Quantum criticality in sub-Ohmic systems with three competing terms: beyond conventional spin-boson physics
Nengji Zhou, Yulong Shen, Zhe Sun
Quantum phase transitions (QPTs) in the spin-boson model with/without the rotating-wave approximation (RWA) are systematically investigated through variational calculations using a…
Experimental certification of ensembles of high-dimensional quantum states with independent quantum devices
Yong-Nan Sun, Meng-Yun Ma, Qi-Ping Su +3
When increasing the dimensionality of quantum systems, high-dimensional quantum state certification becomes important in quantum information science and technology. However, how to…
Advantage of quantum coherence in postselected metrology
Shao-Jie Xiong, Peng-Fei Wei, Huang-Qiu-Chen Wang +5
In conventional measurement, to reach the greatest accuracy of parameter estimation, all samples must be measured since each independent sample contains the same quantum Fisher inf…
Implementing quantum walks with a single qubit
Qi-Ping Su, Shi-Chao Wang, Yan Chi +5
Quantum walks have wide applications in quantum information, such as universal quantum computation, so it is important to explore properties of quantum walks thoroughly. We propose…
Coordinately Assisted Distillation of Quantum Coherence in Multipartite System
Huang-Qiu-Chen Wang, Qi Luo, Qi-Ping Su +4
We investigate the issue of assisted coherence distillation in the asymptotic limit (considering infinite copies of the resource states), by coordinately performing the identical l…
Unveiling quantum entanglement and correlation of sub-Ohmic and Ohmic baths for quantum phase transitions in dissipative systems
Xiaohui Qian, Zhe Sun, Nengji Zhou
By employing the spin-boson model in a dense limit of environmental modes, quantum entanglement and correlation of sub-Ohmic and Ohmic baths for dissipative quantum phase transitio…
