Skew informations from an operational view via resource theory of asymmetry
Ryuji Takagi
The Wigner-Yanase skew information was proposed to quantify the information contained in quantum states with respect to a conserved additive quantity, and it was later extended to…
State exchange with quantum side information
Yonghae Lee, Ryuji Takagi, Hayata Yamasaki +2
We consider a quantum communication task between two users Alice and Bob, in which Alice and Bob exchange their respective quantum information by means of local operations and clas…
Operational Advantage of Quantum Resources in Subchannel Discrimination
Ryuji Takagi, Bartosz Regula, Kaifeng Bu +2
One of the central problems in the study of quantum resource theories is to provide a given resource with an operational meaning, characterizing physical tasks in which the resourc…
Convex resource theory of non-Gaussianity
Ryuji Takagi, Quntao Zhuang
Continuous-variable systems realized in quantum optics play a major role in quantum information processing, and it is also one of the promising candidates for a scalable quantum co…
