Generation of Photonic Graph States with minimal number of quantum emitters
Researchers have proposed a method for generating photonic graph states that minimises the number of quantum emitters required. The work addresses the challenge of deterministic preparation of these states, which are used in measurement- and fusion-based quantum computing, quantum networks, and sensing. It also engages with recent efforts to find efficient preparation schemes, including heuristic optimisation approaches.

This could allow photonic quantum computing groups to build small graph-state sources with fewer quantum emitters, reducing the hardware overhead for near-term fusion-based prototypes.
The scheme targets a key practical constraint—emitter count—and if it is compatible with existing quantum dot or color center emitters, experimental groups could test it within two years, accelerating development of compact photonic quantum processors.
