A Chinese telecom service provider rolled off its first quantum-encrypted smartphone on Monday, a day before the World Telecommunication and Information Society Day.

Launched by China Telecom, Tianyi No. 1 2022 is a smartphone mounted with a quantum-secured encryption module and purpose-built SIM card that can encrypt and decipher voice calls on the phone using the quantum key distribution, the company said.

The telecom giant and the startup QuantumCTeck set up a joint venture in 2021 to develop quantum-based communication and bring the ingenious know-how to the market.

Chinese scientists, some of whom were part of the founding team of QuantumCTeck, tested the quantum key distribution with the world’s first quantum satellite Micius launched in August 2016.

Unlike traditional cryptography, the technology uses single photons in quantum superposition states by which the key is embedded to guarantee unconditional security between distant parties.

Quantum superposition is a fundamental principle of quantum mechanics, which stipulates that much like waves in classical physics, any two or more quantum states can be added together.

The communication is, therefore, “unhackable” as any attempt to intercept the key would be known immediately both to the sender and the intended recipient.

“When a user initiates a quantum-secured chat, a secret key will be generated at random to verify his or her identity,” said Zhang Rutong, an engineer with QuantumCTeck. “After verification, the quantum network will generate a new real-time key to encrypt voice data.”

“The key is randomly generated, hard to crack and discarded immediately after calling,” Zhang added.

China Telecom had launched a pilot program to test out quantum encrypted Voice over IP (VoIP) calls via specially designed SIM card and smartphone app in January 2021. The newly launched smartphone can realize Voice over LTE (VoLTE) to deliver high-quality voice calls and text messages.

The service is available when both senders and recipients use the quantum-based phone, and the product prototypes are now in the market for testing in some regions across China, the company said.

BERLIN, Sept. 1 (Xinhua) — As one of the world’s leading trade fairs for consumer electronics, the five-day IFA 2023 opened here on Friday with over 2,000 exhibitors from 48 countries and regions, a much greater scale than last year.

“In addition to all the historic brands you know and love at IFA, 30 percent of exhibitors are new this year,” Oliver Merlin, managing director of IFA Management, said in a statement issued on Friday.

According to the organizer, sustainability is a major priority of the trade fair. Ahead of IFA’s 100th birthday next year, the 2023 event for the first time dedicated an exhibit area to highlighting sustainability. Besides, it will have multiple forums to discuss how consumer electronic enterprises could develop in a more sustainable approach.

According to IFA official website, nearly 1,300 Chinese exhibitors have registered in this year’s event. Chinese companies such as Hisense, TCL and Haier have occupied some of the largest exhibit areas with various products.

While delivering a keynote speech on Friday, Hisense Group’s President Yu Zhitao said the company looks forward to expanding its overseas market share.

“In order to be more and more user-centric, we are upgrading and optimizing our products and services to meet consumer needs,” he said.

The inaugural International Congress of Basic Science (ICBS) took place in Beijing on Sunday with a theme of “Advanced Science for Humanity.”

The conference lasts two weeks, with over 800 top-notch scientists and scholars gathering to discuss frontier research in the fields of mathematics, theoretical physics, theoretical computer and information science.

Shing-Tung Yau, president of the International Congress of Basic Science and a Fields Medal winner, said in the opening speech that he is expecting the academic exchanges at the conference to contribute to the development of the world’s basic science knowledge. “I hope the renowned international scholars learn more about China and the young scholars learn from the best and set their goals.”

The scientists attending the conference include eight Fields Medal winners, four Turing Award winners, one Nobel Prize laureate and more than 50 academicians from different countries.

The conference is hosted by the People’s Government of Beijing Municipality, the Ministry of Science and Technology of China, China Association for Science and Technology, and the International Consortium of Chinese Mathematicians.

European Space Agency launches Jupiter moons explorer

PARIS, April 14 (Xinhua) — The European Space Agency (ESA) launched on Friday an Ariane 5 rocket carrying its Jupiter Icy Moons Explorer (Juice) from Europe’s Spaceport in French Guiana.

According to the ESA, the successful launch marks the beginning of an ambitious voyage to uncover the secrets of the ocean worlds on Jupiter’s three largest moons: Europa, Ganymede, and Callisto, which hold quantities of water under their surfaces in volumes far greater than in Earth’s oceans.

“These planet-sized moons offer us tantalizing hints that conditions for life could exist other than here on our ‘pale blue dot’,” the ESA said in its press release.

Over the next two-and-half weeks, Juice will deploy its various antennas and instrument booms, including a 16-meter-long radar antenna, a 10.6-meter-long magnetometer boom, and various other instruments that will study the environment of Jupiter and the subsurface of the icy moons, the agency said.

Juice will also monitor Jupiter’s complex magnetic, radiation, and plasma environment in depth and its interplay with the moons, thus studying the Jupiter system as an archetype for gas giant systems across the Universe.

Juice has been designed for an eight-year cruise with flybys of Earth and Venus to slingshot it to Jupiter. It will make 35 flybys of the three large moons while orbiting Jupiter, before changing orbits to Ganymede, said the agency.
