Two Mode Photon Bunching Effect as Witness of Quantum Criticality in Circuit QED
Qing Ai, Ying-Dan Wang, Guilu Long +1
We suggest a scheme to probe critical phenomena at a quantum phase transition (QPT) using the quantum correlation of two photonic modes simultaneously coupled to a critical system.…
A Unified Quantum NOT Gate
Z. W. Yu, X. T. Ni, L. C. Kwek +1
We study the feasibility of implementing a quantum NOT gate (approximate) when the quantum state lies between two latitudes on the Bloch's sphere and present an analytical formula…
Nonlocal Entanglement Transformations Achievable by Separable Operations
Eric Chitambar, Runyao Duan
For manipulations of multipartite quantum systems, it was well known that all local operations assisted by classical communication (LOCC) constitute a proper subset of the class of…
Observable Topological Effects of Mobius Molecular Devices
Nan Zhao, H. Dong, Shuo Yang +1
We study the topological properties of quantum states for the spinless particle hopping in a Mobius ladder. This system can be regarded as a molecular device possibly engineered fr…
Ancilla-Assisted Discrimination of Quantum Gates
Jianxin Chen, Mingsheng Ying
The intrinsic idea of superdense coding is to find as many gates as possible such that they can be perfectly discriminated. In this paper, we consider a new scheme of discriminatio…
Protecting entanglement in superconducting qubits
Jing Zhang, Yu-xi Liu, Chun-Wen Li +2
When a two-qubit system is initially maximally-entangled, two independent decoherence channels, one per qubit, would greatly reduce the entanglement of the two-qubit system when it…
Brownian motion of a charged test particle driven by vacuum fluctuations near a dielectric half-space
Hongwei Yu, Xiangyun Fu, Puxun Wu
We study the Brownian motion of a charged test particle driven by quantum electromagnetic fluctuations in the vacuum region near a non-dispersive and non-absorbing dielectric half-…
Using squeezed field to preserve two-atom entanglement against spontaneous emissions
Jing Zhang, Re-Bing Wu, Chun-Wen Li +1
Tunable interaction between two atoms in a cavity is realized by interacting the two atoms with an extra controllable single-mode squeezed field. Such a controllable interaction ca…
Induced Entanglement Enhanced by Quantum Criticality
Qing Ai, Tao Shi, Guilu Long +1
Two qubit entanglement can be induced by a quantum data bus interacting with them. In this paper, with the quantum spin chain in the transverse field as an illustration of quantum…
Tripartite entanglement transformations and tensor rank
Eric Chitambar, Runyao Duan, Yaoyun Shi
Understanding the nature of multipartite entanglement is a central mission of quantum information theory. To this end, we investigate the question of tripartite entanglement conver…
Effective Hamiltonian approach to the Kerr nonlinearity in an optomechanical system
Z. R. Gong, H. Ian, Yu-xi Liu +2
Using the Born-Oppenheimer approximation, we derive an effective Hamiltonian for an optomechanical system that leads to a nonlinear Kerr effect in the system's vacuum. The oscillat…
Stochastic local operations and classical communication properties of the n-qubit symmetric Dicke states
D. Li, X. Li, H. Huang
Recently, several schemes for the experimental creation of Dicke states were described. In this paper, we show that all the -qubit symmetric Dicke states with ($2\leq l\leq…
Adiabatic Quantum Counting by Geometric Phase Estimation
Chi Zhang, Zhaohui Wei, Anargyros Papageorgiou
We design an adiabatic quantum algorithm for the counting problem, i.e., approximating the proportion, , of the marked items in a given database. As the quantum system undergoes…
Convergence properties of fixed-point search with general but equal phase shifts for any iterations
D. Li, X. Li, H. Huang
Grover presented the fixed-point search by replacing the selective inversions by selective phase shifts of . In this paper, we investigate the convergence behavior of the fixe…
General theory of decoy-state quantum cryptography with source errors
Xiang-Bin Wang, C. -Z. Peng, J. Zhang +2
The existing theory of decoy-state quantum cryptography assumes the exact control of each states from Alice's source. Such exact control is impossible in practice. We develop the t…
Quantum information with Gaussian states
X. -B. Wang, T. Hiroshima, A. Tomita +1
Quantum optical Gaussian states are a type of important robust quantum states which are manipulatable by the existing technologies. So far, most of the important quantum informatio…
