China unveiled on Thursday the country's first dual-core neutral atomic quantum computer, the "Hanyuan-2," marking a new stage for the country's neutral atomic quantum computing technology, transitioning from the earlier single-core era to dual-core collaboration.
The research and development effort is led by the Chinese Academy of Sciences, in collaboration with Wuhan University, Huazhong University of Science and Technology, and the Wuhan Institute of Quantum Technology.
Compared with Hanyuan-1, a 100-qubit neutral-atom quantum computing system, Hanyuan-2 features a 200-qubit dual-core system that enables computation and real-time error correction to be performed simultaneously.
Hanyuan-2 also delivers major breakthroughs over Hanyuan-1, boosting atomic manipulation accuracy from 90 percent to 99 percent and extending atomic stable survival time from 20 seconds to more than 100 seconds.
In addition, the system consumes under seven kilowatts of power and eliminates the need for cryogenic cooling, allowing reliable operation in standard laboratory environments.
The research and development team has also built an end-to-end production capability, covering the full value chain from chip manufacturing, packaging, and testing to laser modulation and phase-noise suppression, enabling domestic production of key core components.

At least 15 people were killed in a series of Israeli airstrikes in southern Lebanon on Saturday, according to Lebanese official sources.
At least one child was among those killed and several children were among those injured in the strikes, according to the Lebanese Health Ministry and the National News Agency.
The Israeli army on Saturday morning ordered residents of southern Lebanese towns to evacuate before conducting airstrikes and demolishing homes.
Israeli attacks and airstrikes in Lebanon since March 2 had killed 2,795 people and injured 8,586 others, according to the latest data released by the Emergency Operations Center of Lebanon's Ministry of Public Health on Saturday.
Meanwhile, Hezbollah said it launched a rocket barrage overnight targeting a gathering of Israeli military vehicles and soldiers along the Lebanon-Israel border, in response to Israeli violations of the ceasefire.
Hezbollah lawmaker Hassan Fadlallah said the group was in a "defensive position" against Israeli "aggression" and warned that Israel should expect a response whenever it targets Lebanese villages or Beirut's southern suburbs. An Israeli soldier was seriously injured, and two others moderately injured in Israeli territory near the Lebanese border by an explosive drone launched by Hezbollah on Saturday, according to a statement issued by the Israel Defense Forces (IDF).
The soldiers were rushed to a hospital, the statement said, adding that additional explosive drones launched by Hezbollah fell in Israeli territory near the border, without causing any casualties.
Another explosive drone hit an unmanned IDF engineering vehicle in southern Lebanon, with no casualties reported, the IDF said, adding that its air force intercepted several projectiles launched by Hezbollah toward Israeli soldiers operating in southern Lebanon.
The exchanges of fire came despite a ceasefire between Israel and Lebanon that took effect last month following weeks of cross-border fighting tied to broader regional tensions triggered by the U.S.-Israeli attacks on Iran.
