SQuaD Part­ner KEE­Quant Unveils Com­mer­cial-Gra­de Chip-Sca­le QKD

KEE­Quant GmbH publishes Press Release on inte­gra­ted QKD Pho­to­nic Chips enab­ling sca­lable, cost-effi­ci­ent quan­tum-secu­re Com­mu­ni­ca­ti­ons for Real-World Net­works:

Fürth, Ger­ma­ny – 2026-03-16 – KEE­Quant today announ­ced the launch of its com­mer­cial-gra­de chip-sca­le QKD tech­no­lo­gy, mar­king a major advan­ce in quan­tum-secu­re com­mu­ni­ca­ti­ons. This breakth­rough rede­fi­nes the eco­no­mics and prac­ti­cal­i­ty of quan­tum key dis­tri­bu­ti­on by repla­cing bul­ky, com­plex opti­cal assem­blies with pho­to­nic inte­gra­ti­on and tur­ning quan­tum-safe key exch­an­ge into a rea­li­stic net­work upgrade for tele­com ope­ra­tors, data cen­ter pro­vi­ders and cri­ti­cal infra­struc­tu­re orga­niza­ti­ons. The result is smal­ler, more sca­lable and more cost-effi­ci­ent sys­tems that pre­ser­ve com­pa­ti­bi­li­ty with exis­ting fiber envi­ron­ments and estab­lished encryp­ti­on solu­ti­ons, making broa­der adop­ti­on far more prac­ti­cal for orga­niza­ti­ons pre­pa­ring their infra­struc­tu­re for the long-term cryp­to­gra­phic risks posed by quan­tum com­pu­ting.

Pho­to­nic inte­gra­ti­on at the core of KEEQuant’s next-gene­ra­ti­on chip-sca­le QKD sys­tems

“For years, QKD has been seen as stra­te­gi­cal­ly important, but too com­plex and too cos­t­ly for broad deploy­ment,” said Imran Khan, Mana­ging Direc­tor at KEE­Quant. “Brin­ging QKD to the chip sca­le chan­ges that. It gives quan­tum-safe key exch­an­ge the eco­no­mics and prac­ti­cal­i­ty it needs to move into real-world net­works.” Based on this tech­no­lo­gy, KEE­Quant will begin ship­ments to first cus­to­mers later this year.

Why chip-sca­le QKD is a mar­ket inflec­tion point:

  • A dra­ma­ti­cal­ly lower sys­tem-cost basis fun­da­men­tal­ly chan­ges the eco­no­mics of QKD
  • Wider acces­si­bi­li­ty makes quan­tum-safe key exch­an­ge via­ble for many more appli­ca­ti­ons and cus­to­mers
  • Broa­der mar­ket adop­ti­on beco­mes pos­si­ble as QKD moves bey­ond pre­mi­um niche deploy­ments
  • New busi­ness models and inte­gra­ti­on oppor­tu­ni­ties open up across com­mu­ni­ca­ti­ons, secu­ri­ty and quan­tum-net­work infra­struc­tu­re

KEEQuant’s cur­rent gene­ra­ti­on QKD sys­tems will be used as a plat­form for chip-based QKD

Tech­ni­cal­ly, the mile­stone is the inte­gra­ti­on and sys­tem-level vali­da­ti­on of the major opti­cal buil­ding blocks requi­red for QKD on pho­to­nic chips. Using com­mer­cial PICs, KEE­Quant brought trans­mit­ter and recei­ver lasers, modu­la­ti­on, recei­ver optics and detec­tion to the chip sca­le, repla­cing bul­ky opti­cal assem­blies with a com­pact pho­to­nic archi­tec­tu­re. Bey­ond minia­tu­riza­ti­on alo­ne, this estab­lishes the engi­nee­ring basis for repeata­ble pack­a­ging, manu­fac­tura­ble sys­tem design and relia­ble sys­tem-level inte­gra­ti­on of chip-sca­le QKD buil­ding blocks.

With this launch, KEE­Quant moves quan­tum-safe com­mu­ni­ca­ti­ons from rese­arch and pilot deploy­ments into com­mer­ci­al­ly via­ble infra­struc­tu­re.

KEE­Quant GmbH is a start-up com­pa­ny spe­cia­li­zing in quan­tum-secu­re com­mu­ni­ca­ti­ons. Its core busi­ness is the deve­lo­p­ment and sale of Quan­tum Key Dis­tri­bu­ti­on (QKD) sys­tems, Key Manage­ment Sys­tems (KMS), and hybrid appli­ca­ti­ons of post-quan­tum cryp­to­gra­phy (PQC). The minia­tu­riza­ti­on of QKD tech­no­lo­gy onto pho­to­nic chips, tog­e­ther with cer­ti­fi­ca­ti­on and appr­oval of the over­all sys­tem, forms the foun­da­ti­on for long-term secu­re com­mu­ni­ca­ti­ons. This helps ensu­re that users’ secu­ri­ty-cri­ti­cal data flows remain pro­tec­ted against unaut­ho­ri­zed access even in future thre­at sce­na­ri­os, such as attacks using powerful quan­tum com­pu­ters.

Fun­ding
This work has recei­ved fun­ding through the SEQRET pro­ject under the Euro­pean Union’s Digi­tal Euro­pe Pro­gram­me, within the frame­work of Euro­QCI, under call DIGITAL-2021-QCI-01-INDUSTRIAL (Pro­ject ID: 101091591). SEQRET advan­ces secu­re and indus­tria­li­zed QKD sys­tems for Euro­pean tele­com­mu­ni­ca­ti­on net­works, inclu­ding pho­to­nic inte­gra­ti­on, manu­fac­tu­ra­bi­li­ty, and cer­ti­fi­ca­ti­on rea­di­ness.
