Phase diagram of the spin-1/2 Heisenberg alternating chain in a magnetic field
Wei-Xia Chen, Jie Ren, Wen-Long You +2
By using the infinite time-evolving block decimation, we study quantum fidelity and entanglement entropy in the spin-1/2 Heisenberg alternating chain under an external magnetic fie…
Quantum Parameter Estimation in the Unruh-DeWitt detector model
Xiang Hao, Yinzhong Wu
Relativistic effects on the precision of quantum metrology for particle detectors, such as two-level atoms are studied. The quantum Fisher information is used to estimate the phase…
Thermal Quantum Speed Limit for Classical-Driving Open Systems
Wenjiong Wu, Kai Yan, Xiang Hao
Quantum speed limit (QSL) time for open systems driven by classical fields is studied in the presence of thermal bosonic environments. The decoherence process is quantitatively des…
Expansion dynamics in a one-dimensional hard-core boson model with three-body interactions
Jie Ren, Yin-Zhong Wu, Xue-Fen Xu
Using the adaptive time-dependent density matrix renormalization group method, we numerically investigate the expansion dynamics of bosons in a one-dimensional hard-core boson mode…
Quantum discord and entanglement in Heisenberg XXZ spin chain after quenches
Jie Ren, Yin-Zhong Wu, Shi-Qun Zhu
Using the adaptive time-dependent density-matrix renormalization group method, the dynamics of entanglement and quantum discord of a one-dimensional spin-1/2 XXZ chain is studied w…
Implementing controlled-NOT gate based on free spin qubits with semiconductor quantum-dot array
Yin-Zhong Wu, Wei-Min Zhang
Based on electron spins in semiconductor quantum dots as qubits, a new quantum controlled-NOT(CNOT) gate is constructed in solid nanostructure without resorting to spin-spin intera…
