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…
A Quantum Key Distribution Protocol with Selecting Announced States, Robust against Photon Number Splitting Attacks
Eguchi Makoto, Hagiwara Manabu, Hideki Imai
We propose a new class of quantum key distribution protocol, that ended up to be robust against photon number splitting attacks in the weak laser pulse implementations. This protoc…
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…
