The provided text examines the implications of quantum radar for stealth aircraft technology, arguing that the emergence of Quantum Illumination (QI) could render conventional stealth obsolete. It details how QI leverages quantum entanglement to detect targets by correlation rather than signal strength, making it immune to traditional jamming and spoofing. However, the text also critically assesses the significant engineering and operational hurdles facing quantum radar, such as limited range and fragile quantum states. Finally, it proposes future countermeasures, including "quantum stealth" materials and revised tactical doctrines, to ensure aircraft survivability in a future where invisibility may no longer be a viable defense.
