The Micius satellite’s QKD system, designed for secure communication, faces vulnerabilities due to laser timing flaws. A 300 ps delay allows eavesdroppers to distinguish signal and decoy states, nullifying security. Enhanced testing and synchronization are critical for future systems.
The FCC’s new National Security Council is changing how the United States addresses telecom risks. Chairman Brendan Carr introduced the council on March 13, 2025, amid rising concerns over foreign infiltration. Quantum computing remains at the forefront, as it could weaken current encryption methods. Here we look through the lens of quantum computing at this new Council.
Chinese scientists have introduced “Zuchongzhi 3.0,” a 105-qubit superconducting quantum computer, marking a major step in quantum research. The system vastly outperforms classical supercomputers and strengthens China’s position in the global quantum race. Researchers see potential in materials science, cryptography, and scalable quantum technologies.
WiMi Hologram Cloud Inc. shares a plan for digital quantum coprocessors using FPGAs. The approach adapts qubit operations into programmable logic. Homogeneous and heterogeneous structures support varied workloads with enhanced stability.
MicroAlgo Inc. presents a new arithmetic method in quantum gate computing. The design uses CPU registers to handle qubits for addition tasks. This approach draws on the Bernstein-Vazirani algorithm for more efficient operations.
China Mobile and China Electronics Technology Group Corp have introduced China’s biggest quantum computing cloud platform.
The Facility Location Problem, or FLP, is a long-standing challenge within operations research—the application of scientific methods to decision-making and problem-solving by managers in large commercial, public or military organizations.
Let’s pump the brakes on the quantum panic. Yes, these research findings are potentially a big deal for national security purposes.
The United States may be poised to open a new front in its effort to block China’s access to our high-tech base, namely quantum computing.
[I]t was China that launched the first quantum satellite in 2016, dubbed Micius, and a year later used it to establish how to achieve long-distance QKD communication… So where is the U.S. in all this?
