An entropy-based feedback rule, S = k * 2^H, is proposed to adapt the per-iteration shot count in VQAs, claiming about 50% shot savings over fixed-shot training while preserving final cost accuracy.
However, due to the pres- ence of noise in real quantum hardware, the number of shots is sometimes increased to ensure more reliable re- sults [37]
