This article focuses on the development of scalable and qubit-efficient algorithms for computing power functions of random quantum states. Two algorithms, based on the Hadamard Test and Gate Set Tomography, are proposed. We provide a comparative analysis of their computational outcomes, accompanied by a meticulous evaluation of inherent errors in the Gate Set Tomography approach. The second algorithm exhibits a significant reduction in the utilization of two-qubit gates compared to the first.

1. IntroductionOrganic light-emitting diodes (OLEDs) hold great promise for applications in full-color display and solid-state lighting because of their striking advantages, such as high efficiency, fast response, and flexibility [1,2,3,4]. In order to pursue high efficiency, phosphor-doped OLEDs are a highly effective approach because of 100% internal quantum efficiency in principle via harnessing both singlet and triplet excitons [5,6,7].
