Quantum dot-based technology can be a new tool against stealth technology.

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. 

“DTU researchers have invented a nanolaser constructed in a semiconductor membrane that causes electrons and light to gather in a small area (blue shadow). By using light instead of electrical signals on microchips, data speed can be increased and energy loss reduced.

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.
