Model-Checking Linear-Time Properties of Quantum Systems
Mingsheng Ying, Yangjia Li, Nengkun Yu +1
We define a formal framework for reasoning about linear-time properties of quantum systems in which quantum automata are employed in the modeling of systems and certain closed subs…
Quantum-limited metrology in the presence of collisional dephasing
Y. C. Liu, G. R. Jin, L. You
Including collisional decoherence explicitly, phase sensitivity for estimating effective scattering strength of a two-component Bose-Einstein condensate is derived analytically…
Realization of Quantum State Privacy Amplification in a Nuclear Magnetic Resonance Quantum System
Liang Hao, Chuan Wang, Gui Lu Long
Quantum state privacy amplification (QSPA) is the quantum analogue of classical privacy amplification. If the state information of a series of single particle states has some leaka…
Testing nonclassicality in multimode fields: a unified derivation of classical inequalities
Adam Miranowicz, Monika Bartkowiak, Xiaoguang Wang +2
We consider a way to generate operational inequalities to test nonclassicality (or quantumness) of multimode (or multiparty) bosonic fields that unifies the derivation of many know…
Relationship between the n-tangle and the residual entanglement of even n qubits
X. Li, D. Li
We show that -tangle, the generalization of the 3-tangle to even qubits, is the square of the SLOCC polynomial invariant of degree 2. We find that the -tangle is not the…
Tensor Rank and Stochastic Entanglement Catalysis for Multipartite Pure States
Lin Chen, Eric Chitambar, Runyao Duan +2
The tensor rank (also known as generalized Schmidt rank) of multipartite pure states plays an important role in the study of entanglement classifications and transformations. We em…
