How this entity was disambiguated
This entity first appeared as the object of triple T3081299 — resolving that mention is where its identity was fixed. The disambiguator weighed these candidate entities and picked the highlighted one (or “None”, minting a new entity). This is how homonymy is resolved: the same surface form can point to different entities.
Target entity: Aspect experiment on Bell inequality tests (1982) Context triple: [Alain Aspect, notableExperiment, Aspect experiment on Bell inequality tests (1982)]
-
A.
Einstein–Podolsky–Rosen paradox
The Einstein–Podolsky–Rosen paradox is a thought experiment that challenges the completeness of quantum mechanics by highlighting the strange, nonlocal correlations predicted for entangled particles.
-
B.
Hanbury Brown and Twiss effect
The Hanbury Brown and Twiss effect is a quantum optical phenomenon in which correlations in the arrival times of identical particles, such as photons, reveal their underlying statistical and coherence properties.
-
C.
Ives–Stilwell experiment
The Ives–Stilwell experiment is a classic test of special relativity that measured the relativistic Doppler effect to confirm time dilation for fast-moving ions.
-
D.
delayed-choice experiment
The delayed-choice experiment is a quantum mechanics thought experiment and class of real experiments showing that a particle’s behavior as a wave or particle can appear to be decided by measurements made after it has entered, or even passed through, an experimental apparatus.
-
E.
Wigner’s friend thought experiment
Wigner’s friend thought experiment is a foundational quantum mechanics scenario that explores the role of observers and consciousness in measurement by considering how different observers can assign conflicting quantum states to the same system.
- F. None of above. chosen
- G. Unsure - the case is ambiguous/there is not enough information to decide.

How these facts were elicited
The pipeline generated the facts above by prompting gpt-5.1 with this entity's name + description and the instruction below.
You are a knowledge base construction expert. Given a subject entity and a description of it, return factual statements that you know for the subject as a JSON list of dictionaries(triples), where keys must be "subject", "predicate" and "object". The number of facts may be very high, between 25 to 50 or more, for very popular subjects. For less popular subjects, the number of facts can be very low, like 5 or 10. # Requirements - If you don't know the subject at all, return an empty list. - If the subject is not a named entity, return an empty list. - Include at least one triple where predicate is "instanceOf". - Do not get too wordy. - Separate several objects into multiple triples with one object.
