This study experimentally validates sequential interaction-free measurement for up to five objects using Quandela's Ascella photonic processor, confirming theoretical predictions with error mitigation. By scaling a single-photon probe across multiple emulated absorbers, the work advances practical quantum interrogation techniques beyond traditional single-object limits.
Interaction-free measurement of multiple objects using a universal integrated photonic processor
arXiv:2604.04691v2 Announce Type: replace Abstract: The phenomenon of interaction-free measurement (IFM) enables the probabilistic detection of an absorbing object with reduced photon absorption. We report the experimental implementation of a generalized IFM of multiple objects using a single quantum probe on the cloud-based Ascella photonic processor developed by Quandela. We demonstrate sequential IFM of up to 5 emulated absorbers using a single photon, significantly extending the original IFM scheme for a single object. The experimental error-mitigated results confirm the theoretical predictions for this sequential IFM setup, and demonstrate a practical approach to scaling IFM to more complex quantum interrogation tasks.
