Faithful geometric measures for genuine tripartite entanglement
Xiaozhen Ge, Lijun Liu, Yong Wang +4
We present a faithful geometric picture for genuine tripartite entanglement of discrete, continuous, and hybrid quantum systems. We first find that the triangle relation $\mathcal{…
Joint Estimation of a Two-Phase Spin Rotation beyond Classical Limit
Jiahao Cao, Xinwei Li, Tianwei Mao +2
Quantum metrology employs entanglement to enhance measurement precision. The focus and progress so far have primarily centered on estimating a single parameter. In diverse applicat…
Efficient fault-tolerant implementations of non-Clifford gates with reconfigurable atom arrays
Yi-Fei Wang, Yixu Wang, Yu-An Chen +6
To achieve scalable universal quantum computing, we need to implement a universal set of logical gates fault-tolerantly, for which the main difficulty lies with non-Clifford gates.…
Entanglement generation via single-qubit rotations in a torn Hilbert space
Tao Zhang, Zhihao Chi, Jiazhong Hu
We propose an efficient yet simple protocol to generate arbitrary symmetric entangled states with only global single-qubit rotations in a torn Hilbert space. The system is based on…
Correlation-pattern-based Continuous-variable Entanglement Detection through Neural Networks
Xiaoting Gao, Mathieu Isoard, Fengxiao Sun +5
Entanglement in continuous-variable non-Gaussian states provides irreplaceable advantages in many quantum information tasks. However, the sheer amount of information in such states…
Assisted metrology and preparation of macroscopic superpositions with split spin-squeezed states
Jiajie Guo, Fengxiao Sun, Qiongyi He +1
We analyse the conditional states in which one part of a split spin-squeezed state is left, upon performing a collective spin measurement on the other part. For appropriate measure…

Xianjue Zhao, Peiyun Ge, Hongye Yu +3
With qubits encoded into atomic ground and Rydberg states and situated on the vertexes of a graph, the conditional quantum dynamics of Rydberg blockade, which inhibits simultaneous…
No Strings Attached: Boundaries and Defects in the Cubic Code
Cory T. Aitchison, Daniel Bulmash, Arpit Dua +2
Haah's cubic code is the prototypical type-II fracton topological order. It instantiates the no string-like operator property that underlies the favorable scaling of its code dista…
