The future Quantum Internet will provide radically new internet applications by enabling quantum communication between any two points on Earth.

The Quan­tum Inter­net Alliance (QIA) tar­gets a Blue­print for a pan-Euro­pean Quan­tum Inter­net by ground-break­ing tech­no­log­i­cal advances, cul­mi­nat­ing in the first exper­i­men­tal demon­stra­tion of a ful­ly inte­grat­ed stack run­ning on a mul­ti-node quan­tum net­work.

QIA will push the fron­tier of tech­nol­o­gy in both end nodes (trapped ion qubits, dia­mond NV qubits, neu­tral atom qubits) and quan­tum repeaters (rare-earth-based mem­o­ries, atom­ic gas­es, quan­tum dots) and demon­strate the first inte­gra­tion of both sub­sys­tems. We will achieve entan­gle­ment and tele­por­ta­tion across three and four remote quan­tum net­work nodes, there­by mak­ing the leap from sim­ple point-to-point con­nec­tions to first mul­ti-node net­works. We will demon­strate the key enabling capa­bil­i­ties for mem­o­ry-based quan­tum repeaters, result­ing in proof-of-prin­ci­ple demon­stra­tions of ele­men­tary long-dis­tance repeater links in the real-world, includ­ing the longest such link world­wide.

Hand in hand with hard­ware devel­op­ment, we will real­ize a soft­ware stack that will pro­vide fast, reac­tive con­trol and allow arbi­trary high-lev­el appli­ca­tions to be real­ized in plat­form-inde­pen­dent soft­ware. QIA’s indus­try part­ners exam­ine real world use cas­es of appli­ca­tion pro­to­cols and their hard­ware require­ments. We val­i­date the full stack on a small Quan­tum Inter­net by per­form­ing an ele­men­tary secure quan­tum cloud com­pu­ta­tion. We val­i­date the design of the Blue­print archi­tec­ture by a large-scale sim­u­la­tion of a pan-Euro­pean Quan­tum Inter­net. Through syn­er­gy of lead­ing indus­tri­al, aca­d­e­m­ic and RTO part­ners, QIA’s Blue­print will set the stage for a strong Euro­pean Quan­tum Inter­net indus­try.

The main objec­tive of the Flag­ship is to con­sol­i­date and expand Euro­pean sci­en­tif­ic lead­er­ship and excel­lence in this research area as well as to trans­fer quan­tum physics research from the lab to the mar­ket by means of com­mer­cial appli­ca­tions and dis­rup­tive tech­nolo­gies. With over 5000 researchers from acad­e­mia and indus­try involved in this ini­tia­tive through­out its life­time, it aims to cre­ate the next gen­er­a­tion of dis­rup­tive tech­nolo­gies that will impact Europe’s soci­ety, plac­ing the region as a world­wide knowl­edge- based indus­try and tech­no­log­i­cal leader in this field.
