Approach Uses Bayesian Analysis to Speed Spectroscopy Results
PHOENIX, Aug. 19, 2019 — Scientists from Arizona State University are leveraging the tools of data science to study molecular activity more quickly than is possible through traditional fluorescence correlation spectroscopy (FCS). While FCS provides estimates of dynamical...
Naturally Occurring Vibrations in Artificial Atoms Could Be Used to Build Quantum Sensors
BRISTOL, England, Aug. 19, 2019 — The discrete nature of photons that are emitted from individual atoms ensures low fluctuations in brightness, as only one photon is emitted at a time. Scientists believe this property could be useful in developing future quantum technologies where...
Lensless Endoscope Produces 3D Images of Ultrasmall Objects
DRESDEN, Germany, Aug. 16, 2019 — Researchers at Dresden University of Technology (TU Dresden) have developed a tiny, self-calibrating endoscope that produces 3D images of objects smaller than a single cell. Without a lens or any optical, electrical, or mechanical components, the...
Shining Light Through Bleach Creates Fluorescent Quantum Defects
CAMBRIDGE, Mass., Aug. 15, 2019 — Using household bleach and light, MIT researchers have created carbon-nanotube-based single-photon emitters, also known as fluorescent quantum defects. The defects can be synthesized quickly and at large scale using this method, the researchers...
At SPIE Optics + Photonics, Going Back to Get Ahead
SAN DIEGO, Aug. 15, 2019 — For photonics, forward progress may start by going in reverse — when it makes sense. That was a theme in the SPIE Optics + Photonics conference held in San Diego Aug. 11-15. An example showed up in a plenary talk given by Jelena Vuckovic, a...
