In this paper, we put forward a fundamental question concerning feedback control of quantum systems: Is measurement-based feedback control still better than openloop control? In c...
We study the complexity of some computational problems on finite black-box rings whose elements are encoded as strings of a given length and the ring operations are performed by a ...
Abstract. It is well-known that no classical algorithm can solve exactly (i.e., in bounded time without error) the leader election problem in anonymous networks. This paper propose...
