Noise is perhaps the single most defining characteristic of current quantum computing and the NISQ era. NISQ algorithms are often hybrid in nature, dividing the computational load between both quantum and conventional hardware. In our case, the orbitals 𝜙 12 (𝑟) and 𝜙 37 (𝑟) of Eq. ( ) are precisely known functions represented on a conventional computer and assumed errorless. The quantum computer, in turn, stores the orbital occupations and phase. It is in the quantum computer where noise enters as uncertainty and measurement errors. As our interest lies with the 1-RDM, we will focus on the specific effects of noise on the elements 𝐷 13 .
