Berkley scientists have come up with a new method of encryption that involves sliding monoatomic layers of tungsten ditelluride.
In this case an odd number of mono-atomic layers sliding laterally in relationship to an even number can be used to represent 1 and 0. It is essentially a new form of nanotechnology that is mix of a 2D material and quantum metamaterial.
“Hence, a material platform like this works perfectly for memory, with separate “read” and “write” operation. By using the new data storage technique, the energy consumption can be reduced more than 100 times when compared to the conventional technique.”
The new material could lead to a technological revolution.
“When compared to the prevalent non-volatile (NVW) memory, the novel material platform is predicted to reduce energy cost by three orders of magnitude and boost storage speed by two orders of magnitude.”
Instead of turning on an electrical current within the device the researchers simply apply a vertical electric field and the odd number layers slide across, they can then shift to another field in order to move them back and forth – through this layered churning process they can encrypt a programming language within the matter itself.
The team used quantum geometry, another term for Berry Curvature to read out the information. What’s interesting about quantum geometry is that it has been used to explain the inner workings of gravity as well.
