Authorized quantum computation
Yu Tanaka, Mio Murao
We present authorized quantum computation, where only a user with a non-cloneable quantum authorization key can perform a unitary operation created by an authenticated programmer.…

Thermal robustness of multipartite entanglement of the 1-D spin 1/2 XY model
Yoshifumi Nakata, Damian Markham, Mio Murao
We study the robustness of multipartite entanglement of the ground state of the one-dimensional spin 1/2 XY model with a transverse magnetic field in the presence of thermal excita…

ε-convertibility of entangled states and extension of Schmidt rank in infinite-dimensional systems
Masaki Owari, Samuel L. Braunstein, Kae Nemoto +1
By introducing the concept of -convertibility, we extend Nielsen's and Vidal's theorems to the entanglement transformation of infinite-dimensional systems. Using an infinite-dim…
