This breakthrough demonstrates that measurement-based optical quantum computing can overcome the scalability hurdles associated with multi-photon sources by leveraging high-dimensional encoding. By achieving genuine 16-qubit entanglement on a single chip, this work validates a cleaner pathway toward fault-tolerant, general-purpose quantum processors without relying solely on complex gate operations.
Chinese Chip built a 16-qubit state on a single chip

Hefei’s Guizhen Chip Technology & USTC achieved a 16-qubit GHZ state on a single chip, a record for on-chip multi-qubit entanglement.
Guizhen Chip Technology and the Ren Xifeng group of China have generated a 16-qubit GHZ state on a single chip, establishing the largest on-chip multi-qubit entangled state reported to date. The team verified that ten of these sixteen qubits…
