Intel Corporation, together with scientists from the University of California in Berkeley, plans to go beyond the existing transistor technologies in order to pave the way to a new type of computer memory and logic schemes using progressive quantum materials.
A study was published yesterday with a description of the transformation method with respect to new types of materials (multiferroers and topological materials) into computational and storage devices that will consume 10-100 times less energy, and increase the efficiency of microprocessors. Magnetoelectric spin orbital (meso) devices will be able to perform five times more logical operations per unit space, compared with existing semiconductors.
In Meso devices, binary bits are moving from top to bottom magnetic spin states in the multiferroic. Scientists argue that they reduced the voltage required to switch between 0 and 1 to 500 million, and in the future it is possible to achieve an indicator of 100 mV. This will reduce the power consumption of future transistors about 30 times.

Multiferots are materials whose atoms have more than one «collective state». Meso is based on one of such materials with unique quantum properties consisting of bismuth, iron and oxygen (BIFEO3), which is simultaneously both magnetic and ferroelectric. These two characteristics are associated and interdependent. Driving an electric field, you can change the magnetic state.
New devices will stimulate technologies that require significant computing power with low energy consumption. For example, unmanned cars and flying devices, internet devices of things, artificial intelligence systems.
Researchers predict that the rapid development of the computer chip industry will increase the share of their energy consumption from 3% to 20%. Therefore, they are looking for revolutionary, not evolutionary solutions to the issue, and believe that Meso will eventually replace the omnipresent semiconductor transistors.
In parallel with bit, quantum computers develop. Recently developed the first
