Shot Budget

A shot budget is the total number of times a quantum circuit is executed (sampled) for a given experiment or task. Because quantum measurement is probabilistic, circuits must be run many times to estimate probability distributions accurately. The shot budget determines how much precision you can achieve: doubling shots halves the statistical error (shot noise). Shot budgets are especially relevant in variational algorithms like VQE and QAOA, where each energy evaluation requires thousands of shots across multiple Pauli basis measurements. On cloud QPUs, shots directly translate to cost and queue time — so managing your shot budget is as important as optimizing circuit depth. HLQuantum lets you configure shots=N in hlq.run() and has utilities for estimating required shots for a target precision.
