Researchers from Shibaura Institute of Technology, Waseda University, and Fujitsu have developed a quantum computing-based method to improve humanoid robot posture control by leveraging quantum entanglement. Their approach uses qubits to represent the position and orientation of robot joints, with entanglement mirroring the interconnected movement of real joints. By combining quantum circuits for forward kinematics with classical computing for inverse kinematics, the hybrid system reduces computational complexity, cutting errors by up to 43% and speeding up calculations compared to traditional methods. Tests on Fujitsu’s quantum simulator and a 64-qubit quantum computer confirmed these improvements, enabling realistic full-body movement calculations for robots with 17 joints that would otherwise require excessive computing power and time. This breakthrough is significant for the future of humanoid robots, especially those working closely with humans, as it enables smoother, more lifelike, and real-time motion control without oversimplifying joint models. The method is already compatible with current noisy intermediate-scale quantum (N
