"Scientists have uncovered how tiny magnetic waves can produce electric signals inside materials, potentially transforming computing efficiency. University of Delaware engineers have shown that magnetic waves called magnons can create electric signals, bridging two key forces in computing. Their work points toward chips that operate faster and more efficiently by eliminating wasted energy. Credit: Shutterstock.

The discovery is named magnon, or actually. It is the magnon's ability to transmit magnetic waves in structures. “A magnon is a quasiparticle, a collective excitation of the spin structure of an electron in a crystal lattice. In the equivalent wave picture of quantum mechanics, a magnon can be viewed as a quantized spin wave. Magnons carry a fixed amount of energy and lattice momentum, and are spin-1, indicating they obey boson behavior.” (Wikipedia, Magnon)
The ability to transmit information between atoms, or atomic-scale quantum dots, requires methods that don’t disturb the material. The magnetic wave that travels between atoms doesn’t cause as much heat as regular electric flows. Magnetic waves don’t oscillate matter as much as electricity. And that makes it possible to create smaller and smaller microchips. One of the problems with computers is heat. Every time electricity travels through a wire, it faces resistance. The thing. That causes resistance. This is the so-called Hall effect.
There is a small part of electricity that jumps backward from atoms and forms a standing wave. So, for jumping through that standing wave or potential barrier, the system must pump more and more energy into the wave. The standing wave acts like a dam. That collects energy behind it. And that effect continues until energy can travel over that dam. This is why wires should be kept as short as possible. In the small microchips. Even a small anomaly. Has a big effect.
The problem with superconductors is that the superconducting microchip cannot control electric flow in the same way as a semiconductor. In semiconductor. Electric impulses control the electrical flow by adjusting the resistance in the semiconductor. The semiconductor is an insulator and a conductor. At the same time. That ability is needed at the gate. When a semiconductor is in the state of an insulator. That point will not let electricity travel through it. That means the gate is closed. And when the semiconductor is in the conductor state, the gate is open. And electricity can travel through it. And when the gate is closed, the state in the wire is zero. When the gate is open, the state in the wire is one.
In superconducting microchips, the laser can be used to make those gates. The laser system can heat the superconducting material. And that removes superconductivity. The laser system forms a gate in the superconductor. The problem with those systems is that they need very low energy levels. If the energy level in the impulse is too high. That means energy travels over that thermal gate. The superconducting computer. It can be the answer to compact AI systems. Those microchips make it possible to create laptops and even pocket-sized systems. That can have a calculating capacity. That beats some of the supercomputers. Those systems require pocket-sized superconducting technology. And maybe. Nano-sized pressure and cooling systems can turn them into reality.
