Researchers have developed a novel fixed-protocol amortized MPS estimator for quantum state tomography, significantly improving fidelity with fewer measurements. This approach, detailed in a recent arXiv paper, conditions on informative local Pauli measurements rather than random strings, leading to high-fidelity estimates around 0.95. The method also provides conformalized predictive uncertainty intervals, even for unmeasured observables, and demonstrates robust performance as system size and parameterization grow, with successful implementation on IBM hardware.
