Quantum sensors are a new upcoming technology that offers to push the limits of how we can detect incredibly small signals in the DC and low RF regimes using magnetometers such as super-conducting quantum interference device (SQUID); N-V centres in Diamond, atomic vapour cells and atomic traps. All these technologies are currently being heavily invested in to push the boundaries of magnetometry for commercial applications. The quantum sensor I have been working to develop is set apart in several different aspects: unlike other quantum sensors it is very sensitive at the high RF and even 12.6 GHz microwave radiation; it has the ability to be rapidly tuned to different frequencies; due to the microwave decoupling technique we employ, the sensor is not sensitive to fluctuations in the DC field and therefore does not require bulky shielding or a laboratory environment to function. To this end I have built a demonstrator system capable of sensing RF and microwave fields and have measured the sensitivity of this device in both of these regimes. There has also been work on developing a portable version of the demonstrator and this work is ongoing within the group.
