Unitary-process discrimination with error margin
T. Hashimoto, A. Hayashi, M. Hayashi +1
We investigate a discrimination scheme between unitary processes. By introducing a margin for the probability of erroneous guess, this scheme interpolates the two standard discrimi…
Updating Quantum Cryptography Report ver. 1
Donna Dodson, Mikio Fujiwara, Philippe Grangier +24
Quantum cryptographic technology (QCT) is expected to be a fundamental technology for realizing long-term information security even against as-yet-unknown future technologies. More…
The geometric measure of entanglement for a symmetric pure state with positive amplitudes
Masahito Hayashi, Damian Markham, Mio Murao +2
In this paper for a class of symmetric multiparty pure states we consider a conjecture related to the geometric measure of entanglement: 'for a symmetric pure state, the closest pr…
Capacity with energy constraint in coherent state channel
Masahito Hayashi
We consider two kind of energy constraints when the output state is a coherent state. One is a constraint on the total energy during a fixed period; the other is a constraint on th…
