The Optimal Rate Function in Covariant Quantum State Tomography
Arick Grootveld, Alexander Maloney, Jason Pollack +1
The problem of quantum tomography is to estimate an unknown quantum state from a measurement of copies of . One can ask which tomography protocol, i.e.\ which choice o…
GSC-QEMit: A Telemetry-Driven Hierarchical Forecast-and-Bandit Framework for Adaptive Quantum Error Mitigation
Steven Szachara, Sheeraja Rajakrishnan, Dylan Jay Van Allen +3
Quantum error mitigation (QEM) is essential for extracting reliable results from near-term quantum devices, yet practical deployments must balance mitigation strength against runti…
Asymptotically Optimal Quantum Universal Quickest Change Detection
Arick Grootveld, Haodong Yang, Nandan Sriranga +3
This paper investigates the quickest change detection of quantum states in a universal setting: specifically, where the post-change quantum state is not known a priori. We establis…
Towards Quantum Universal Hypothesis Testing
Arick Grootveld, Haodong Yang, Biao Chen +2
Hoeffding's formulation and solution to the universal hypothesis testing (UHT) problem had a profound impact on many subsequent works dealing with asymmetric hypotheses. In this wo…
