French photonic quantum computing company Quandela is looking to partner with Korean firms to manufacture its photonic quantum chips. The move would tie Quandela's quantum photonics technology to South Korea's semiconductor manufacturing base, potentially speeding up production of its quantum processors. Details on specific partners, timelines, or investment amounts were not disclosed, leaving the scope of the collaboration uncertain.
- 5Programmable fusion advances scalable photonic graph statesโผDeterministic and programmable fusion for the scalable generation of photonic graph states
Researchers publishing in Nature report a deterministic and programmable fusion technique for generating photonic graph states at scale. Photonic graph states are entangled light states central to photonic quantum computing, networking and repeaters. Making fusion deterministic rather than probabilistic, while keeping it programmable, is presented as a step toward scalable quantum photonics. The finding matters because scaling entangled photon sources has been a key bottleneck for optical quantum technologies.
