Measuring the degree of unitarity for any quantum process
Jing-Xin Cui, Z. D. Wang
Quantum processes can be divided into two categories: unitary and non-unitary ones. For a given quantum process, we can define a \textit{degree of the unitarity (DU)} of this proce…
Topological quantum memory interfacing atomic and superconducting qubits
Zheng-Yuan Xue, Zhang-qi Yin, Yan Chen +2
We propose a scheme to manipulate a topological spin qubit which is realized with cold atoms in a one-dimensional optical lattice. In particular, by introducing a quantum opto-elec…
Generalized joint density of states and its application to exploring the pairing symmetry of superconductors
Dan-Bo Zhang, Qiang Han, Z. D. Wang
We introduce a generalized joint density of states (GJDOS), which incorporates the coherent factor into the JDOS, to study quasiparticle interference (QPI) in superconductors. The…
Relativistic quantum effects of Dirac particles simulated by ultracold atoms
Dan-Wei Zhang, Zi-Dan Wang, Shi-Liang Zhu
Quantum simulation is a powerful tool to study a variety of problems in physics, ranging from high-energy physics to condensed-matter physics. In this article, we review the recent…
Simulation of the spin-boson model with superconducting phase qubit coupled to a transmission line
Long-Bao Yu, Ning-Hua Tong, Zheng-Yuan Xue +2
Based on the rapid experimental developments of circuit QED, we propose a feasible scheme to simulate a spin-boson model with the superconducting circuits, which can be used to det…
Entanglement charge of thermal states
Ming-Yong Ye, Xiu-Min Lin, Yan-Kui Bai +1
Entanglement charge is an operational measure to quantify nonlocalities in ensembles consisting of bipartite quantum states. Here we generalize this nonlocality measure to single b…
