Dynamical speedup of a two-level system induced by coupling in the hierarchical environment
Kai Xu, Guo-Feng Zhang, Wu-Ming Liu
We investigate the dynamics of a two-level system in the presence of an overall environment composed of two layers. The first layer is just one single-mode cavity which decays to m…
Dephasing-insensitive quantum information storage and processing with superconducting qubits
Qiujiang Guo, Shi-Biao Zheng, Jianwen Wang +11
A central task towards building a practical quantum computer is to protect individual qubits from decoherence while retaining the ability to perform high-fidelity entangling gates…
A Unified and Strengthened Framework for the Uncertainty Relation
Xiao Zheng, Shao-Qiang Ma, Guo-Feng Zhang +2
We provide a unified and strengthened framework for the product form and the sum form variance-based uncertainty relations by constructing a unified uncertainty relation. In the un…
