Landauer's princple for Fermionic field in one dimensional bag
Yu-Song Cao, YanXia Liu, Rong Zhang
We study the Landauer's principle of an Unruh-DeWitt detector linearly coupled to Dirac field in dimensional cavity. When the initial state of the field is vacuum, we obtai…
Quantum Quench dynamics in XY spin chain with ferromagnetic and antiferromagnetic interactions
Zhe Wang, Pan-Pan Fang, Yu-Liang Xu +4
In this manuscript we investigate the one-dimensional anisotropic XY model with ferromagnetic and antiferromagnetic interactions, which gives more interesting phase diagrams and dy…
Dynamics of entanglement in the one-dimensional anisotropic XXZ model
Han Zhang, Yu-Liang Xu, Rong-Tao Zhang +4
The dynamics of entanglement in the one-dimensional spin-1/2 anisotropic XXZ model is studied using the quantum renormalization-group method. We obtain the analytical expression of…
Localized State in a Two-Dimensional Quantum Walk on a Disordered Lattice
Peng Xue, Rong Zhang, Zhihao Bian +3
We realize a pair of simultaneous ten-step one-dimensional quantum walks with two walkers sharing coins, which we prove is analogous to the ten-step two-dimensional quantum walk wi…
Experimental quantum-walk revival with a time-dependent coin
Peng Xue, Rong Zhang, Hao Qin +4
We demonstrate a quantum walk with time-dependent coin bias. With this technique we realize an experimental single-photon one-dimensional quantum walk with a linearly-ramped time-d…
Realization of single-qubit positive operator-valued measurement via a one-dimensional photonic quantum walk
Zhihao Bian, Jian Li, Hao Qin +4
We perform generalized measurements of a qubit by realizing the qubit as a coin in a photonic quantum walk and subjecting the walker to projective measurements. Our experimental te…
Experimental realization of a generalized measuring device via a one-dimensional photonic quantum walk
Zhihao Bian, Rong Zhang, Hao Qin +3
We demonstrate an implementation of unambiguous state discrimination of two equally probable single-qubit states via a one-dimensional photonic quantum walk experimentally. Further…
Realization of a quantum walk in phase space using resonator-assisted double quantum dots
Zhihao Bian, Hao Qin, Xiang Zhan +2
We implement a quantum walk in phase space with a new mechanism based on the superconducting resonator-assisted double quantum dots. By analyzing the hybrid system, we obtain the n…
A one-dimensional quantum walk with multiple-rotation on the coin
Peng Xue, Rong Zhang, Hao Qin +3
We introduce and analyze a one-dimensional quantum walk with two time-independent rotations on the coin. We study the influence on the property of quantum walk due to the second ro…
