Academia Sinica yesterday unveiled a quantum computer based on 5-quantum-bit (qubit) chips, connecting the device to the Internet to enable its use in scientific research by the institution’s members and partners.
The computer’s launch marked another milestone in the nation’s research into and development of quantum computing following the chip’s creation in October last year, said Chen Chii-dong (陳啟東), a research fellow at Academia Sinica’s Research Center of Applied Sciences.
Researchers participating in the Ministry of Science and Technology’s project accomplished the objectives ahead of the ministry’s schedule, which had stipulated the development of 3-qubit chips by February last year, he said.

The Taiwanese quantum computer’s logic gate reached a 99.9 percent fidelity rate, he added.
Although great strides have been and are being made in quantum computing technology, there is still a long way to go for its practical application in the commercial sector or for personal use, Academia Sinica said.
The 5-qubit computer is now available for use as a test and development platform for quantum computing, ultra-low temperature complementary metal oxide semiconductor (CMOS) and operational amplifier research programs, it said.
The Taiwanese research team has consistently outperformed expectations despite being given less time and resources than the quantum computer research programs of foreign nations, Academia Sinica President James Liao (廖俊智) said.
The program’s successful achievements are a basic part of the technology, and researchers need time to resolve foundational problems before breaking through the next bottleneck, he said.
Academia Sinica’s work in quantum computing is intended to blaze a trail for the nation’s private sector and generate the momentum necessary to sustain the investment in talent and education, Liao said.
Taiwan’s quantum computing project is a collaboration between Academia Sinica, the Industrial Technology Research Institute, National Changhua Normal University, National Central University, National Chung Hsin University, the University of California, Santa Barbara and the University of Wisconsin-Madison, it said.
The Ministry of Transportation and Communications yesterday inaugurated the Danjiang Bridge across the Tamsui River in New Taipei City, saying that the structure would be an architectural icon and traffic artery for Taiwan. Feted as a major engineering achievement, the Danjiang Bridge is 920m long, 211m tall at the top of its pylon, and is the longest single-pylon asymmetric cable-stayed bridge in the world, the government’s Web site for the structure said. It was designed by late Iraqi-British architect Zaha Hadid. The structure, with a maximum deck of 70m, accommodates road and light rail traffic, and affords a 200m navigation channel for boats,
PRECISION STRIKES: The most significant reason to deploy HIMARS to outlying islands is to establish a ‘dead zone’ that the PLA would not dare enter, a source said A High Mobility Artillery Rocket System (HIMARS) would be deployed to Penghu County and Dongyin Island (東引) in Lienchiang County (Matsu) to force the Chinese military to retreat at least 100km from the coastline, a military source said yesterday. Taiwan has been procuring HIMARS and Army Tactical Missile Systems (ATACMS) from the US in batches. Once all batches have been delivered, Taiwan would possess 111 HIMARS units and 504 ATACMS, which have a range of 300km. Considering that “offense is the best defense,” the military plans to forward-deploy the systems to outlying islands such as Penghu and Dongyin so that
WHAT WAS ALL THAT FOR? Jaw Shaw-kong said that Cheng Li-wen had pushed for more drastic cuts and attacked him, just for the outcome to be nearly identical to his bill The legislature yesterday passed a supplementary budget bill to fund the purchase of separate packages of US military equipment, with the combined amount of spending capped at NT$780 billion (US$24.8 billion). The Chinese Nationalist Party (KMT) and Taiwan People’s Party (TPP) used their legislative majority to pass the bill, which runs until 2033 and has two main funding provisions. One was for NT$300 billion of arms sales already approved by the US for Taiwan on Dec. 17 last year, the other was for NT$480 billion for another arms package expected to be announced by Washington. The bill, which fell short of the NT$1.25
‘CLEAR MESSAGE’: The bill would set up an interagency ‘tiger team’ to review sanctions tools and other economic options to help deter any Chinese aggression toward Taiwan US Representative Young Kim has introduced a bill to deter Chinese aggression against Taiwan, calling for an interagency “tiger team” to preplan coordinated sanctions and economic measures in response to possible Chinese military or political action against Taiwan. “[Chinese President] Xi Jinping [習近平] has directed the People’s Liberation Army to be ready to invade Taiwan by 2027. China has a plan. America should have one too,” Kim said in a news release on Thursday last week. She introduced the “Deter PRC [People’s Republic of China] aggression against Taiwan act” to “ensure the US has a coordinated sanctions strategy ready should
