Unified Framework for Quantum Resource Recycling via Instrument-Dependent Back-action
Zinuo Cai, Jianxin Song, Changliang Ren
Accurate characterization of measurement backaction is crucial for understanding the limits of reusing quantum correlations in sequential scenarios. Here, we develop a unified quan…
Efficient Identification the Inequivalence of Mutually Unbiased Bases via Finite Operators
Jianxin Song, Zhen-Peng Xu, Changliang Ren
The structural characterization of high-dimensional mutually unbiased bases (MUBs) by classifying MUBs subsets remains a major open problem. The existing methods not only fail to c…
Enhanced Nonreciprocal Quantum Battery Performance via Nonlinear Two-Photon Driving
Luxin Xu, Changliang Ren
Quantum batteries have attracted significant attention as efficient quantum energy storage devices.In this work, we propose a nonlinear two-photon driving quantum battery model fea…
Complementarity Reveals Entanglement Sharing in Sequential Quantum Measurements
Zinuo Cai, Changliang Ren
We investigate entanglement sharing in a two-qubit sequential measurement scenario using three complementary classical correlation metrics: mutual information (I), sum of condition…
Locality Implies Complex Numbers in Quantum Mechanics
Tianfeng Feng, Changliang Ren, Vlatko Vedral
We show that the presented real-number quantum theories, compatible with the independent source assumption, require the inclusion of a nonlocal map. This means that if the independ…
Quantum energy teleportation via random bi-partitioning in N-qubit systems
Zhirong Xun, Changliang Ren
This study investigates quantum energy teleportation (QET) using stochastic bi-partitioning in an body Hamiltonian system. In this protocol, project measurements are performed…
Sharing Quantum Steering via Standard Projective Measurements
Shufen Dong, Zinuo Cai, Chunfeng Wu +1
We propose a scheme for the sharing of quantum steering among three observers, Alice, Bob, and Charlie using standard projective measurements. We show that in the unilateral sequen…
Quantum Correlation Sharing: A Review On Recent Progress From Nonlocality To Other Non-Classical Correlations
Zinuo Cai, Changliang Ren, Tianfeng Feng +2
This review offers a comprehensive exploration and synthesis of recent advancements in the domain of quantum correlation sharing facilitated through sequential measurements. We ini…
Gaussian beam quantum radar protocol
Lorenzo Maccone, Yi Zheng, Changliang Ren
We present an entangled quantum radar protocol. It consists in scanning the sky with a thin Gaussian beam and measuring the travel time of the radiation reflected from the target,…
