Recent advances in quantum computing highlight both technological progress and emerging security challenges. Researchers have developed physics-inspired encryption methods designed to protect data against both classical and quantum attacks, enabling confidential computing without exposing raw information. A notable breakthrough was reported by XanaduAI, which demonstrated the world's first error-resistant photonic qubits on an integrated chip, marking a key milestone for scalable quantum hardware. Meanwhile, Google Quantum AI and collaborators simulated lattice gauge theory and visualized string dynamics, contributing to the understanding of particle physics forces. Physicists at MIT observed a new form of magnetism in nickel iodide, termed p-wave magnetism, which could lead to energy-efficient spintronic devices. However, concerns about quantum computing's impact on cybersecurity are growing; a new estimate from Google Quantum AI researcher Craig Gidney suggests that a quantum computer with fewer than one million noisy qubits could break 2048-bit RSA encryption in about a week, making the threat more imminent than previously thought. Additionally, quantum startup Infleqtion raised $100 million to develop quantum technologies for defense applications. While some claims about quantum computing's immediate military use have been met with skepticism, the technology's potential to revolutionize encryption and computing remains clear.
