Here’s A physicist’s defense of reality, despite quantum physics:
He explains why Eddington’s solid table really IS solid, even if, at the highest resolution, it is mostly empty space…
So the space isn’t “empty” after all; it is occupied by the probabilities of electrons operating according to the laws of quantum physics (often called quantum mechanics or QM). The particles are very much there, though not, perhaps, in the way we are accustomed to think.
There’s another aspect to this question as well. There is no reason to consider our perceptions to be illusions unless there is a more correct perception that we could have at the same level of resolution.
Consider, for example, a decoy duck, floating in the water. The decoy is not an illusion on account of the fact that its atomic composition is not perceived by our senses. It is an illusion because — at a distance — we believe it to be a live duck. That is, there really is such a thing as a live duck and the decoy looks like a live duck without being one.News, “A PHYSICIST’S DEFENSE OF REALITY, DESPITE QUANTUM PHYSICS” at Mind Matters News

Can a materialist consciousness theory survive quantum mechanics? Quantum mechanics requires that the observer be part of the measurement; thus quantum measurements must include consciousness. If quantum measurements must include consciousness, the dualists are correct, says philosopher Angus Menuge: Consciousness exists in its own right.
In quantum physics, “reality” really is what we choose to observe. Physicist Bruce Gordon argues that idealist philosophy is the best way to make sense of the puzzling world of quantum physics. The quantum eraser experiment shows that there is no reality independent of measurement at the microphysical level. It is created by the measurement itself.
