engines. Those submarines are shown to be effective when they could damage or even destroy the U.S fleet carrier during a naval drill. That submarine can be even more effective. If. It can have nuclear engine ability. 

That so-called micro reactors can offer. Micro-sized nuclear reactors. Are planned. To use as a portable energy solution for military operations and anti-drone systems. But they can also give. New abilities in all types of logistics. From trucks and other vehicles. Those systems can offer aircraft and ships almost unlimited operational range. Small-sized systems. That offers electricity. And heat to limited areas. Can make the networked energy solutions possible also in civil infrastructure.
