Ultra-thin nanotubes and nano-technical lasers can boost a 6G network. And photonic- or non-electronic computer development. There are actually three main types of non-electric computers. 

A) Optical computers that use lasers or photons as data transporters. 

The first thing means that system transmits information using laser rays as a whole. When the laser shuts down, the value is zero. When the laser is on, the value is one. 

B) The photonic computer that uses quantum photon technology for storing and transmitting data. 

The second thing means. That. The system uses quantum technology, which packs information into single photons. 

C) Systems that transmit information in the form of radio or terahertz radiation.

Carbon nanotubes can absorb terahertz radiation. And that thing can boost the 6G technology. Additionally, it can boost high-power computing technology. The nanotube-based film. It can act as an insulator in high-speed data transportation. The system can transmit information through those nanotubes in the form of coherent radio. Or optical areas. The nano-sized lasers can send their laser beams through those nanotubes. 

Nanotube-based technology can also boost optical computing technology. Basically. An optical binary computer is similar to an electronic computer. The system shoots photons to the light meter. A certain light level is one. And below that level, light gives a value of zero. The binary photonic computer is sometimes mistakenly mixed with quantum computers. In quantum computers, there is more than one value. But in optical binary computers, there are only two values, 1 and 0. 

There are two ways. To make an optical or photonic computer. 

1) Fully photonic computer. There, the microchips and all components use photonic data transportation systems. 

2) Semi-optical systems. There are only wires that connect microchips. Or integrated microcircuits are replaced by optical data transportation tools. And internal data transportation or data processing in those microcircuits. Happens by using the electric method. In this case, the optical computer uses nano-scale lasers to transmit data. And nano-sized photovoltaic cells receive that information. 

But the problem with optical computers is the system that transmits information. Lasers are effective tools, but they need power. Theoretically, a photonic- or optical computer is more energy-efficient. Than the electric computers. The main problem is that. The photonic computers are not a useful solution. To computer energy problems. If the energy that the photonic system saves. Goes to high-performance cooling systems. But nanotechnology can be the answer. To that problem. Nano-sized lasers are much easier to cool than full-size lasers. 

Another answer could be the so-called wireless computer. The system can use radio waves. Or. Terahertz rays. The system must protect that information from eavesdropping and outside effects. In that system. The system uses nano-sized radio transmitters to transmit data. In the computer. And that makes nanotubes useful tools for. Those kinds of systems.
