Multicast quantum network coding as optimal symmetric universal cloning over a quantum network
Go Kato, Mio Murao, Masaki Owari
We study the problem of perfectly multicasting symmetric universal clones of unknown quantum states over quantum networks with free classical communication. We construct a protocol…

On algebraic analysis of Baker-Campbell-Hausdorff formula for Quantum Control and Quantum Speed Limit
Go Kato, Masaki Owari, Koji Maruyama
The necessary time required to control a many-body quantum system is a critically important issue for the future development of quantum technologies. However, it is generally quite…
