چکیده انگلیسی:
Noisy intermediate-scale quantum algorithms, which run on noisy quantum computers, should
be carefully designed to boost the output state fidelity. While several compilation approaches have been
proposed to minimize circuit errors, they often omit the detailed circuit structure information that does
not affect the circuit depth or the gate count. In the presence of spatial variation in the error rate of the
quantum gates, adjusting the circuit structure can play a major role in mitigating errors. In this article, we
exploit the freedom of gate reordering based on the commutation rules to show the impact of gate error
propagation paths on the output state fidelity of the quantum circuit, propose advanced predictive techniques
to project the success rate of the circuit, and develop a new compilation phase postquantum circuit mapping
to improve its reliability. Our proposed approaches have been validated using a variety of quantum circuits
with different success metrics, which are executed on IBM quantum computers. Our results show that
rescheduling quantum gates based on their error propagation paths can significantly improve the fidelity
of the quantum circuit in the presence of variable gate error rates.
