    "body_text": "The authors applied crosstalk-inducing activity on six IBM superconducting processors and one IQM processor. Every platform showed an attack effect, although devices with the same coupling graph had different vulnerability profiles. The largest reported victim-qubit outcome-flip probability reached 60 percent, and quantum random-access-code success declined under interference. These are controlled experiments on the tested hardware, not evidence of a remote production exploit, but they show that topology alone does not predict crosstalk exposure.",
