Configuration dependent crosstalk amplification in superconducting quantum processors

Year: 2026

Type: article

Abstract: We investigate the behaviour of cross-talk in superconducting quantum processors under repeated and structured gate operations. Using commercially available IBM quantum devices, we observe that sequences of two-qubit gates are associated with a measurable bias in the neighbouring spectator qubits without direct interaction, producing quantifiable changes in neighbouring spectator-qubit measurement outcomes that significantly exceed the corresponding control baselines.
