Bounds for nonadiabatic transitions
Takuya Hatomura, Go Kato
We discuss bounds for nonadiabatic transitions from the viewpoints of the adiabatic perturbation theory and the quantum speed limit. We show that the amount of nonadiabatic transit…
Single-Shot Secure Quantum Network Coding for General Multiple Unicast Network with Free One-Way Public Communication
Go Kato, Masaki Owari, Masahito Hayashi
It is natural in a quantum network system that multiple users intend to send their quantum message to their respective receivers, which is called a multiple unicast quantum network…
Perfect discrimination of non-orthogonal quantum states with posterior classical partial information
Seiseki Akibue, Go Kato, Naoki Marumo
The indistinguishability of non-orthogonal pure states lies at the heart of quantum information processing. Although the indistinguishability reflects the impossibility of measurin…
Linear programs for entanglement and key distribution in the quantum internet
Stefan Bäuml, Koji Azuma, Go Kato +1
Quantum networks will allow to implement communication tasks beyond the reach of their classical counterparts. A pressing and necessary issue for the design of quantum network prot…
Quantum key distribution with setting-choice-independently correlated light sources
Akihiro Mizutani, Go Kato, Koji Azuma +6
Despite the enormous theoretical and experimental progress made so far in quantum key distribution (QKD), the security of most existing QKD implementations is not rigorously establ…
Algebra and Hilbert space structures induced by quantum probes
Go Kato, Masaki Owari, Koji Maruyama
In the general setting of quantum controls, it is unrealistic to control all of the degrees of freedom of a quantum system. We consider a scenario where our direct access is restri…
