Szabó Gábor 2025. november 25-én "Noncommuting Common Causes Revisited" címmel tart előadást a bécsi Institute for Quantum Optics and Quantum Information intézetben.

 Az előadásra a Physics meets Philosophy in Vienna szemináriumi sorozat keretében kerül sor.

Absztrakt:

In this talk, I will revisit the concept of noncommuting common causes; refute two objections raised against them, the triviality objection and the lack of causal explanatory force; and explore how their existence modifies the EPR argument. More specifically, we show that 1) product states screening off all quantum correlations do not compromise noncommuting common causal explanations; 2) noncommuting common causes can satisfy the law of total probability; 3) perfect correlations can have indeterministic noncommuting common causes; and, as a combination of the above claims, 4) perfect correlations can have noncommuting common causes which are both nontrivial and satisfy the law of total probability.
