Quantum systems have traditionally operated within highly controlled laboratory environments to minimize internal noise and maximize stability. However, when these systems are integrated into High Performance Computing (HPC) environments and setup for continuous operation, they encounter significantly higher levels of external noise and instability coupled with higher demands. This paper introduces a comprehensive framework to counter the challenges of maintaining the stability of operational quantum computers in such noisy HPC settings. We propose a novel system architecture that monitors and manages the environmental conditions of quantum computing systems using a broad set of sensors, enhancing their robustness and reliability. Our architecture is open and can be extended to other setups. It can serve as a blueprint for other sites as it spans quantum technologies and offers broad coverage. Ultimately, this data will be essential to facilitate advancements in machine learning to drive real-time error mitigation.

The coupled-dipole method is widely used to calculate the light-scattering matrix S from arbitrary particles. An important parameter in the model is the size of the dipolar subunits. Usually a size of approximately 1/10 to approximately 1/20 of the wavelength of the incident light is sufficient for accurate calculations. However, it was noted that accurate S-34 calculations require much smaller dipolar subunits. We show that this conclusion is too pessimistic, by examining the sensitivity of the S-34 elements on surface roughness of spherical particles. Furthermore we give an example of an accurate S-34 calculation with dipolar subunits as large as 1/10 of the wavelength.
