A quiet but intense competition in quantum computing has produced remarkable advances, as research teams in China and the United States push the boundaries of trapped-ion quantum systems and quantum chips. Record-Breaking Ion-Based Systems Atom Computing has constructed the world’s largest trapped-ion quantum computer, featuring 1,125 qubits as announced in October 2023. The system marks … Continue reading China’s 504-Qubit Xiaohong Chip and 512-Ion Traps Challenge U.S. 1,125-Qubit Quantum Systems
