- Physicists developed a quantum radar using Rydberg atoms to detect reflected radio waves for underground imaging.
- The radar uses a glass cell of cesium atoms, expanded to Rydberg state, to detect radio waves without large antennas.
- Rydberg atoms' sensitivity to various radio frequencies allows a single device to work across multiple frequency bands.
- The prototype radar was tested in a specially designed room, locating objects with an accuracy of 4.7 centimeters.
- Quantum sensors, like this radar, offer advantages such as identical components and less need for calibration.
- Governments are investing in quantum technologies, with potential crossover benefits between quantum sensors and quantum computing.
- Future improvements for the quantum radar include enhancing sensitivity to fainter signals and optimizing the device for specific compact applications.
