Optimal Error Exponents for Composite Sequential Quantum Hypothesis Testing
Jacob Paul Simpson, Efstratios Palias, Sharu Theresa Jose
We study the composite sequential quantum hypothesis testing (SQHT) problem, where the objective is to distinguish a null quantum state from a set of alternative quantum states. We…
