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

PH gov’t to verify reports on foreign ships’ alleged sewage dumping in West Philippine Sea

Robie de Guzman   •   July 14, 2021


MANILA, Philippines — The Philippine government will look into a report that some foreign vessels were allegedly dumping sewage wastes in the contested parts of the West Philippine Sea, Malacañang said Wednesday.

Presidential Spokesperson Harry Roque issued the statement in response to a report released by US-based geospatial imagery firm, Simularity, which stated that foreign ships have been dumping sewage and human wastes in the reefs of the disputed waters.

“The responsible answer is we are verifying first, we will react if it’s been verified,” Roque said in a press briefing.

“We should accord our neighbors, and our friends the presumption of good faith, when they say something about an issue,” he added.

If the reports are true, Roque said the government would never allow the Philippines to become a garbage dump.

He even cited the incident when the Philippines sent back to Canada its illegally exported trash in 2019.

The Department of National Defense earlier said it is already verifying the report as it noted that the photo accompanying it was supposedly taken on the Australian Great Barrier Reef in 2014.

DFA urged to summon Chinese envoy over additional ships spotted in WPS

MANILA, Philippines — Senator Risa Hontiveros on Wednesday called on the Department of Foreign Affairs (DFA) to summon Beijing’s Ambassador to Manila anew over the reported presence of more Chinese ships within the Philippines’ exclusive economic zone (EEZ) at the West Philippine Sea.

Hontiveros said the DFA should ask China’s envoy to explain the alleged presence of more than 100 ships this month as reported by a geospatial intelligence firm.

According to a report released Sunday by US-based Simularity, the number of “likely Chinese ships” spiked from 129 to 238, an increase of over 100 ships.

The report detailed that “between mid-May and mid-June 2021, the number of ships within the Union Banks increased from 9 to 236 and the number of ships near Gaven (Burgos) Reef in Tizard Bank decreased from 234 to 71.”

“Instead of de-escalating the tensions in the disputed waters, they doubled down. This clearly shows that China is shamelessly hellbent on aggravating the situation,” Hontiveros said in a statement.

She also urged Malacañang to condemn China’s “incessant presence” in the West Philippine Sea.

“The Palace should look Beijing straight in the eye and tell her to remove her ships from our territories,” she said.

As of writing, the DFA has yet to issue a statement on the matter.

Two months ago, the DFA summoned Chinese Ambassador Huang Xilian for the first time over Beijing’s continued swarming of Julian Felipe Reef with over 200 of its vessels.

China has ignored the arbitral ruling that invalidated its nine-dash claim over the vast part of the South China Sea, including parts of the West Philippine Sea.

The DFA has repeatedly fired off diplomatic protest and called for the immediate withdrawal of the vessels.

Duterte, Xi call for ‘win-win’ cooperation on 46th anniversary of PH-China ties

MANILA, Philippines—President Rodrigo Duterte and Chinese President Xi Jinping both call for a “win-win” cooperation in commemoration of the 46th anniversary of Philippine-China relations.

The Philippine President expressed his gratitude for  China’s assistance to the Philippines in the face of challenges brought by the COVID-19 pandemic.

“Philippine-China economic ties are of course the dynamic force that will continue to drive or bilateral relations forward,” Duterte told Xi in a statement.

“I am confident that my Administration’s Build Build Build program together with the Belt and Road Initiative, will reap long-term benefits for our peoples,” he added.

Meanwhile, in a letter addressed to Duterte, the Chinese president acknowledged that in recent years, with concerted efforts of both sides, Philippine- China relations have remained “healthy and stable.”

“I attach great significance to the development of China-Philippines relations, and stand ready to work with you in guiding our bilateral relations to move forward in a sustained and steady manner, so as to achieve greater win-win results and mutual benefits,” Xi said. AAC
