Exceptional Points in a Parallel Double-Quantum-Dot Josephson Junction Coupled to a Ferromagnetic Reservoir
Yiyan Wang, Ruixin Zhou, Bing Dong
We investigate exceptional points (EPs) in a parallel double-quantum-dot Josephson junction coupled to a dissipative reservoir. By integrating out the leads, we obtain a non-Hermit…
Heterogeneous entanglement between a trapped ion and a solid-state quantum memory
Chen-Xu Wang, Yi-Yang Wang, Tian-Xiang Zhu +11
Hybrid quantum networks offer a promising architecture for scalable quantum information processing and a future quantum internet, as they can combine the complementary strengths of…
Magnetic flux controlled current phase relationship in double Quantum Dot Josephson junction
Yiyan Wang, Cong Li, Bing Dong
In this work, we study a Josephson junction with parallel-connected quantum dots (QDs) threaded by a magnetic flux in the central region. We discretize the superconducting (SC) ele…
Quantum phase transition in a double quantum dot Josephson junction driven by electron-electron interactions
Cong Li, Yiyan Wang, Bing Dong
In this work, we employ a surrogate BCS model with discrete energy levels to investigate a hybrid system comprising two quantum dots (QD1 and QD2), where QD1 is tunnel-coupled to t…
