I. Introduction
Noisy intermediate-scale quantum (NISQ) machines have been proved their quantum supremacy [1]. Benefiting from the superposition and entanglement of quantum bit (qubit), quantum computers demonstrate huge advantages over classical computers in some specific applications, like Shor's integer factorization [2], Grover's database search [3], and quantum neural networks (QNNs) [4], [5]. Because of the immaturity and huge overhead of existing physical quantum processors, simulation on classical computers becomes crucial for better understanding quantum behaviors. Among different types of quantum simulators [6], full-state simulation [7] becomes important, because it allows deeper and larger quantum circuit simulation. It updates the state-vector in each time step.
