Nano-Printed Scaffolds Bring Direct Molecular Access to Quantum Photonics

Researchers 3D-nanoprinted hollow-core Photonic Scaffolds with up to 80% cladding openness, with models predicting attenuation at or below 1 dB/mm at that openness and experiments measuring sub-1 dB/mm losses at 68% openness. The waveguides supported dye diffusion in about 34 seconds, a 1.4 nL effective interaction volume, and quantum-dot emission with output photon statistics consistent with single-photon emission after transmission.

SLAC Scientist Develops Quantum Dots for Next-Generation Science

At SLAC National Accelerator Laboratory, Q-NEXT collaborator Shannon Harvey develops quantum dots — a mass-producible type of qubit. Driven by curiosity about nature and how things work, Harvey draws on her facility for working at the nanoscale.

Study Designs Nanoscale Defect Architectures to Strengthen Materials

"We didn't have modulators," Toni Taylor, a Los Alamos National Laboratory Fellow and physicist, says matter-of-factly, recalling work she began nearly two decades ago at the Center for Integrated Nanotechnologies (CINT) in Los Alamos. Modulators are the devices that allow scientists to control light-shaping its amplitude, phase, or frequency so it can carry information.

Graphene Quantum Dots Show Promise in Targeting Parkinson's-Related Protein Clumping

The buildup of a protein called a-synuclein (ASN) into toxic clumps is a hallmark of synucleinopathies, a group of neurodegenerative diseases that includes Parkinson’s and multiple system atrophy (MSA).

Quantum Nanomedicine: How Tiny Materials Could Tackle Big Medical Challenges

The Perspective highlights quantum dots, spin-polarized materials, topological states, and genetically encoded quantum biomaterials as early building blocks, while emphasizing that stability, biocompatibility, modeling, and in vivo quantum sensing remain major translational barriers.
