A lithium niobate converter shifts 393 nm photons from trapped calcium ions to 1550 nm telecom light with 28.8% efficiency and very little noise, a step toward larger quantum networks.
A photon emitted by a qubit is loud at first and fades like a struck bell, which is exactly the wrong shape for the next qubit to absorb. Engineering the waveguide's dispersion reverses the pulse and pushes the absorption probability to 100% in theory.
Breakthrough quantum encryption system maintained continuous operation for six hours while achieving highest secure key rates yet for this technology.
