Bell violation with path-entangled number states under realistic detection
Christoph F. Wildfeuer
A single photon delocalised over two modes is entangled, and whether that entanglement can violate a Bell inequality has been disputed for three decades. In principle it is settled…

Counterfactual Quantum Sensing: What Interaction-Free Measurement Can and Cannot Buy
Christoph F. Wildfeuer
The paper analyzes interaction‑free (counterfactual) quantum sensing as a channel‑estimation problem, showing that such interferometric schemes provide no advantage for estimating…
