The new types of computers use the electron's, and electric field's charge states to make ultra-fast and energy-efficient supercomputers. Things like ultra-fast electron microscopes can observe how electric charges behave in electrons. And those systems can be the next-generation tools that can observe internal actions in quantum- and binary computers. That thing allows for a decrease in energy use.
The problem with supercomputers is the energy. That those systems require. Another problem is the temperature that the resistance causes. Temperature is the thing that increases the energy loss. And that thing makes supercomputers untrusted. The resistance causes errors in data, that travel in wires.
To minimize resistance is possible to create superconducting systems. But the problem is how to control electricity in those ultra-cold systems. And those systems require electricity in their supercoolers.
The computer researchers must find some other way to transport information in the system. The system can make power fields that can act as the wire. The new research introduces a method that can harness charge density waves for the new kinds of computing systems.

Researchers in DOE's Argonne laboratory created a material called 1T-TaS2 which is interesting because that material can used to manipulate the state of the charge density waves using electricity.
"First, the charge density waves melted in response to the heat generated by the injected current rather than the charge current itself, even during nanosecond pulses. Second, the electrical pulses induced drum-like vibrations across the material, which wobbled the waves’ arrangement".

The ultra-fast electron microscopes can also be a base for equipment. That can adjust the electron's or atomic-scale objects' energy levels. That ability makes it possible to create a quantum neural network where the electromagnetic fields form a structure that behaves like neurons.
The idea is that the system can form situations that electric fields. And ultra-fast states in electrons can form EM structures that look and behave like neurons. The electrons are the most ideal things there that kind of system can input energy. And then the power field forms around the electron.
The idea is that the system transmits energy to the electron or some other very small structure. The electric field looks like an amoeba. Information can travel between those electric fields. In some ideas, the ring-shaped standing electromagnetic field can make superposition and entanglement between those fields. That kind of field-based quantum computers might be the next-generation tools.
