High-sensitivity double-quantum magnetometry in diamond via quantum control
文献摘要：
High-fidelity quantum operation of qubits plays an important role in magnetometry based on nitrogen-vacancy (NV) centers in diamonds. However, the nontrivial spin-spin coupling of the NV center decreases signal contrast and sens-itivity. Here, we overcome this limitation by exploiting the amplitude modulation of microwaves, which allows us to per-fectly detect magnetic signals at low fields. Compared with the traditional double-quantum sensing protocol, the full con-trast of the detection signal was recovered, and the sensitivity was enhanced three times in the experiment. Our method is applicable to a wide range of sensing tasks, such as temperature, strain, and electric field.
