Physicists make leaps in reading out qubits with laser light
Qubits are a basic building block for quantum computers, but they're also notoriously fragile—tricky to observe without erasing their information in the process. Now, new research from the University of Colorado Boulder ...

Putting the theory of special relativity into practice, by counting galaxies
Scientists who study the cosmos have a favorite philosophy known as the "mediocrity principle," which, in essence, suggests that there's really nothing special about Earth, the sun or the Milky Way galaxy compared to the ...

Highly efficient acousto-optic modulation using non-suspended thin-film lithium niobate-chalcogenide hybrid waveguides
Traditional acousto-optic (AO) devices based on bulk crystal materials have weak energy confinement abilities for both photons and phonons, leading to a low AO interaction strength. Compared with bulk materials, photonic ...
