Unitary channel discrimination beyond group structures: Advantages of sequential and indefinite-causal-order strategies
For minimum-error channel discrimination tasks that involve only unitary channels, we show that sequential strategies may outperform the parallel ones. Additionally, we show that general strategies that involve indefinite causal order are also advantageous for this task. However, for the task of dis...
