Towards determining the presence of barren plateaus in some chemically inspired variational quantum algorithms
Rui Mao, Guojing Tian, Xiaoming Sun
In quantum chemistry, the variational quantum eigensolver (VQE) is a promising algorithm for molecular simulations on near-term quantum computers. However, VQEs using hardware-effi…

Towards Optimal Circuit Size for Sparse Quantum State Preparation
Rui Mao, Guojing Tian, Xiaoming Sun
Compared to general quantum states, the sparse states arise more frequently in the field of quantum computation. In this work, we consider the preparation for -qubit sparse quan…
