Sha­ping the Future of Quan­tum Com­mu­ni­ca­ti­on

SQuaD

Inno­va­tions for Quan­tum Com­mu­ni­ca­ti­on in Ger­ma­ny

Quan­tum Com­mu­ni­ca­ti­on is a key tech­no­lo­gy for ensu­ring the secu­ri­ty of digi­tal infra­struc­tures in our socie­ty. By exploi­ting Quan­tum Effects, it pro­mi­ses tap-pro­of data trans­mis­si­on within com­mu­ni­ca­ti­on and infor­ma­ti­on net­works. One of today’s most wide­ly rese­ar­ched appli­ca­ti­ons is that of quan­tum-based Key Dis­tri­bu­ti­on (QKD). In addi­ti­on to Post-Quan­tum Cryp­to­gra­phy (PQC), this tech­no­lo­gy can signi­fi­cant­ly enhan­ce both IT secu­ri­ty and Ger­many’s tech­no­lo­gi­cal sove­reig­n­ty in a hyper­con­nec­ted world.

Pro­ject Part­ners in SQuaD

The cen­tral goal of the umbrel­la pro­ject is to ensu­re a sus­tainable trans­fer of tech­no­lo­gy from the sci­en­ti­fic com­mu­ni­ty to indus­try and to lay the foun­da­ti­ons for the estab­lish­ment of a Ger­man Quan­tum Com­mu­ni­ca­ti­on Indus­try. For this, SQuaD will bund­le acti­vi­ties in the field of Quan­tum Com­mu­ni­ca­ti­on throug­hout Ger­ma­ny and pro­mo­te the dia­log with other rese­arch hubs and start-up incu­ba­tors in the field of clas­si­cal com­mu­ni­ca­ti­on tech­no­lo­gy and IT secu­ri­ty.

The Pro­ject Part­ners in SQuaD are:

Inno­va­ti­on Hub

The Inno­va­ti­on Hub for Quan­tum Com­mu­ni­ca­ti­on is inten­ded to sys­te­ma­ti­cal­ly link and thus fur­ther inten­si­fy Ger­many’s exis­ting and com­pre­hen­si­ve rese­arch per­for­mance in the field of Quan­tum Com­mu­ni­ca­ti­on with the indus­tri­al deve­lo­p­ment of com­pon­ents, sys­tems and solu­ti­ons for Quan­tum Com­mu­ni­ca­ti­on. The Inno­va­ti­on Hub con­nects the acti­ve stake­hol­ders, pro­jects and cur­rent topics in Quan­tum Com­mu­ni­ca­ti­on, rather than con­nec­ting indi­vi­du­al, unre­la­ted topics.

The Inno­va­ti­on Hub con­sists of the umbrel­la pro­ject SQuaD for ser­vices coor­di­na­ting and sup­port­ing the exten­si­on of an inde­pen­dent Quan­tum Com­mu­ni­ca­ti­on Eco­sys­tem in Ger­ma­ny and the fol­lo­wing six indus­try-led pro­jects:

Test­beds for Quan­tum Com­mu­ni­ca­ti­on in Ger­ma­ny

SQuaD is the cen­tral point of cont­act for the exper­ti­se and infra­struc­tu­re of Quan­tum Com­mu­ni­ca­ti­on in Ger­ma­ny. The scope of SQuaD tasks includes the pro­vi­si­on of test­beds and the crea­ti­on of an over­view of the num­e­rous exis­ting user plat­forms or test­beds in Ger­ma­ny that are available and usable for rese­arch and deve­lo­p­ment in the field of Quan­tum Com­mu­ni­ca­ti­on.

The test­beds include exis­ting fiber optic net­works (so-cal­led dark fibers), free-beam links, base sta­ti­ons for satel­li­te trans­mis­si­on, but also test­beds to cha­rac­te­ri­ze sin­gle-pho­ton sources and detec­tors.

The test­bed map shows whe­re test labs for Quan­tum Com­mu­ni­ca­ti­on Expe­ri­ments are curr­ent­ly loca­ted in Ger­ma­ny and for which topics they are sui­ta­ble.

If your exis­ting or requi­red test­bed is not included on the map, plea­se cont­act us at squad@ptb.de.
