A quantum-operator analysis of N-fold phase accumulation in coherence de Broglie wavelength interferometry
This research investigates a novel sensing technique using an antisymmetric coupling between Mach-Zehnder interferometers to achieve N-fold phase accumulation via the coherence de Broglie wavelength (CBW) mechanism. This method enables superresolution beyond classical limits by exploiting SU(2) symmetry in coupled MZIs, offering enhanced sensitivity without violating standard quantum resource scaling.
