The future Quan­tum Inter­net will pro­vide rad­i­cal­ly new inter­net appli­ca­tions by enabling quan­tum com­mu­ni­ca­tion between any two points on Earth. In the com­ing years, the Quan­tum Inter­net Alliance (QIA) first tar­gets a Blue­print for a pan-Euro­pean Quan­tum Inter­net by ground-break­ing tech­no­log­i­cal advances, cul­mi­nat­ing in the first exper­i­men­tal demon­stra­tion of a ful­ly inte­grat­ed net­work 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 the 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 will val­i­date the full stack on a small Quan­tum Inter­net by per­form­ing an ele­men­tary secure del­e­gat­ed quan­tum com­pu­ta­tion in the cloud. We will val­i­date the design of the Blue­print archi­tec­ture by a large-scale sim­u­la­tion of a pan-Euro­pean Quan­tum Inter­net using real world fibre data.

You can now join us in this ambi­tious endeav­our! We are look­ing for excel­lent appli­ca­tions with dif­fer­ent back­grounds (the­o­ry and exper­i­men­tal physics, com­put­er sci­ence, elec­tri­cal engi­neer­ing) who like to work in a team effort towards our long term goal of real­iz­ing large-scale quan­tum net­works.
