Chinese Scientists Break Quantum Computing Record
Chinese physicists have achieved quantum entanglement with 18 qubits, surpassing the previous world record of 10. The achievement represents a step toward realizing large-scale quantum computing, according to "18-Qubit Entanglement with Six Photons' Three Degrees of Freedom," published in the journal Physical Review Letters.
Physicist Pan Jianwei, along with his colleagues from the University of Science and Technology of China, achieved the new record by simultaneously exploiting three different degrees of freedom—paths, polarization, and orbital angular momentum—of six photons, the fundamental particle of light.
The outcome combination resulted in a stable 18-qubit state. Full control over the number of entangled particles determines the fundamental ability for quantum information processing, according to the study.
