Quantum Dots Emit Entangled Photons at 50% Transmission
A rack-integrated source utilizes semiconductor quantum dots to emit entangled photons in the telecom C-band, achieving over 50% transmission.
Air-stable, ultrathin superconductors developed for more scalable quantum devices
Super-thin superconducting materials, which are only one or a few atoms thick, have unique properties scientists can leverage to produce more compact, scalable, and efficient quantum devices. But these fragile materials degrade so rapidly in air that they are difficult to study or manufacture.
$1/2$ is the Limit, Quantum States’ Product Overlap Now Fully Mapped
New research fully maps the product test’s acceptance probability, $\mathrm{PT}_n(\omega)$, revealing a precise curve for determining when multipartite quantum states are fully unentangled.
