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…

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 …

Joint product numerical range and geometry of reduced density matrices
Jianxin Chen, Cheng Guo, Zhengfeng Ji +4
The reduced density matrices of a many-body quantum system form a convex set, whose three-dimensional projection is convex in . The boundary of ma…
