The term quantum materials means materials. That uses some quantum features to make new abilities for them. Things like graphene have their features because that material is a 2D carbon structure with a monoatomic form. There is no other than carbon atoms. But then we can see, that only one thing like one oxygen atom can destroy features of those materials. That requires extremely high-level purity.
The ability to control the point where energy travels through materials like graphene makes interesting visions to think of things like zero-point energy. If the energy flows through the quantum whirl that goes through the graphene it will not touch the whirl itself. That thing creates the quantum thermal pump. If that system can make a stable cold quantum spot in the graphene or some other material that thing acts as the electromagnetic cold spot that makes energy travel into it.
Quantum metal's strange behavior in low temperatures makes them test the laws and borders of physics. The low temperature makes the metals superconducting. But the problem is. How those materials lose their resistance. In some models, the metal's atoms will turn under one common quantum field. And that field denies the formation of Hall effect or Hall fields.
Electricity doesn't exactly travel in wires. It travels on the shell of wire. Or at the quantum fields above the wire. If the quantum fields at the shell of the wire turn superconducting. Superconduction is only one thing in quantum technology. There are many ways in which to system can benefit from the ability to control the quantum fields around them.
The quantum system. That can stretch quantum fields around the quantum materials. Can turn the layer invisible to the radar infrared and even the human eye. That thing means that the material or its quantum field can pull all energy that impacts it into it and that denies the reflection.
The electron cloud can also pull energy or quantum noise into it. The problem is that the same effect. That protects the quantum systems from non-controlled effects that can turn into effects. That destroys the quantum field. If some outside particle impacts things like quantum entanglement that is the end of the calculation in that time. Quantum entanglements are interesting tools for controlling energy flows in materials.
But controlling them is a very hard process. Another thing is magnetic impurity. The impurity in material causes the impurity in magnetic fields. And one thing. That makes the impurity in the magnetic field some different atoms in a structure that should be monoatomic.
"In physics, the Kondo effect describes the scattering of conduction electrons in a metal due to magnetic impurities, resulting in a characteristic change i.e. a minimum in electrical resistivity with temperature." (Wikipedia, Kondo effect)
The thing is that there are some kinds of things like quantum dots that can create turbulence in the quantum system. The quantum dot can form accidentally when there is some higher or lower energy point in the quantum field.
The most powerful quantum dots in the universe are the black holes. The controlled quantum dots are effective tools The quantum dots can make it possible to transport energy out from the quantum field. The quantum dot can precisely and highly accurately pull energy out from the quantum field.
