Strange bird-like behavior unveils new possibilities in quantum systems.

Moving atoms (or ions) act like birds in the new ferromagnetic phenomenon. The first moving atom pulls the electromagnetic waves behind it, and those waves pull atoms to follow the leader particle. When electromagnetic waves hit the leading atoms, they create electromagnetic waves with hills and ditches. 

That phenomenon looks like a bird flock or ship that moves on the sea. That leading particle follows wave movement behind it. And the distance of the waves is always the same. The electromagnetic ditches between those hills can pull other atoms into that wave movement. 

The forward-moving movement can be virtual. If energy sources like a light beam illuminate the leading atom from the forward, that thing can create a similar effect. The electromagnetic waves travel out from the atom. If the electromagnetic field travels in an opposite direction than this wave movement it can create extremely low-energy ditches and high-energy hills. 

And a quantum computer could use that thing to trap particles between those waves and put them into the quantum entanglement. That can be the new way to transport information

More details

In diagram,  the flat conductor possesses a negative charge on the top (symbolized by the blue color) and a positive charge on the bottom (red color). In B and C, the direction of the electrical and the magnetic fields are changed respectively which switches the polarity of the charges around. In D, both fields change direction simultaneously which results in the same polarity as in diagram A. electrons flat conductor, which serves as a hall element (hall effect sensor) magnet magnetic field power source (Wikipedia, Hall effect)

Hall-effect and quantum computing. 

"The Hall effect is the production of a potential difference (the Hall voltage) across an electrical conductor that is transverse to an electric current in the conductor and to an applied magnetic field perpendicular to the current. It was discovered by Edwin Hall in 1879" (Wikipedia, Hall effect)

"The Hall coefficient is defined as the ratio of the induced electric field to the product of the current density and the applied magnetic field (Hall field). It is a characteristic of the material from which the conductor is made, since its value depends on the type, number, and properties of the charge carriers that constitute the current." (Wikipedia, Hall effect)

The system traps particles in the Hall fields or standing waves. And information travels between those hovering particles. That thing can make photonic and acoustic crystals suitable for the base of quantum computers.

But the Hall effect can also used for the same purpose in the regular wires or nanotubes. Even if the fullerene nanotubes cannot create those trapping fields, the metallic atoms may connected with those carbon atoms, and that gives new properties for those tubes. 

Sometimes people say that only superconducting materials can fit into quantum computers. However, there is a possibility to use non-superconducting materials in quantum computers. In that model, the system traps the particles into the Hall field. So, information travels outside the wire between superpositioned and entangled particles that hover in series at the hall field. 

Then the system can create the superposition and entanglement between particles that hover in the Hall field. The problem is how to stabilize the system. it requires low temperatures and a stable environment. The Hall field can be created into the nanotubes, and then the system traps the particle, in that field.
