Quantum-enhanced artificial potential field method for robust drone swarm shape formation
This paper introduces the Quantum-Enhanced Artificial Potential Field (QEAPF) method, a novel hybrid approach that combines quantum-inspired probabilistic discovery mechanisms with Artificial Potential Field (APF) techniques to enhance drone swarm shape formation. QEAPF significantly improves formation convergence time, path efficiency, and disturbance rejection capabilities. Simulations show up to a 37% improvement in convergence time and a 42% reduction in operational disruptions compared to traditional APF, while maintaining collision avoidance, energy efficiency, and geometric integrity.

The Quantum-Enhanced Artificial Potential Field (QEAPF) method is a novel hybrid approach that merges the deterministic nature of Artificial Potential Field (APF) algorithms with the probabilistic exploration capabilities of quantum-inspired optimization. This combination allows for faster convergence to optimal formations while ensuring robustness against environmental disturbances. The method guides drones from initial to desired positions, achieving target formations with minimum time, collision avoidance, and optimal path length. It integrates attractive, repulsive, formation-maintaining, and disturbance-compensating potential fields, alongside a quantum-inspired optimization technique and an adaptive parameter adjustment mechanism.
Inspired by quantum computing principles, the QEAPF algorithm represents each drone's state as a qubit in a two-dimensional Hilbert space. State 0 signifies exploitation towards the best local position, ensuring convergence, while State 1 represents exploration into new areas, helping to avoid local minima. Probability amplitudes are dynamically updated via a quantum rotation gate, balancing exploitation and exploration based on the drone's performance relative to local and global bests. This probabilistic measurement introduces controlled stochasticity, aiding in escaping local minima while maintaining overall convergence, differing from purely random exploration by systematically evolving coherent quantum states based on formation progress.
QEAPF explicitly addresses external disturbances through an adaptive time-weighted matrix (Wi) and a disturbance-compensating potential (Ud). This mechanism penalizes deviations from desired positions and allows each drone to learn and counteract persistent disturbances. The estimated disturbance is derived using a recursive least squares (RLS) filter, similar to a Kalman filter. This allows for active compensation, adjusting control gains online to strengthen forces when collision risk or formation error increases, thereby maintaining system stability and robustness even under persistent environmental fluctuations.
The QEAPF method employs several adaptive parameter tuning mechanisms to enhance formation speed and robustness. These include attractive gain (kf) adapting based on formation progress, repulsive gains (kc, ko) adjusting based on collision risk (inter-drone and drone-obstacle distances), and disturbance compensation gain (kd) adapting based on the estimated disturbance magnitude. These adaptive adjustments ensure that forces strengthen proportionally to collision risk or formation error, and quantum exploration is balanced with exploitation, leading to robust trajectory tracking and dynamic formation maintenance.

Real-world Application: Traffic Surveillance
In traffic surveillance, drone swarms require robust shape formation and disturbance rejection to maintain optimal coverage and track targets effectively. Traditional APF methods struggled with maintaining formation integrity under varying wind conditions or sudden maneuvers, leading to gaps in coverage or collisions. With QEAPF, a swarm of 5 drones can adapt dynamically to maintain its V-formation even with strong gusts (0.5m disturbances), ensuring continuous and reliable surveillance. The quantum-inspired exploration helps the swarm quickly reconfigure and avoid local minima when navigating complex urban environments with tall buildings.
This results in 37% faster deployment for critical surveillance tasks and a 42% reduction in operational disruptions due to environmental factors, significantly improving data capture and incident response times.
