Optimal Entanglement Certification from Moments of the Partial Transpose
Xiao-Dong Yu, Satoya Imai, Otfried Gühne
For the certification and benchmarking of medium-size quantum devices efficient methods to characterize entanglement are needed. In this context, it has been shown that locally ran…
Exploring the relationship between the faithfulness and entanglement of two qubits
Gabriele Riccardi, Daniel E. Jones, Xiao-Dong Yu +2
A conceptually simple and experimentally prevalent class of entanglement witnesses, known as fidelity witnesses, detect entanglement via a state's fidelity with a pure reference st…
Geometry of faithful entanglement
Otfried Gühne, Yuanyuan Mao, Xiao-Dong Yu
A typical concept in quantum state analysis is based on the idea that states in the vicinity of some pure entangled state share the same properties; implying that states with a hig…
A complete hierarchy for the pure state marginal problem in quantum mechanics
Xiao-Dong Yu, Timo Simnacher, Nikolai Wyderka +2
Clarifying the relation between the whole and its parts is crucial for many problems in science. In quantum mechanics, this question manifests itself in the quantum marginal proble…
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…
Topological Dynamical Decoupling
Jiang Zhang, Xiao-Dong Yu, Gui-Lu Long +1
We show that topological equivalence classes of circles in a two-dimensional square lattice can be used to design dynamical decoupling procedures to protect qubits attached on the…
