- 1Programmable fusion method scales up photonic quantum states●Deterministic and programmable fusion for the scalable generation of photonic graph states
Researchers report a deterministic and programmable fusion technique for generating photonic graph states at scale, published in Nature. Graph states are entangled networks of photons that underpin photonic quantum computing and quantum networking. The advance suggests fusion operations can be controlled on demand rather than relying on probabilistic outcomes, a key hurdle to building large optical quantum systems.
