Strength of interaction for information distribution
Takayuki Miyadera, Hideki Imai
Let us consider two quantum systems: system A and system B. Suppose that a classical information is encoded to quantum states of the system A and we distribute this information to…
Wigner-Araki-Yanase theorem on Distinguishability
Takayuki Miyadera, Hideki Imai
The presence of an additive conserved quantity imposes a limitation on the measurement process. According to the Wigner-Araki-Yanase theorem, the perfect repeatability and the dist…
Information-Disturbance Theorem for Mutually Unbiased Observables
Takayuki Miyadera, Hideki Imai
We derive a novel version of information-disturbance theorems for mutually unbiased observables. We show that the information gain by Eve inevitably makes the outcomes by Bob in th…
Entangled Markov Chains generated by Symmetric Channels
Takayuki Miyadera
A notion of entangled Markov chain was introduced by Accardi and Fidaleo in the context of quantum random walk. They proved that, in the finite dimensional case, the corresponding…
