A novel and useful multistage semiconductor quantum detector circuit incorporating an anticorrelation mechanism. The quantum structure has at least the first stage sensor of the detector merged into the quantum structure in order to minimize loading of the quantum structure. The merged quantum structure and detector sensor may be encapsulated in a metal cage in order to provide enhanced rejection of the environmental parasitic electric and/or magnetic fields. A double boot strapping detector front-end configuration substantially eliminates the loading coming from both the gate-source and the gate-drain parasitic capacitances of the first sensor device of the detector that is connected to the quantum structure. In addition, differential detection aids in rejecting leakage, noise, and correlated interference coupling. Both dummy referenced differential detection as well as self-referenced differential detection may be employed in the detector. Moreover, correlated double sampling is used after preamplification in the detector in order to further reject noise and perturbations in the system.
