Deterministic transformations between unitary operations: Exponential advantage with adaptive quantum circuits and the power of indefinite causality
Marco Túlio Quintino, Daniel Ebler
This work analyses the performance of quantum circuits and general processes to transform uses of an arbitrary unitary operation into another unitary operation . When…
Unitary channel discrimination beyond group structures: Advantages of sequential and indefinite-causal-order strategies
Jessica Bavaresco, Mio Murao, Marco Túlio Quintino
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 g…
Simple and maximally robust processes with no classical common-cause or direct-cause explanation
Marcello Nery, Marco Túlio Quintino, Philippe Allard Guérin +2
Guided by the intuition of coherent superposition of causal relations, recent works presented quantum processes without classical common-cause and direct-cause explanation, that is…
