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…
Reduction Theorem for Secrecy over Linear Network Code for Active Attacks
Masahito Hayashi, Masaki Owari, Go Kato +1
We discuss the effect of sequential error injection on information leakage under a network code. We formulate a network code for the single transmission setting and the multiple tr…
Concentration inequality using unconfirmed knowledge
Go Kato
We give a concentration inequality based on the premise that random variables take values within a particular region. The concentration inequality guarantees that, for any sequence…
Second law of black hole thermodynamics
Koji Azuma, Go Kato
If simple entropy in the Bekenstein-Hawking area law for a Schwarzschild black hole is replaced with 'negative' quantum conditional entropy, which quantifies quantum entanglement,…
