Quantum phase transition in the one-dimensional Dicke-Hubbard model with coupled qubits
Shu He, Li-Wei Duan, Yan-Zhi Wang +2
We study the ground state phase diagram of a one-dimensional two qubits Dicke-Hubbard model with XY qubit-qubit interaction. We use a numerical method combing the cluster mean-fiel…
Tuning nonequilibrium heat current and two-photon statistics via composite qubit-resonator interaction
Zhe-Huan Chen, Han-Xin Che, Zhe-Kai Chen +2
Quantum thermal transport and two-photon statistics serve as two representative nonequilibrium features in circuit quantum electrodynamics systems. Here, we investigate quantum hea…
Cycle Flux Ranking of Network Analysis in Quantum Thermal Device
Luqin Wang, Zi Wang, Chen Wang +1
Manipulating quantum thermal transport relies on uncovering the principle working cycles of quantum devices. Here, we apply the cycle flux ranking of network analysis to nonequilib…
Nonequilibrium thermal transport and photon squeezing in a quadratic qubit-resonator system
Chen Wang, Hua Chen, Jie-Qiao Liao
We investigate steady-state thermal transport and photon statistics in a nonequilibrium hybrid quantum system, in which a qubit is longitudinally and quadratically coupled to an op…
Geometric Heat Pump: Controlling Thermal Transport with Time-dependent Modulations
Zi Wang, Luqin Wang, Jiangzhi Chen +2
The second law of thermodynamics dictates that heat simultaneously flows from the hot to cold bath on average. To go beyond this picture, a range of works in the past decade show t…
Quantum phase transition of light in the dissipative Rabi-Hubbard lattice: A dressed-master-equation perspective
Tian Ye, Chen Wang, Qing-Hu Chen
In this work, we investigate the quantum phase transition of light in the dissipative Rabi-Hubbard lattice under the framework of the mean-field theory and quantum dressed master e…
A low-loss ferrite circulator as a tunable chiral quantum system
Ying-Ying Wang, Sean van Geldern, Thomas Connolly +5
Ferrite microwave circulators allow one to control the directional flow of microwave signals and noise, and thus play a crucial role in present-day superconducting quantum technolo…
A practical guide for building superconducting quantum devices
Yvonne Y. Gao, M. Adriaan Rol, Steven Touzard +1
Quantum computing offers a powerful new paradigm of information processing that has the potential to transform a wide range of industries. In the pursuit of the tantalizing promise…
Arbitrary controlled-phase gate on fluxonium qubits using differential ac-Stark shifts
Haonan Xiong, Quentin Ficheux, Aaron Somoroff +7
Large scale quantum computing motivates the invention of two-qubit gate schemes that not only maximize the gate fidelity but also draw minimal resources. In the case of superconduc…
