Quantum tunneling gave the Nobel prize.

"A simulation of a wave packet incident on a potential barrier. In relative units, the barrier energy is 20, greater than the mean wave packet energy of 14. A portion of the wave packet passes through the barrier." (ScitechDaily,

Quantum tunneling gave the Nobel Prize. To people who researched it. Quantum tunneling is one of the most impressive phenomena, which can make it possible to teleport information or, someday, even humans. 

The phenomenon means that a particle. Like an electron or a photon. Can travel through the potential barrier without causing visible damage. Wikipedia describes quantum tunneling like this: “In physics, quantum tunnelling, barrier penetration, or simply tunnelling is a quantum mechanical phenomenon in which an object, such as an electron or atom, passes through a potential energy barrier that, according to classical mechanics, should not be passable due to the object not having sufficient energy to pass or surmount the barrier.” (Wikipedia, Quantum tunneling) 

Quantum tunneling happens when two potential barriers interact. The particle that should tunnel through the wall travels in the quantum shadow or quantum channel. The edge of that channel pushes the vertical potential field away from its route. And if the vertical potential wall cannot crush that channel, the channel allows particles to travel through it without touching the vertical potential wall. 

The tunneling effect makes it possible. To create new types of sensors and other tools. Theoretically is possible to tunnel even humans through the walls. The tunneling effect forms. When an electron or some other particle is in the laser beam. Then the electromagnetic shadow pulls the electron to the potential wall. The potential barrier. That keeps the electron away from the potential wall. That it should pass. It is at the edge of the electromagnetic shadow, or quantum channel. 

One of the reasons why it's very hard to transport complex systems through the wall is that. The system must raise the energy level in all particles. In the system simultaneously. If there is an internal shockwave. That forms when an energy wave travels to the front of the system. That thing destroys the system. The teleportation requires. All particles in the system. Take the energy load at the same moment. And then the teleportation system. Must keep the transportable objects in their form. The system must create a quantum channel. That pulls the object through it.
