How this entity was disambiguated
This entity first appeared as the object of triple T11265287 — 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: cavity quantum electrodynamics Context triple: [Purcell effect, field, cavity quantum electrodynamics]
-
A.
Jaynes–Cummings model
The Jaynes–Cummings model is a fundamental quantum optics model describing the interaction between a two-level atom and a single mode of the quantized electromagnetic field, widely used to study light–matter coupling and cavity quantum electrodynamics.
-
B.
quantum electrodynamics
Quantum electrodynamics is the quantum field theory that describes how light and matter interact through the exchange of photons, forming the foundation of our understanding of electromagnetic forces at the subatomic level.
-
C.
Rabi oscillation
Rabi oscillation is a quantum mechanical phenomenon in which a two-level system, such as an atom or qubit, undergoes coherent periodic transitions between its states when driven by a resonant oscillatory field.
-
D.
Dicke superradiance
Dicke superradiance is a quantum optical phenomenon in which a group of closely spaced excited atoms emit light cooperatively, producing an intense, short burst of radiation much stronger than the sum of their independent emissions.
-
E.
quantum cascade laser
A quantum cascade laser is a semiconductor laser that emits in the mid- to far-infrared range using engineered quantum wells to produce photons through intersubband electronic transitions.
- F. None of above. chosen
- G. Unsure - the case is ambiguous/there is not enough information to decide.

Instruction
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.
Input
