Traditional navigation systems, like GPS, rely on classical physics and can be susceptible to disruptions and inaccuracies in space. Quantum sensors introduce a revolutionary approach to navigation by utilizing quantum properties of atoms. Quantum atomic clocks and accelerometers, operating on the principles of superposition and entanglement, provide extreme precision in measuring time and acceleration. These sensors aid spacecrafts in navigating autonomously with unparalleled accuracy, reducing reliance on external signals or beacons. Quantum navigation thus enhances the efficiency and safety of space missions, offering a significant leap forward in precise positioning in the vastness of outer space.
