The image above this text shows how laser stresses 2D tantalum disulfide crystal. Researchers are found new mysterious hidden quantum phrases in the tantalum disulfide. And the question is can this kind of quantum phrase exist in other materials like graphene? Or is that quantum phrase existed only in the metallic atoms? (1)
There is the possibility that the laser impulses can also use as a press that will remove the higher level of carbon atoms from the graphite and transforms it into graphene. The lasers can be the ultimate tools for creating new 2D materials that are needed in a new type of electronics laser rays will be shot through the graphene layers.
In some of the most modern systems, the information will transfer to those laser rays by stressing graphite by using energy. That system can give energy stress can by using masers or lasers with different wavelengths. The system is two graphene layers where laser travels between those layers.
The researchers stressed tantalum disulfide by using laser light for testing the metastability. The metastability is the key element in the quantum computer. The system must have a different energy level than its environment so that the quantum computer can separate qubits from the environment. The image above shows how the laser system stresses the tantalum disulfide with energy. And that thing makes it possible to observe metastability in 2D quantum systems.
If the quantum computer can maintain the quantum metastability long time. It would not re-adjust itself so often. "In chemistry and physics, metastability denotes an intermediate energetic state within a dynamical system other than the system's state of least energy". (Wikipedia, Metastability). Things like avalanches are a good example of the metastable system. They are locked to a higher energy level until something removes that lock and allows energy transfer out from the system.
Metastability in the tantalum disulfide is helping to understand the birth and evolution in the hidden quantum phase. Metastability means the case or conditions where a physical system (quantum etc.) can stay longer at an energy level that is not the lowest possible.
The things like avalanches and rolling balls are introduced as an example of metastability in the systems. In those cases, the system takes energy from outside like an avalanche that falls from mountains. When the slope ends. The system will reach all its extra energy to the environment.
Opposite metastability means that the energy level in the system is lower than its environment. And one example of this thing is the ice bite that is carried in the house. The opposite metastability means that the temperature of that ice is lower until energy flows to it from the environment.
