HIGHLIGHTS
- who: Henry Yuen from the (UNIVERSITY) have published the article: An Improved Sample Complexity Lower Bound for (Fidelity) Quantum State Tomography, in the Journal: (JOURNAL)
- what: We proved a u2126(rd/ ) sample complexity lower bound for fidelity tomography for rank-r, dimension-d mixed states where 1 - is the fidelity of the resulting estimate.
- future: It is natural to conjecture that the optimal bound for fidelity tomography is n=u0398(rd/ ) however the authors leave obtaining a matching upper bound for future work.
