5+ day, 1+ hour ago   (378+ words) New work suggests that building nontrivial topologies around optical vortices could be a better strategy than engineering delicate polarisation patterns across an entire beam Structured light is light with a designed spatial pattern. It can be shaped into standard topological…...

6+ day, 3+ hour ago   (422+ words) The double-slit experiment is perhaps the most iconic demonstration in quantum mechanics: showing how a single particle’s wavefunction interferes with itself as it passes through two slits at once, with a tangible impact on where the particle is ultimately observed....

3+ week, 5+ day ago   (392+ words) New research shows that sensors based on exceptional points can beat ordinary sensors in ideal quantum-limited measurements, but only if the light input, loss rate, and the perturbation being measured are carefully matched Exceptional points occur in open physical systems…...
