Abstract

This paper investigates the quantum advantage in transportation tasks, comparing quantum and classical projectiles and rockets. It finds that ultrafast and ultraslow quantum states exist, exceeding or falling short of classical arrival probabilities. The maximum quantum advantage is linked to the Bracken-Melloy constant (Cbm), with bounds established as 0.0315 ≤ Cbm ≤ 0.072. A modified scenario, constraining initial position distribution, demonstrates a quantum advantage reaching 0.1262.
