| Outline of Final Research Achievements |
We have investigated how hybrid quantum systems can enhance the sensitivity of the quantum sensors. We have studied the role of quantum entanglement to beat the standard quantum limit that every classical sensors are bounded by. Especially, we have discussed the use of superconducting circuits, electron spin, and nuclear spins to improve the sensitivity of the hybrid sensors. We have collaborated with experimentalists, and discuss how our theoretical ideas can be demonstrated in the current technology. Moreover, some of our ideas have been tested by the actual experiments. Our results contributes not only the realization of the sensors but also a milestone for the more advanced quantum applications such as quantum computation, quantum repeater, and quantum simulation. Therefore, we believe that our results are significantly important in this quantum information society.
