CPC G01N 24/006 (2013.01) [G01N 24/08 (2013.01); G01N 33/381 (2013.01)] | 20 Claims |
15. A quantum sensor, comprising:
an ensemble of quantum defects; and
at least one controller including at least one processor and at least one associated memory storing instructions to be executed by the processor to cause the at least one controller to:
direct application of a sensing sequence of energy pulses to the ensemble of quantum defects to obtain information regarding a target signal in electronic spin states of quantum defects in an ensemble of quantum defects;
direct application of a microwave (MW) pulse and a radio frequency (RF) pulse to the ensemble of quantum defects to map the information regarding the target signal from the electronic spin states of the quantum defects to corresponding nuclear spin states associated with the quantum defects;
direct application of a light pulse to the ensemble of quantum defects to reset the electronic spin states of the quantum defects; and
direct repetition of a readout stage a plurality of times within a readout duration, wherein, in the readout stage, the at least one controller is caused to:
direct application of an MW pulse to the ensemble of quantum defects to map the information regarding the target signal back from the nuclear spin states to the corresponding electronic spin states; and
direct application of a data acquisition readout pulse to the ensemble of quantum defects to optically measure the electronic spin states of the quantum defects.
