Joint Realizability Tradeoffs Bounded by Quantum Channel Incompatibility

Shintaro Minagawa, Ryo Takakura, Kensei Torii

Incompatible quantum channels cannot be jointly and exactly realized, meaning that any approximate joint realization inevitably entails a tradeoff in implementation accuracy. While…

Multivariate Rényi divergences characterise betting games with multiple lotteries

Andrés F. Ducuara, Erkka Haapasalo, Ryo Takakura

We provide an operational interpretation of the multivariate Rényi divergence in terms of economic-theoretic tasks based on betting, risk aversion, and multiple lotteries. We show…

Comparing quantum incompatibility of device sets from an operational perspective

Kensei Torii, Ryo Takakura, Ryotaro Imamura

To effectively utilize quantum incompatibility as a resource in quantum information processing, it is crucial to evaluate how incompatible a set of devices is. In this study, we pr…

Multi-object operational tasks for measurement incompatibility

Andrés F. Ducuara, Ryo Takakura, Fernando J. Hernandez +1

We introduce multi-object operational tasks for measurement incompatibility in the form of multi-object quantum subchannel discrimination and exclusion games with prior information…
