Rank and Range Criteria for Mixed-State Determination from Local Marginals
Xinyu Qiu, Minglong Qin, Caohan Cheng +2
Determining whether a mixed quantum state is uniquely determined among all states by its k-body marginals (k-UDA) is a fundamental problem in quantum system certification. We devel…
Mixed States Uniquely Determined by Marginals and Additivity
Xinyu Qiu, Lin Chen, Genwei Li +1
Identifying whether a mixed quantum state is uniquely determined among all states (UDA) by its local marginals is a basic problem in quantum information theory. We establish necess…
Machine Learning Framework for Efficient Prediction of Quantum Wasserstein Distance
Changchun Feng, Xinyu Qiu, Laifa Tao +1
The quantum Wasserstein distance (W-distance) is a fundamental metric for quantifying the distinguishability of quantum operations, with critical applications in quantum error corr…
Multipartite entangling power by von Neumann entropy
Xinyu Qiu, Zhiwei Song, Lin Chen
Quantifying the entanglement generation of a multipartite unitary operation is a key problem in quantum information processing. We introduce the definition of multipartite entangli…
Device-independent quantum state discrimination
Xinyu Qiu, Lin Chen
Quantum state discrimination depicts the general progress of extracting classical information from quantum systems. We show that quantum state discrimination can be realized in a d…
Quantum Wasserstein distance between unitary operations
Xinyu Qiu, Lin Chen
Quantifying the effect of noise on unitary operations is an essential task in quantum information processing. We propose the quantum Wasserstein distance between unitary operations…
Controlled remote implementation of operations via graph states
Xinyu Qiu, Lin Chen
We propose protocols for controlled remote implementation of operations with convincing control power. Sharing a -partite graph state, participants collaborate to prep…
Quantum cost of dense coding and teleportation
Xinyu Qiu, Lin Chen
The quantum cost is a key ingredient to evaluate the quality of quantum protocols from a practical viewpoint. We show that the quantum cost of d-dimensional dense coding protocol i…
Some special complex Hadamard matrices of order six
Mengfan Liang, Lin Chen, Fengyue Long +1
The complete classification of complex Hadamard matrices (CHMs) is a long-standing open problem. In this paper we investigate a series of CHMs, such as the CHMs contain…
