Journal ArticleDOI
Excitation spectrum for an inhomogeneously dipole-field-coupled superconducting qubit chain
Hou Ian,Yu-xi Liu,Franco Nori +2 more
TL;DR: In this paper, the authors derived an exact diagonalization of the general N-qubit Hamiltonian and demonstrated how the l-dependent operators lead to a denser one-excitation spectrum and a probability redistribution of the eigenstates.
Journal ArticleDOI
End-to-End Quantum Machine Learning Implemented with Controlled Quantum Dynamics
TL;DR: The proposal transforms the machine learning task to the optimization of a quantum control system, which parameterize the learning model by experimentally tunable control variables, which enables automated feature selection by encoding the raw input data to quantum states through agent control variables.
Journal ArticleDOI
Engineering entangled microwave photon states through multiphoton interactions between two cavity fields and a superconducting qubit.
TL;DR: In this paper, a universal algorithm was proposed to produce arbitrary superpositions of two-mode photon states of microwave fields in two separated transmission line resonators, which are coupled to a superconducting qubit.
Journal ArticleDOI
Fast generation of multiparticle entangled state for flux qubits in a circle array of transmission line resonators with tunable coupling
TL;DR: In this article, a one-step approach to the fast generation of Greenberger-Horne-Zeilinger (GHZ) states in a circuit QED system with superconducting flux qubits was proposed.
Journal ArticleDOI
Nonreciprocal single-photon frequency converter via multiple semi-infinite coupled-resonator waveguides
TL;DR: In this article, a non-reciprocal single-photon frequency converter via multiple semi-infinite coupled-resonator waveguides (CRWs) was proposed.
