Algorithm for evaluating distance-based entanglement measures
Yixuan Hu, Ye-Chao Liu, Jiangwei Shang
Quantifying entanglement in quantum systems is an important yet challenging task due to its NP-hard nature. In this work, we propose an efficient algorithm for evaluating distance-…
Efficient verification of arbitrary entangled states with homogeneous local measurements
Ye-Chao Liu, Yinfei Li, Jiangwei Shang +1
Quantum state verification (QSV) is the task of relying on local measurements only to verify that a given quantum device does produce the desired target state. Up to now, certain t…
Operational detection of entanglement via quantum designs
Xin Yan, Ye-Chao Liu, Jiangwei Shang
From an operational point of view, we propose several new entanglement detection criteria using quantum designs. These criteria are constructed by considering the correlations defi…
Efficient verification of entangled continuous-variable quantum states with local measurements
Ye-Chao Liu, Jiangwei Shang, Xiangdong Zhang
Continuous-variable quantum states are of particular importance in various quantum information processing tasks including quantum communication and quantum sensing. However, a bott…
Universally Optimal Verification of Entangled States with Nondemolition Measurements
Ye-Chao Liu, Jiangwei Shang, Rui Han +1
The efficient and reliable characterization of quantum states plays a vital role in most, if not all, quantum information processing tasks. In this work, we present a universally o…
Efficient verification of quantum processes
Ye-Chao Liu, Jiangwei Shang, Xiao-Dong Yu +1
Quantum processes, such as quantum circuits, quantum memories, and quantum channels, are essential ingredients in almost all quantum information processing tasks. However, the char…
Efficient verification of Dicke states
Ye-Chao Liu, Xiao-Dong Yu, Jiangwei Shang +2
Among various multipartite entangled states, Dicke states stand out because their entanglement is maximally persistent and robust under particle losses. Although much attention has…
Coherence Depletion in Quantum Algorithms
Ye-Chao Liu, Jiangwei Shang, Xiangdong Zhang
Besides the superior efficiency compared to their classical counterparts, quantum algorithms known so far are basically task-dependent, and scarcely any common features are shared…
