yes, it is the best tested theory there is. Theoretical and Experimental values agree to about 9 digits of accuracy.
Quantum theory has been tested and theoretical and experimental values have been found to agree to more digits of precision than in any other theory tested against reality!
The same reason any other theory is accepted: it explains known observations and it makes predictions that are testable by experiment (and prove correct when tested).

Nope. They keep the theory the way it is. No one changes it. Usually, when scientist have tested the theory and find out something new, they create a new theory instead of changing the first one.
The original founder of quantum theory was Max Plank. The basic theory has been improved upon many times but there hasn't been a 'Modern Quantum Theory' that replaces the old.
Einstein's laws, particularly his theory of relativity, have been extensively tested and confirmed through numerous experiments and observations. They are considered highly valid and form the basis of modern physics. However, they may break down in extreme conditions such as near singularities or at the quantum level, where the theory of general relativity and quantum mechanics are not yet fully reconciled.
Quantum information theory (QIT) is a mathematical framework that describes information processing tasks with quantum systems. However, like any scientific theory, it is subject to experimental verification and refinement. While QIT has been successful in predicting and explaining many quantum phenomena, it is not "always correct" and is continually being developed and tested through experiments.
