Impossible to conjugate an unknown quantum state via a unitary evolution
Dafa Li
Abstract
The no-cloning theorem, the no-deleting theorem, the no-hiding theorem, the no-flip theorem, and the no-broadcasting play a crucial role in quantum mechanics and quantum information. In this paper, we propose the no-conjugating theorem which states that it is impossible to conjugate an unknown arbitrary quantum state via a universal physical device or linear/unitary operation.
