Systems and methods of quantum sensing include depositing a sample volume onto an ensemble of quantum defects, hyperpolarizing spins in the sample volume, performing a sensing sequence, and reading out information regarding electronic spin states of the quantum defects in the ensemble of quantum defects, which sense the hyperpolarized spins in the sample volume.

Systems and methods for quantum sensing with signal amplification by reversible exchange

Systems and methods of quantum sensing include obtaining information regarding a target signal in electronic spin states of quantum defects in an ensemble of quantum defects, mapping 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, applying a light pulse to the ensemble of quantum defects to reset the electronic spin states of the quantum defects, and repeating a readout stage a plurality of times within a readout duration. The readout stage includes mapping the information regarding the target signal back from the nuclear spin states to the corresponding electronic spin states and applying a data acquisition readout pulse to optically measure the electronic spin states of the quantum defects.

Multi-color CL images of nanoparticle samples may be generated, by irradiating with a scanning electron beam a nanoparticle sample that containing a plurality of spectrally distinct optical emitters configured to generate CL light at respective different color channels, then detecting the CL light from the nanoparticles to generate multi-color NP-CL images of the nanoparticle sample. In some embodiments, SE (secondary electron) images of the sample may be acquire, substantially simultaneously with the acquisition of the CL images, so as to generate correlative NP-CL and SE images of the nanoparticle sample. In some embodiments, the nanoparticles may be surface-functionalized so that the nanoparticles selectively bind only to particular structures of interest.
