Perturbational Decomposition Analysis for Quantum Ising Model with Weak Transverse Fields
Youning Li, Junfeng Huang, Chao Zhang +1
This work presented a perturbational decomposition method for simulating quantum evolution under the one-dimensional Ising model with both longitudinal and transverse fields. By tr…
Tapping into Permutation Symmetry for Improved Detection of k-Symmetric Extensions
Youning Li, Chao Zhang, Shi-Yao Hou +3
Symmetric extensions are essential in quantum mechanics, providing a lens to investigate the correlations of entangled quantum systems and to address challenges like the quantum ma…
Detecting Entanglement by Pure Bosonic Extension
Xuanran Zhu, Chao Zhang, Chenfeng Cao +3
In the realm of quantum information theory, the detection and quantification of quantum entanglement stand as paramount tasks. The relative entropy of entanglement (REE) serves as…
Maximum entropy methods for quantum state compatibility problems
Shi-Yao Hou, Zipeng Wu, Jinfeng Zeng +4
Inferring a quantum system from incomplete information is a common problem in many aspects of quantum information science and applications, where the principle of maximum entropy (…
Symmetric vs. bosonic extension for bipartite states
Youning Li, Shilin Huang, Dong Ruan +1
A bipartite state has a -symmetric extension if there exists a -partite state with marginals . The -symmetri…
Quantum Spacetime on a Quantum Simulator
Keren Li, Youning Li, Muxin Han +8
We experimentally simulate the spin networks -- a fundamental description of quantum spacetime at the Planck level. We achieve this by simulating quantum tetrahedra and their inter…
Quantum State Tomography for Generic Pure States
Shilin Huang, Jianxin Chen, Youning Li +1
We show that a generic -qudit pure quantum state is uniquely determined by only of its -particle reduced density matrices. Therefore we give a met…
Random Invariant Tensors
Youning Li, Muxin Han, Dong Ruan +1
Invariant tensors are states in the (local) SU(2) tensor product representation but invariant under global SU(2) action. They are of importance in the study of loop quantum gravity…
Local density matrices of many-body states in the constant weight subspaces
Jianxin Chen, Muxin Han, Youning Li +2
Let be the spin- Hilbert space with -dimensional single particle space. We fix an orthonormal basis for each …
Invariant Perfect Tensors
Youning Li, Muxin Han, Markus Grassl +1
Invariant tensors are states in the SU(2) tensor product representation that are invariant under the SU(2) action. They play an important role in the study of loop quantum gravity.…
Aharon-Vaidman quantum game with a Young-type photonic qutrit
Piotr Kolenderski, Urbasi Sinha, Li Youning +5
The Aharon-Vaidman (AV) game exemplifies the advantage of using simple quantum systems to outperform classical strategies. We present an experimental test of this advantage by usin…
