Chinese scientists have successfully entangled 18 optical quantum bits, a key achievement that will dramatically promote quantum computing speed.
Entangling as many quantum bits as possible can lead to an exponential increase of quantum computing speed. However, scientists are facing a huge challenge to entangle a large amount of quantum bits.
A group of Chinese scientists for the first time entangled as many as 18 quantum bits by adopting a new technology called the multi-degrees of freedom photon control method.
“If I can control the three degrees of freedom of a photon, then it’s equivalent to triple it. The control of multi-degrees of freedom is another effective approach for us to further increase the number of the controllable quantum bits. We have adopted multiple approaches at the same time to achieve the large-amount quantum bits entanglement,” said Lu Chaoyang, professor with the University of Science and Technology of China.
Lu added that this achievement can be used in large-scale, high-efficiency quantum information technology, and can be regarded as a milestone in the technology’s development.
“Our next plan is to surpass the conventional computers using integrated circuits in human history, then surpass the fastest commercial computers of our times, and then surpass the supercomputers. This is our fundamental plan,” said Lu. — Reuters
BEIJING – China has lifted import restrictions on poultry products from the United States after nearly five years, according to the General Administration of Customs and the Ministry of Agriculture.
In January 2015, China banned the import of chicken and poultry products from the US to protect itself from bird flu that had been recorded in some areas of America in 2013 and 2014.
According to a joint statement by the two Chinese bodies, the US took active and preventive measures following the bird flu outbreak, and that no fresh cases had been reported since March 2017.
A team of Chinese experts visited the US in July 2017 on Washington’s invitation to conduct on-the-spot assessments of measures against bird flu, the statement said.
In May 2018, the two countries held consultations on the subject, and after a full assessment, China considered the bird flu epidemic in the US to be effectively under control, and poultry regulation systems were compliant with Chinese legal requirements.
The statement said that following the lifting of US import restrictions, Chinese poultry imports would expand to effectively respond to market demands.
According to US trade authorities, the end of the import ban would result in the export of poultry products worth more than $1 billion to China annually.
Moreover, China has been facing a meat shortage following an outbreak of African swine fever, which has led to the culling of millions of pigs in the country, affecting the supply of pork, a preferred food item among the Chinese. – EFE-EPA
Vice President Leni Robredo who is also the co-chairman of the government’s anti-illegal drug program, said that the majority of the illegal drugs in the country came from China.
After the Inter-agency Committee on Anti-Illegal Drugs (ICAD) Enforcement Cluster Meeting on Thursday (November 14), Robredo said this is based on the reports they currently have.
“Kasi iyong pinaka-report talaga sa atin ngayon, karamihan sa supply na pumapasok dito, galing China. Pati iyon mga nahuhuli sa ma nago-operate within the Philippines, karamihan Chinese nationals or Filipino-Chinese national (Because based on the reports we have, most of the supply entering the country came from China. Even those who are arrested for operating in the Philippines, most of them are Chinese nationals or Filipino-Chinese nationals),” she said.
The vice president also said she wants to collect more data and review the information they have gathered regarding the supply of illegal drugs entering the country.
However, according to the Philippine Drug Enforcement Agency (PDEA) Chief Aaron Aquino the drugs entering the country came from the Golden Triangle Drug Syndicate.
The Golden Triangle, Aquino said, is an area on the border of Thailand, Myanmar, and Laos.
Aquino added that due to the crackdown of illegal drugs in China, drug syndicates in the said country opted to get their supply from other places instead of manufacturing it.
Meanwhile, Robredo also plans to coordinate with other countries including the United States regarding the drug war in order to strengthen the government’s campaign against illegal drugs.—AAC (with reports from Vincent Arboleda)
MANILA, Philippines – Reports of China’s 40% ownership of the National Grid of the Philippines (NGCP) has been on the headlines recently as several senators claimed it would pose threats to national security.
But according to a legal expert, Atty. George Erwin Garcia, the Constitution actually allows foreign entities to have shares in government-owned corporations such as the NGCP.
“From the Constitutional point of view, everything is perfectly legal. So, there is nothing illegal,” Garcia, Dean of the College of Law in Pamantasan ng Lungsod ng Maynila, said.
“There is nothing unconstitutional (with the) 40% Chinese ownership of the National Grid Corporation,” he added.
Senators Ralph Recto and Francis Pangilinan recently raised concerns about possible Chinese manipulation in the Philippines’ power grid given the rights China has on its shares.
Under Article 12 of the 1987 Constitution, foreign ownership is allowed provided that 60% of the company’s shares are owned by a Filipino.
Garcia noted, however, that when it comes to security, the NGCP has to make sure that China has no control of the operations and administrations of their facility.
The law also dictates that the foreign investor only has limited rights on the company and the state, which is the Philippine government, still has the full authority of the facility’s full operation.
“Dapat siguraduhin nila, 60-40 ang arrangement (They have to make sure that indeed the arrangement is 60-40). Forty percent nga Chinese pero baka naman ang 60, nasa likod Chinese rin (It might be 40% Chinese but it could be that those behind the other 60% are Chinese as well),” Garcia said.
“Baka naman sila’y naka-front lang for the Chinese o baka naman sila ay tinatawag nating “dummies” for the Chinese. Huwag naman sanang mangyari ‘yun (They could be fronting for the Chinese or like dummies for the Chinese. It must not be that way),” he added.
Senator Sherwin Gatchalian, chairman of the Senate Committee on Energy, previously stated that Chinese experts may provide technical assistance for the NGCP but only Filipinos can manage the entire facility.
In 2015, the Department of Energy (DOE) announced that it would no longer renew the working visas of 18 Chinese experts working then at the NGCP.
But in 2017, NGCP sent 26 engineers and technical staff for training in China to prepare them for much bigger projects.
Despite the issues, the NGCP maintained that the Chinese investors are only up for investments and business tying up with the state-run power grid. MNP (with reports from Harlene Delgado)
