Coherence as a resource for -box and quantum pigeonhole paradoxes
Som Kanjilal, Rafael Wagner, Ernesto F. Galvão
Pre- and post-selection (PPS) paradoxes are striking demonstrations of quantum nonclassicality. Logical PPS paradoxes, where inferences made with the Aharonov-Bergmann-Lebowitz (AB…
Commutativity from a single Bargmann invariant equality
Rafael Wagner, Ernesto F. Galvão
Noncommutativity of states and observables is a fundamental signature of quantum theory, and a minimal requirement for nonclassicality. We provide a universal necessary and suffici…
Interaction-free measurement of multiple objects using a universal integrated photonic processor
Sara Franco, Anita Camillini, Ernesto F. Galvão
The phenomenon of interaction-free measurement (IFM) enables the probabilistic detection of an absorbing object with reduced photon absorption. We report the experimental implement…
Native linear-optical protocol for efficient multivariate trace estimation
Leonardo Novo, Marco Robbio, Ernesto F. Galvão +1
The Hong-Ou-Mandel test estimates the overlap between spectral functions characterizing the internal degrees of freedom of two single photons. It can be viewed as a photon-native p…
Optimal distillation of photonic indistinguishability
Francesco Hoch, Anita Camillini, Giovanni Rodari +13
Imperfect photons' indistinguishability limits the performance of photonic quantum communication and computation . Distillation protocols, inspired by entanglement purification, en…
Measuring unitary invariants with the quantum switch
Pedro C. Azado, Rafael Wagner, Rui S. Barbosa +1
Bargmann invariants, multivariate traces of states, completely characterize any unitary-invariant property of a set of states. Unitary invariants enable the description of quantum…
