ABSTRACT Non‐Hermitian quantum systems exhibiting parity‐time () symmetry can yield real eigenvalues under specific parameter regimes, expanding traditional ideas of Hermitian operators in quantum mechanics. This concept has catalyzed the development of experimental platforms, particularly in electronics and optics, where pseudo‐Hermitian principles enable useful implementations providing insight into their behaviors. Among these, active LCR circuit dimers have emerged as powerful tools to test ‐symmetry breaking, mode coalescence, and nonreciprocal signal dynamics. This work presents a systematic design methodology for constructing circuit topologies that mimic quantum Hamiltonians (both Hermitian and non‐Hermitian) via a decomplexification framework. The proposed approach accommodates a range of and anti‐ configurations through a flexible coupled oscillator network, offering practical utility in signal processing, metamaterials, and coherent amplification devices.
