QR.X / QR.N

In the rese­arch asso­cia­ti­on Quan­tum Repeater.Link – in short QR.X – more than 40 part­ners from aca­de­mic rese­arch insti­tu­tes, insti­tu­tes, and com­pa­nies have col­la­bo­ra­ted to deve­lop a key com­po­nent of future Quan­tum Com­mu­ni­ca­ti­on Net­works: the Quan­tum Repea­ter. The pro­ject ran from August 2021 to Decem­ber 2024 and was fun­ded by the Bun­des­mi­nis­te­ri­um für Bil­dung und For­schung (BMBF).

In Janu­ary 2025, the new­ly estab­lished rese­arch pro­ject “Quantumrepeater.Net (QR.N)” was laun­ched, buil­ding on the fin­dings of the pre­vious work in QR.X. In this joint pro­ject, which is also fun­ded by the BMBF, 42 part­ners from rese­arch and indus­try are working tog­e­ther to achie­ve cru­cial pro­gress in the deve­lo­p­ment and imple­men­ta­ti­on of Quan­tum Net­works and to demons­tra­te the basic func­tion­a­li­ties of Quan­tum Repea­ters on test­beds out­side of labo­ra­to­ry envi­ron­ments.
