String Theory and Quantum Computing
String theory suggests that all elements of matter are made up of infinitesimal vibrating strings at various frequencies, which constitute different properties of, from our perspective, particles. As the strings vibrate, twist, and fold, various effects like gravity can be produced in many, tiny dimensions.
In Modern Physics, it seems that we can understand nearly all the mechanisms of how objects move or interact with one another from the scale in plank length from Quantum Mechanics to the realm of galaxy superclusters from the General Theory of Relativity. However, they do not tangle well together that the former theory only describes the motion of a massive object on a very large scale while the latter one only explains the probabilistic behavior of subatomic particles. It is hoped that both can be united by this possible "Theory of Everything" (probably quantum gravity).
dimension of the object depends on the views of the observer.
However, The bottleneck of resolving these conundrums seems wider after String Theory gained prominence in the late 1960s and '70s.
Humans are limited to experiencing higher dimensions of spacetime. For many decades, we have developed abstract mathematical models to verify the idea. It will be revolutionary if the dimensionality of spacetime can be verified as 9 or 10. It is the era where the advancement of technology may meet theoretical research when it comes to quantum computers. It is realized that the mathematical description string theorists use for black holes was identical to the mathematical description of quantum systems, like entanglement.
With the investigation of the black holes in string theory, entangled qubits could be the description of a certain class of black holes. If string theory could be applied to entanglement, it may also be possible to many-body-system. However, it may be due to the coincidence that mathematical structure in string theory is very similar to other physical phenomena. Then, it is proved that string theory is applicable to many areas.
