NASA (Lockheed Martin Skunk Works) X-59 QeSST (Quiet Supersonic Transportation) is the cutting-edge prototype for the next generation of military and civil aircraft.

The NASA (Lockheed Martin Skunk Works)X-59 QeSST (Quiet Supersonic Transportation) is one of the most interesting and awesome ideas in aviation. That system allows high-speed flying with very low noise. And the idea of this demonstrator is that the shape of the aircraft is turning the supersonic cone to the extremely thin mode, which makes it weaker before the pressure wave reaches the ground. 

The idea of this system is that the air pressure is traveling to the ground as long as possible. That means that the bottom of the aircraft might be straight. 

And that thing turns the sound, what the aircraft is creating lower. Also, the exhaust gas of the engine can surround by using coherent sound waves. That is closing the exhaust gas in the sound channel. If the observer is standing outside the sound channel that person cannot even hear the sound. The purpose of the X-59 is to low the noise of the sonic boom and jet engines lower. 

Maybe the QeSST technology is not very impressive, but when it is connected to the new super- and hypersonic STEALTH aircraft, helicopters, and missiles, that thing turns extremely powerful. The technology allows creating the fast transportations, deep penetrating aircraft, missiles, and drones, that are very hard to detect. The thing is that this kind of technology is only one part of an engineering masterpiece called Stealth. 

The new intelligent materials are waving, and the radars cannot touch a certain point. Or they can benefit Klein paradox, where the radiation can travel through the material (potential wall or transparent wall) without resistance. The potential wall can be physical or it can be an energy field. So there is the possibility to make material, which limit is transparent. This means the material can let radiation go through the material without causing interaction or energy would not transfer to that limit. 

Intelligent materials like extremely long carbon-fiber strings or molecules are allowing to create the new type of stealth structures. That structure turns to curves. When it is curving by magnets. That thing allows making the structure, which waving is active. So the material is forming the moving waves like water. And that thing makes it very hard to hack that kind of intelligent material. 

The wavelength and point of the tops of those curving molecules can adjust very sharply, and that means the system is very hard to break. Another thing that quantum stealth can benefit from is the Klein paradox, where radiation can travel through the material without resistance. 

That thing allows making the aircraft where the radar impulses travel straight through the aircraft without giving an echo for the transmitting radar. The Klein paradox allows also making the materials that are invisible to the human eye. The material that can pass the radiation through it without resistance can make laser weapons useless.
