A hybrid quantum circuit consisting of a superconducting flux qubit coupled to both a spin ensemble and a transmission-line resonator
Ze-Liang Xiang, Xin-You Lu, Tie-Fu Li +2
We propose an experimentally realizable hybrid quantum circuit for achieving a strong coupling between a spin ensemble and a transmission-line resonator via a superconducting flux…
Implementing a topological quantum model using a cavity lattice
Ze-Liang Xiang, Ting Yu, Wenxian Zhang +2
Kitaev model has both Abelian and non-Abelian anyonic excitations. It can act as a starting point for topological quantum computation. However, this model Hamiltonian is difficult…
Confidence and Backaction in the Quantum Filter Equation
Wei Cui, Neill Lambert, Yukihiro Ota +4
We study the confidence and backaction of state reconstruction based on a continuous weak measurement and the quantum filter equation. As a physical example we use the traditional…
Hybrid quantum circuits: Superconducting circuits interacting with other quantum systems
Ze-Liang Xiang, Sahel Ashhab, J. Q. You +1
Hybrid quantum circuits combine two or more physical systems, with the goal of harnessing the advantages and strengths of the different systems in order to better explore new pheno…
Non-Markovian quantum state diffusion for an open quantum system in fermionic environments
Mi Chen, J. Q. You
Non-Markovian quantum state diffusion (NMQSD) provides a powerful approach to the dynamics of an open quantum system in bosonic environments. Here we develop an NMQSD method to stu…
Atomic physics and quantum optics using superconducting circuits
J. Q. You, Franco Nori
Superconducting circuits based on Josephson junctions exhibit macroscopic quantum coherence and can behave like artificial atoms. Recent technological advances have made it possibl…
