Telecom band quantum dot technologies for long-distance quantum networks – ArXiv

Semiconductor quantum dots (QDs) so far have exhibited exceptional performance as key elements, i.e., quantum light sources and spin-photon interfaces, for quantum repeaters, but only in the near-infrared (NIR) regime. This review presents the physics and the technological developments towards epitaxial QD devices emitting at the telecom O- and C-bands for quantum networks. The paper also discusses the challenges and opportunities to realise future telecom QD devices with improved performance and expanded functionalities by taking advantage of hybrid integration.

Guest Post: 6G – Fitting the Market Needs of the 2030s

"In 6G standardisation it might be a good idea to listen to the needs of the non-public network clientele as this is the only sizable area of growth for the 3GPP ecosystem right now." In this guest post Heikki Almay, CEO of Poutanet, sets out some ideas for 6G architecture that might help make 6G a more marketable proposition.
