Nonlocal wavefront shaping through complex media
Yanis Trouyet, Neelan Gounden, Pedro Ornelas +3
Wavefront shaping is a key technique for mitigating scattering in complex media, enabling advanced imaging and optical communication. Yet existing approaches are inherently local,…
Evidence for Counterfactual Violation of Local Conservation Laws in Quantum Events
Patrick Cameron, Francesco Di Colandrea, Filippo Cardano +1
Physical conservation laws, such as those of energy and momentum, are generally believed to hold exactly and locally in spacetime, including in quantum phenomena. Yet Aharonov, Pop…
Tunable Quantum Interference in Free Space with a Liquid-Crystal Metagrating
Maria Gorizia Ammendola, Italo Machuca Flores, Sneha Dey +9
Structured optical materials provide a promising platform for photonic quantum information processing in free space. Beam splitters, a fundamental building block of photonic circui…
Towards robust detection of entangled two-photon absorption
Raj Pandya, Patrick Cameron, Chloé Vernière +5
Over the last 50 years entangled photon pairs have received attention for use in lowering the flux in two-photon absorption imaging and spectroscopy. Despite this, evidence for ent…
