On Efficiencies of Two TPCP maps Discrimination using Quantum Queries
Takehisa Iwakoshi (Mie Univ.)
Abstract (in Japanese) (See Japanese page) 
(in English) This study analyses the efficiency of three strategies to discriminate two Trace-Preserving Completely Positive maps (TPCP maps) by optimizing the input quantum query. The results are as follows. For N = 1, the efficiencies of all strategies degenerate. For N ≥ 2, the adaptive query strategy showed at least an exponential advantage compared to the parallel entangled query strategy by choosing the local operations as appropriate unitary operations. Therefore, this work is a natural generalization of the two unitary operator discrimination by an adaptive query in the past. The study also shows that the sharp discrimination using entanglement and a local TPCP map is impossible unless the target TPCP-maps are disjoint. However, the strategy would give an advantage over any other strategy thanks to the entanglement.
