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

China has made key technological breakthroughs in developing its Tiangong Space Station, as announced at the 5th Manned Space Conference, which opened on Tuesday in Xi’an, the capital city of northwest China’s Shaanxi Province.

The Tianhe core capsule of the space station will exhibit in full size at the upcoming 12th Zhuhai Airshow which runs from Nov 6-11.

The China-developed space station consists of a core capsule and two experiment modules. It can hold three astronauts and a maximum of six during change of the crew members.

China has long been making preparations for constructing and launching the space station. For example, it will launch the Long March-5B carrier rocket into space in 2019 to help carry the core module and experiment modules to the space station.

“Currently, we are making steady progress in the space station research and construction. Key technological breakthroughs have been made in producing the three modules including the core capsule and the Long March-5B carrier rocket. Selection of the third batch of reserve astronauts is also underway as scheduled,” said Hao Chun, director of China Manned Space Engineering Office.

The space station will enable experiments in multiple areas, including space science, biological technologies, and microgravity fundamental physics and materials sciences in space.

“We will complete on-orbit construction of the space station around 2022 as planned. It will be a national orbital space lab in the long run after being completed,” Hao said. — Reuters

Without ICC treaty, PHL can’t sue China if it invades Panatag, Scarborough — Carpio

MANILA, Philippines — The Supreme Court has concluded the oral arguments on the petition questioning the validity of the country’s withdrawal from the International Criminal Court (ICC).

It was the Executive Department’s turn to argue that there is no explicit constitutional provision that states Senate concurrence is required in treaty withdrawal.

Solicitor General Jose Calida explained that President Rodrigo Duterte did not violate the Constitution, but only exercised his power as the chief architect that crafts and implements foreign policy.

But Justice Antonio Carpio said the ICC treaty is the only legal deterrent that can protect the country from China’s abuses, specifically, the Kampala Amendment which activated the court’s jurisdiction on crimes of aggression.

“If China invades Pag-asa [Island] and puts up a naval base in Scarborough Shoal, we will not be able to sue President Xi Jin Ping and his military leaders because we have withdrawn already from the ICC, correct?
I mean we cannot take advantage of this legal defense anymore because we are withdrawing from the Rome Statute.

Calida suggested that there might be other international treaties that can be used, but Carpio insisted otherwise.

“This is the only treaty in the world that holds political and military leaders of a state that commits the crime of aggression,” Carpio said.

The Philippines withdrew from the treaty in March 2018 via note verbale sent to the United Nations amid the preliminary examinations on Duterte’s war on drugs by ICC prosecutor Fathou Bensouda.

But according to constitutional law professor Tony La Viña, whether or not the high court rules in favor of the president, investigations on his controversial drug war will continue.

“Kahit sabihin ng Supreme Court natin na valid ang pag withdraw ni Duterte di ba? For any case filed against him, for acts he committed noong member pa tayo, continue iyon. Ang consequence lang ng pagwithdraw natin sa ICC ay any acts committed after April or March, when it takes effect, is no longer covered,” La Viña said.

The petitions asking for the nullification of the withdrawal were filed by opposition senators and the Philippine Coalition for the International Criminal Court. — Mai Bermudez

MANILA, Philippines — The government believes that the possible joint oil exploration between the Philippines and China in the West Philippines Sea will help address surging oil prices and ensure the country’s energy security.

The government is eyeing to sign a formal agreement with China during President Xi Jinping’s visit to the country this year.

However, Malacañang clarified that the agreement will not be immediately implemented pending processes and studies to be undertaken on the matter.

“That’s why we are studying it and the administration is pushing for the joint exploration in the West Philippine Sea because based on the initial study, there is natural gas or diesel especially in what we call the Service Contract No. 72,” said Presidential Spokesperson Sec. Harry Roque. — Rosalie Coz | UNTV News & Rescue
