Virtual quantum neural networks
Benchi Zhao, Xuanqiang Zhao, Yinan Li +2
Quantum neural networks are a prominent model of quantum machine learning. Their training consists in the minimization of a given loss function over a parametrized family of quantu…
Causal-Class Hierarchies in Coherence-Constrained Channel Transformation
Lin Zhu, Benchi Zhao, Xuanqiang Zhao +3
Higher-order quantum transformations allow multiple channel uses to be combined through different causal architectures, from parallel and fixed-order sequential networks to general…
Variational quantum Hamiltonian engineering
Benchi Zhao, Keisuke Fujii
The Hamiltonian of a quantum system is represented in terms of operators corresponding to the kinetic and potential energies of the system. The expectation value of a Hamiltonian a…
Probabilistic channel simulation using coherence
Benchi Zhao, Kosuke Ito, Keisuke Fujii
Channel simulation using coherence, which refers to realizing a target channel with coherent states and free operations, is a fundamental problem in the quantum resource theory of…
