One-Shot Yield-Cost Relations in General Quantum Resource Theories
Ryuji Takagi, Bartosz Regula, Mark M. Wilde
Although it is well known that the amount of resources that can be asymptotically distilled from a quantum state or channel does not exceed the resource cost needed to produce it,…
Fundamental limits of quantum error mitigation
Ryuji Takagi, Suguru Endo, Shintaro Minagawa +1
The inevitable accumulation of errors in near-future quantum devices represents a key obstacle in delivering practical quantum advantages, motivating the development of various qua…
Correlation in Catalysts Enables Arbitrary Manipulation of Quantum Coherence
Ryuji Takagi, Naoto Shiraishi
Quantum resource manipulation may include an ancillary state called a catalyst, which aids the transformation while restoring its original form at the end, and characterizing the e…
Enhancing quantum models of stochastic processes with error mitigation
Matthew Ho, Ryuji Takagi, Mile Gu
Error mitigation has been one of the recently sought after methods to reduce the effects of noise when computation is performed on a noisy near-term quantum computer. Interest in s…
Operational applications of the diamond norm and related measures in quantifying the non-physicality of quantum maps
Bartosz Regula, Ryuji Takagi, Mile Gu
Although quantum channels underlie the dynamics of quantum states, maps which are not physical channels -- that is, not completely positive -- can often be encountered in settings…
