Tomography by Design: An Algebraic Approach to Low-Rank Quantum States 事件

Tomography by Design: An Algebraic Approach to Low-Rank Quantum States arXiv:2602.15202v2 Announce Type: replace-cross Abstract: We present an algebraic algorithm for quantum state tomography that leverages measurements of certain observables to estimate structured entries of the underlying density matrix. Under low-rank assumptions, the remaining entries can be obtained solely using standard numerical linear algebra operations. The proposed algebraic matrix completion framework applies to a br
