The proposed idea is concerned with the investigation of the probability of subatomic quantum communication between chemical substances by use of “interferometric quantum eraser” pattern analysis, which would be the first step toward the further comprehensive study of similar natural communications between the medications and diseased organic tissues. The hypothesis is based on the idea that subatomic particles, such as photons, attempt to access or gain complementary information causing their “wave–particle duality” shifting, which is used to observe their time-sequenced activities. Such information would probably be provided by subatomic quantum communication action demonstrated between the substances in a chemical reaction. Similarly, the medications may have curing effects on a diseased organic tissue after such “natural” communication by which complementary information is transferred from the subatomic properties of a chemical substance to the diseased organic tissue at the same level for the treatment.
