Robustness-based bounds for approximate joint realizations of incompatible quantum channels
Shintaro Minagawa, Ryo Takakura, Kensei Torii
Several quantum channels may fail to admit an exact joint realization, a property known as incompatibility. Channel incompatibility unifies various quantum limitations, such as mea…
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…
