Non-Hermitian scattering in SSH superconducting waveguides: exact Green-function reduction and dimerization-sensitive microwave functionalities
Jie Zhou, Xiao-Xue Zhang, Xi-Zheng Zhang
We formulate an exact Green-function theory for non-Hermitian single-microwave-photon scattering by finite superconducting circuit subsystems embedded in an SSH waveguide. The stru…
Single-photon scattering in a dissipative superconducting-qubit--SSH lattice hybrid
Xiao-Xue Zhang, Jie Zhou, Xi-Zheng Zhang
We study single-photon scattering in a Su--Schrieffer--Heeger (SSH) photonic lattice locally coupled to a superconducting qubit with tunable loss or gain. Working in the single-exc…
Robust and optimal control of open quantum systems
Zi-Jie Chen, Hongwei Huang, Lida Sun +9
Recent advancements in quantum technologies have highlighted the importance of mitigating system imperfections, including parameter uncertainties and decoherence effects, to improv…
Extending coherence time beyond break-even point using only drives and dissipation
Lida Sun, Yifang Xu, Yilong Zhou +11
Quantum error correction (QEC) aims to mitigate the loss of quantum information to the environment, which is a critical requirement for practical quantum computing. Existing QEC im…
Experimental demonstration of entanglement pumping with bosonic logical qubits
Jie Zhou, Chuanlong Ma, Yifang Xu +9
Entanglement is crucial for quantum networks and computation, yet maintaining high-fidelity entangled quantum states is hindered by decoherence and resource-intensive purification…
Engineering the Nonlinearity of Bosonic Modes with a Multi-loop SQUID
Ziyue Hua, Yifang Xu, Weiting Wang +8
Engineering high-order nonlinearities while suppressing lower-order terms is crucial for quantum error correction and state control in bosonic systems, yet it remains an outstandin…
