Spectral resolution of superconducting single photon detectors more than doubled

Scientist use superconducting detectors (MKIDs) to capture single photons coming from exoplanets. MKIDs constantly monitor their own kinetic inductance, which changes proportionally to the energy of an incoming photon. Researchers ...

How flawed diamonds 'lead' to flawless quantum networks

The color in a diamond comes from a defect, or "vacancy," where there is a missing carbon atom in the crystal lattice. Vacancies have long been of interest to electronics researchers because they can be used as 'quantum nodes' ...

First glimpse of hydrodynamic electron flow in 3D materials

Electrons flow through most materials more like a gas than a fluid, meaning they don't interact much with one another. It was long hypothesized that electrons could flow like a fluid, but only recent advances in materials ...

Nano-scale discovery could help to cool down overheating in electronics

A team of physicists at CU Boulder has solved the mystery behind a perplexing phenomenon in the nano realm: why some ultra-small heat sources cool down faster if you pack them closer together. The findings, published today ...
