Cross Talk Vulnerabilities In Cloud Based Quantum Computers
summary
Experimental results on real IBM quantum machines show co-located circuits cause measurable interference: running dense two‑qubit CNOT flood patterns on neighboring or even nonadjacent qubits reduces a victim’s correct-output probability (examples drop a dominant result from near 100% to ~20%), and coordinated two‑sided activation or frequency‑matched pulses flips idle qubits. Tests use uploaded circuits with small compiler‑evasion delays, run on 5–127 qubit topologies, and note that multi‑tenancy is not yet natively supported so attacks are demonstrated with full testbed control.
