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

Hong Kong residents relieved as clean up continues after super typhoon

Workers in Hong Kong continued the cleanup and repair operation on Tuesday (September 18) after a typhoon, dubbed the “King of Storms”, struck over the weekend.

Super typhoon Mangkhut, with hurricane-force winds well over 200 kilometers per hour (124 miles/h), barreled past the northern tip of the Philippines, killing at least 54 people. It then skirted south of Hong Kong and the neighboring gambling hub of Macau, before making landfall in China.

The city has been trying to clear scores of felled trees and bamboo scaffolding which have been blocking roads and on Monday contributed to severe disruption to commuters. Some buildings, including the One Harbourfront office tower, had many windows smashed after a day in which some of the city’s skyscrapers had swayed with the ferocious gusts.

Residents said they were relieved that public transportation has resumed.

The China Meteorological Administration said Mangkhut was one of the 10 biggest storms to hit southeast China since 1949 – when records began – with wind speeds at around 162 km/h. — Reuters

Chinese President Xi Jinping on Monday extended condolences to his Philippine counterpart Rodrigo Duterte over Typhoon Mangkhut that has hit the Philippines, killing some 65 people.

In his message to Duterte, Xi said the typhoon has caused severe casualties and loss of properties in the Philippines. On behalf of the Chinese government and people, and in his own name, Xi mourned the victims and expressed sympathy to those injured, the bereaved families and the people in the affected area.

Xi said that China and the Philippines are friendly neighbors, and the Chinese people shared the sadness of the Philippine people over their sufferings, and are willing to help as much as possible.

Xi added that he believed that under the leadership of President Duterte and the Philippine government, the Philippine people will quickly overcome the disaster and rebuild their homeland. — Reuters

Typhoon Mangkhut, the strongest storm in 2018, slammed into south China’s Guangxi Zhuang Autonomous Region at late Sunday, after making landfall in neighboring Guangdong Province earlier in the day.

Moving at a speed of 33 kilometers per hour, Typhoon Mangkhut moved into Guangxi from Yulin City at around 23:00, packing strong winds and bringing heavy rains.

Powerful winds ripped branches off many trees and knocked over traffic barriers and trash bins in a local street.

The typhoon also cut off power supply in some neighborhoods in the city.

Guangxi initiated an emergency response on Friday, two days before the typhoon landed. As of 23:00 Sunday, more than 250,000 people have been transferred to safe places.

The regional education department has ordered all schools in nine cities to close for Sunday and Monday, and the fire department has dispatched 500 firefighters and 130 fire engines to Yulin and Beihai cities.

The regional power authority has put 14,000 staff members on standby and prepared over 1000 power generating facilities in case of more blackouts.

The local railway has closed some routes, suspended train services to Yulin City. Passenger service vehicles and freight vehicles have also been suspended. Some of the highways have been closed while others will be subject to traffic control starting from 23:00 Sunday night. — Reuters
