Experimentally improving the efficiency of matter transmission, there are three directions that come to mind.
One is to start from the end point of transmission, which is a closed space with a stable light source and materials.
Another is to start with the transmission channel. Previous experiments have been done, proving that the channel can increase the transmission efficiency of atoms and molecules and reduce the transmission efficiency of tiny particles, but it has not increased the overall transmission efficiency.
This is also a significant finding, proving that increasing the channel is still very meaningful.
Finally, it is to start from the transmission endpoint, which is the area where space does not exist. However, this makes it challenging to proceed, as even space has already ceased to exist. At most, increasing the compression rate could expand the size of the area where space does not exist.
