Quantum Computing Achieves New Milestone with Record of 51 Qubits for Generating Genuine Entanglement 

Chinese scientists have set a new world record for generating genuine entanglement, with 51 superconducting qubits prepared and verified in a recent study published in Nature. The breakthrough marks a significant step forward in the scalability and controllability of quantum systems and has important implications for studying multi-body quantum entanglement, implementing large-scale quantum algorithms, and measurement-based quantum computing.

Entanglement is a fundamental property of quantum mechanics and a core resource for quantum information processing. For years, scientists around the world have been striving to achieve large-scale, multi-qubit entanglement. Since the first preparation of a three-qubit GHZ state using nuclear magnetic resonance in 1998, the preparation of genuine multi-body entangled states has become an important means of characterizing the scalability of various …
