In the quantum world, particles are acting like wave movement. Or the particles like electrons have no straight core. The core of the particle is waving because the particle is carrying wave movement. The quantum boomerang means that when we are throwing particles to the quantum system. That particle would return like a boomerang. But when the particle is returning it takes data from another quantum system.
The boomerang effect is possible if the material or quantum system is non-perfect. There must be errors in the positions of atoms that the quantum boomerang can be possible. So the quantum systems that are forming the quantum boomerang must be disordered. When we are thinking the disordered systems there is the possibility that the quantum system that is used as the quantum computer is the neutron cloud of the nuclear reactor.
The neutrons can be superpositioned and entangled. And neutron radiation is easier to separate from other wavelengths. But the problem is how to get free neutrons? The answer is that nuclear reactors are full of free neutrons. The superposition of the neutrons in that neutron cloud could make by using lasers. Or some other electromagnetic radiation.
The quantum boomerang could be the particle that moves between quantum pillars between two quantum systems by using the "8"-shaped trajectory. The quantum pillar can be the extremely small pillar-looking magnetic field. Or it can be the particle.
Or it can be the combination of particle and magnetic field. There could be an electron or some other particle inside the pillar-looking quantum field. The electron would orbit around those pillars and interact with another electron inside that electromagnetic field. When the electricity of an electron is changing that thing causes the strength of the electromagnetic field where that stable particle changes. That thing can use to transmit data between two quantum systems.

The image above this is portraying a nuclear plant with two nuclear reactors. Those nuclear reactors are forming two quantum systems.
There is one interesting thing in quantum systems. The quantum systems might be in different places.
Or the quantum system can be at different energy states. When energy is pumped to the quantum system it will move to a higher energy level. When energy transmit ends that system will start to deliver energy until it reaches the same energy level with its environment.
So when the energy level of the system is changing the system is not the same anymore if there are no changes if we observe it from outside. Same way two virtually different quantum systems can be the same system. If they are connected with superpositioned particles.
So when we are thinking possibility that the energy of the quantum system decreases. That means the quantum system that is in lower energy level is a different system than it was in higher energy level. So the position of quantum systems can be at the place, time, and energy.
