Quantum computing is rapidly advancing, presenting both opportunities and challenges. Researchers at Toshiba Europe have achieved a significant milestone by transmitting quantum-encrypted messages over a record distance of 254km using standard fiber optic cables. This breakthrough, facilitated by quantum key distribution (QKD) cryptography, marks the first instance of coherent quantum communication via existing telecom infrastructure. QKD leverages the principles of quantum mechanics to securely share encryption keys, making eavesdropping virtually impossible, as any attempt to intercept the message would immediately alert both parties involved.
This advance addresses growing concerns among European IT professionals, with 67% fearing that quantum computing could compromise current encryption standards. Unlike classical computers, which would take an impractical amount of time to break modern encryption, quantum computers can exploit phenomena like superposition and entanglement to potentially crack even the most secure classical encryptions within minutes. This has prompted global governments and organizations to accelerate the development of robust cryptographic algorithms capable of withstanding quantum attacks. Efforts are underway to build quantum-secure communication infrastructure. Heriot-Watt University recently inaugurated a £2.5 million Optical Ground Station (HOGS) to promote satellite-based quantum-secure communication. In July 2024, Toshiba Europe, GÉANT, PSNC, and Anglia Ruskin University demonstrated cryogenics-free QKD over a 254 km fiber link, using standard telecom racks and room temperature detectors. Initiatives such as Europe’s EuroQCI and ESA’s Eagle-1 satellite further underscore the commitment to developing and deploying quantum-resistant technologies, mitigating the silent threat that quantum computing poses to cybersecurity.

China is making significant strides in artificial intelligence, quantum computing, and robotics, signaling a growing technological prowess. Huawei is reportedly developing new AI chips, the Ascend 910D, aiming to rival Nvidia's high-end processors. These chips are undergoing testing with Chinese tech companies, and early samples are expected as soon as late May. This move aims to diminish reliance on foreign technology and support China's growing AI ambitions, especially given the restrictions placed on sales of advanced Nvidia products to China.
Chinese scientists have also made advancements in quantum technology with the development of a drone-mounted quantum sensor capable of detecting submarines. This sensor, utilizing a Coherent Population Trapping atomic magnetometer, addresses limitations of traditional magnetic anomaly detectors in low-latitude regions. Offshore trials near Weihai, Shandong province, demonstrated the system's high accuracy and stability in detecting minute changes in Earth's magnetic field, presenting possibilities for underwater resource mapping and military applications. Further testing in harsher conditions is needed before operational deployment. President Xi Jinping has emphasized the need for self-reliance in AI development. At a Politburo meeting, he called for increased support in research, talent training, and intellectual property protection. He also urged for strengthening basic research and key technologies like high-performance chips and basic software. Additionally, he pushed for expediting AI laws and regulations to ensure safety and control, highlighting China's commitment to closing the AI gap through homegrown innovation. Simultaneously, in the realm of robotics, China is emerging as a serious contender, demonstrated by the recent humanoid robot half-marathon, showcasing progress in humanoid robot technology and the country's manufacturing and engineering capabilities.
