Has quantum computing debunked the law of noncontradiction?

[Abrosz]

The problem lies in using macro level ideas, like particles and waves, to describe something that is both. The model is inadequate.

This is it. The mathematics of quantum physics allows us to make accurate predictions. Th fact that they cannot be “visualized” or translated into traditional, macro-world categories is not important. No one can visualize a 4-dimentitonal (or any n-dimensional) space, but that concept is perfectly usable in mathematics. Has anyone ever used a tesseract?

You are conflating macro level concepts with quantum objects and then saying there is a real contradiction. But there is no contradiction in the metaphysical sense of the word. A cat cannot exist and not exist at the same time. A wave particle duality cannot exist and not exist at the same time. The principle of non-contradiction applies to every level of reality. Just because you have found a situation where a thing can behave in a way that would not be possible at a macro scale is not evidence that a real contradiction has occurred. A non-binary system is not necessarily one that defies logic. It simply depends on the nature of the system. We know that a square circle is impossible because it is meaningless, but that might not be true for a different kind of system dealing with a different kind of nature to squares and circles. You are making a metaphysical inference that isn’t justified by the scientific method.

You shouldn’t be thinking that the law of non-contradiction is broken. You should be thinking how do we explain this given the law of non-contradiction. The latter is harder, but you are more likely to get to the real truth.

In otherwords you are jumping to conclusions.

The inadequacy of models is basic to quantum mechanics, which is why it brings into question the noncontradiction principle. We are used to thing being true or false, and structure our models around that idea. Quantum physics puts us in a situation where that model is inadequate. That kind of a metaphysic does not apply in a world where something can be both wave and particle at the same time. An adequate description of the reality relies on probabilities, paradoxes, chaos theory, etc.

Facts are greater than theory, and the fact is that quantum level interactions are better understood with a nonbinary system of information. That has caused people to question whether binary systems, like noncontradiction, are adequate to describe macro level realities. It is not an outrageous idea, or it is only outrageous if you do not understand the scope of it.

And yet we see nothing that indicates the principle of non-contradiction is false. Only that the models need to be more nuanced, particularly on a quantum level. “Reality is more nuanced than I previously thought” isn’t the same as “the PNC must be false.”
