Lower bounds on the error probability of multiple quantum channel discrimination by the Bures angle and the trace distance
Ryo Ito, Ryuhei Mori
Quantum channel discrimination is a fundamental problem in quantum information science. In this study, we consider general quantum channel discrimination problems, and derive the l…

Quantum speedups for dynamic programming on -dimensional lattice graphs
Adam Glos, Martins Kokainis, Ryuhei Mori +1
Motivated by the quantum speedup for dynamic programming on the Boolean hypercube by Ambainis et al. (2019), we investigate which graphs admit a similar quantum advantage. In this…

Quantum supremacy and hardness of estimating output probabilities of quantum circuits
Yasuhiro Kondo, Ryuhei Mori, Ramis Movassagh
Motivated by the recent experimental demonstrations of quantum supremacy, proving the hardness of the output of random quantum circuits is an imperative near term goal. We prove un…
