Analysis of multisource errors accompanying process execution and study the propagation effects corresponding multiprocess manufacturing are basic prerequisites for optimizing generation improving quality product. This paper proposes an analytical framework error in manufacturing, which completely covers source analysis, mathematical calculation accumulation, description effects, can provide be...

We propose a random circuit model to analyze the impact of noise on performance variational quantum circuits for classical optimization problems. Our accounts propagation arbitrary single qubit errors through circuit. find that even with small rate, quality obtained optima is low average and single-qubit error rate $1 / nD$, where $n$ number qubits $D$ depth, needed possibility advantage. estim...
