**Example Attack Scenarios:**

Scenario #1: A financial firm runs a proprietary optimisation circuit on a shared QPU. A malicious co-tenant schedules a circuit adjacent on the QPU topology and uses quantum crosstalk to degrade the victim's fidelity (Li et al., NDSS 2025; Ash-Saki et al., ISLPED 2020), corrupting results the firm relies on - without ever needing co-execution.

Scenario #2: A tenant's circuit is scheduled on physical qubits immediately after a competitor's workload. Because standard reset gates do not fully clear state (Xu et al., CCS 2023), the tenant observes residual state leaking information about the previous, confidential computation.

No formal standard yet covers QPU tenant isolation. NIST and NCSC have not published guidance on quantum platform security. The relevant published research includes Li et al. on crosstalk-induced side-channel threats (NDSS 2025), Ash-Saki et al. on crosstalk-based fault injection (ISLPED 2020), and Xu et al. on reset-operation state leakage (CCS 2023). Where DORA Article 28 third-party risk applies to financial entities using quantum platform services, the supervisory expectation is that platform security claims are evidenced rather than assumed.
