0000 The present disclosure introduces a differentiable framework for modeling quantum shot noise in state vector simulations used for training parameterized quantum circuits. Conventional approaches rely on multinomial sampling of measurement outcomes, which is inherently discrete and non-differentiable, blocking gradient-based optimization. To address this, the present disclosure replaces multinomial sampling with a continuous approximation using a multivariate Gaussian distribution that captures the statistical properties of shot noise. By applying a reparameterization technique, stochastic noise is expressed as a deterministic function of circuit parameters and auxiliary random variables, enabling gradients to propagate through the noise model. The method integrates noise directly into the quantum state vector, followed by normalization to maintain physical validity. This approach preserves differentiability while incorporating realistic noise effects, allowing efficient end-to-end training using standard optimization methods. The result is a scalable, noise-aware simulation framework that improves the fidelity and practicality of quantum machine learning development.

Techniques for tracking and maintaining queues used for executing pending quantum objects using respective quantum processing units (QPUs) are disclosed. An amount of time to execute a given quantum object depends on many factors, and a non-deterministic nature of quantum computing resources is such that, while knowing an expected wait time in a queue for access to a given QPU is useful, it is difficult to reliably determine.
