Random dilation superchannel
Satoshi Yoshida, Ryotaro Niwa, Takeru Utsumi +2
We present a quantum circuit that implements the random dilation superchannel, transforming parallel queries of an unknown quantum channel into the same number of parallel queries…
Higher-order quantum computing with known input states
Vanessa Brzić, Satoshi Yoshida, Mio Murao +1
In higher-order quantum computing (HOQC), one typically considers the universal transformation of unknown quantum operations, treated as blackboxes. It is also implicitly assumed t…
Asymptotically optimal unitary estimation in by the analysis of graph Laplacian
Satoshi Yoshida, Hironobu Yoshida, Mio Murao
Unitary estimation is the task to estimate an unknown unitary operator with queries to the corresponding unitary operation, and its accuracy is evaluated b…
Quantum Advantage in Storage and Retrieval of Isometry Channels
Satoshi Yoshida, Jisho Miyazaki, Mio Murao
Storage and retrieval refer to the task of encoding an unknown quantum channel into a quantum state, known as the program state, such that the channel can later be retrieved. T…
