Anne Broadbent, the PI of the University of Ottawa and Canadian project coordinator, is now giving our third workshop tutorial, on quantum cryptography: communication, delegated computation, voting, signatures, among other tasks. Thank you Anne!

Here's Quantum and Linear-Optical Computation group @INL's Lorenzo Catani (in good company) at the FoQaCiA workshop presenting his joint work with Laurens Walleghem, on thought experiment designed to clarify assumptions about the quantum-mechanical measurement process. foqacia.org/foqacia-worksh…

Proudly organized by the Quantum and Linear-Optical Computation group @INL team, with brilliant support by our INL colleagues Filipa Bernardo et al.

New Quantum and Linear-Optical Computation group @INL paper out in PRA about validation techniques for Gaussian boson sampling based on detector binning! This is joint work of Leonardo Novo and Benoît Seron with colleagues from Imperial College and Brussels. Congrats! INL Phoqusing EU project journals.aps.org/pra/abstract/1…

New Quantum and Linear-Optical Computation group @INL preprint! Laurens Walleghem (INL, Univ. York) discusses how black-hole physics and the measurement problem play out in Wigner's friend scenarios. Congrats Laurens! arxiv.org/abs/2507.05369

New Quantum and Linear-Optical Computation group @INL paper published in Linear Algebra and Applications! It describes how the quantum theory of photonic indistinguishability is linked to counter-examples to mathematical conjectures on permanents. Congrats Leonardo, Benoît and colleagues! sciencedirect.com/science/articl…

New Quantum and Linear-Optical Computation group @INL preprint! Alexandra Ramôa, Gilberto Cunha, André Sequeira, Michael de Oliveira and Luís Soares Barbosa propose a Bayesian quantum-enhanced reinforcement learning algorithm, showing the potential for quantum advantage. Congrats! INL arxiv.org/abs/2507.18606

New Quantum and Linear-Optical Computation group @INL group preprint! Rafael Wagner, together with Li (South China U.) and Zhang (Hangzhou Dianzi U.) investigate the characterization of quantum imaginarity using Bargmann invariants. Congrats Rafael!arxiv.org/abs/2507.14878

New Quantum and Linear-Optical Computation group @INL paper out! We use a tunable interferometer to do variationally learn near-optimal quantum cloning machines. Collaboration with Fabio Sciarrino's group, FAST Group, Mina Doosti, Sebastià Nicolau. opg.optica.org/opticaq/fullte…

New Quantum and Linear-Optical Computation group @INL preprint! We show processes featuring indefinite causal order (switches) can be used to measure and use unitary invariants for applications. Congrats Pedro Azado, Rafael Wagner, Rui Soares Barbosa and Ernesto Galvão! FoQaCiA INL scirate.com/arxiv/2508.023…

New Quantum and Linear-Optical Computation group @INL paper published! This is a study on the role of contextuality in a Wigner's friend scenario, designed to study the measurement problem in quantum mechanics. Joint work of Laurens Walleghem, Rafael Wagner, and colleagues from Canada. Congrats! quantum-journal.org/papers/q-2025-…

New preprint by Alexandra Ramôa, Luís Paulo Santos, and Akihito Soeda. They propose a novel Hamiltonian learning algorithm with reliable performance against other low cost methods, especially in the presence of decoherence. Congrats! EPIQUE arxiv.org/abs/2508.07120

Quantum and Linear-Optical Computation group @INL members presented their research this week at the IX Paraty Quantum Information Workshop in Brazil. Sara Franco (pictured), Wagner Balthazar, Pedro Azado, and Ernesto Galvão presented talks and posters. Sea, sun, and quantum! 2025.paratyquantum.org/2025/

New Quantum and Linear-Optical Computation group @INL paper out! Rafael Wagner and collaborators show that a Wigner's friend argument can be made having contextuality rather than nonlocality at its core, extending our understanding of the measurement problem. Congrats Rafael! journals.aps.org/pra/abstract/1…
