or is there in fact a physical reality that exists independently from our perceptions?

That is a mis-statement. There is certainly an objective reality; on a macroscopic scale, you can determine it easily enough. Quantum theory shows that it is not possible to measure both the momentum and position of a particle with arbitrarily high precision; the product of the uncertainties in the two measurements can never be less than a certain small constant called Planck's constant. This is of crucial importance in atomic physics; it is completely unimportant in everyday life.

There are mathematical models that allow for alternative descriptions of things. You, personally, can be described as a wave. Having done that, if you and all your friends who weigh the same walk at the same speed through parallel turnstiles at the ball park, it can be predicted what sort of interference pattern will form on the other side. But, it just a model that allows the mathematics systems of some other discipline to be used. I, personally, believe that that cute blond at the bus stop is not a wave or a string. I like the physical model for that situation.

Quantum theory does not say that nothing is real.

Quantum theory is just a theory.It only describe what is suppose to tell.

Well, I'm real.
