A duplication-free quantum neural network for universal approximation

  title={A duplication-free quantum neural network for universal approximation},
  author={Xiaokai Hou and Guanyu Zhou and Qing Li and Shan Jin and Xiaoting Wang},
The universality of a quantum neural network refers to its ability to approximate arbitrary functions and is a theoretical guarantee for its effectiveness. A non-universal neural network could fail in completing the machine learning task. One proposal for universality is to encode the quantum data into identical copies of a tensor product, but this will substantially increase the system size and the circuit complexity. To address this problem, we propose a simple design of a duplication-free…
