Quantum Sensors

Choose the Correct Answer

Correct Answer : Option b

Explanation
Correct Option (b): They provide highly precise navigation without GPS.
Quantum sensors, especially atomic interferometers and quantum gyroscopes, can measure changes in motion and gravity with extreme precision. This allows spacecraft to navigate autonomously without relying on GPS or external signals, which is crucial for deep-space missions. Quantum inertial sensors help maintain precise positioning even in areas where traditional systems are ineffective.

Other incorrect options:
Option (a): Gravitational wave detection typically requires large-scale interferometers (like LIGO and LISA) rather than quantum sensors on spacecraft.
Option (c): Data transmission across planets depends on radio waves, lasers, and optical communication systems, not quantum sensors.
Option (d): Quantum sensors do not generate power.
