摘要	Given a coin with unknown bias p is an element of[0,1], can we exactly simulate another coin with bias f (p)? The exact set of simulable functions has been well characterized 20 years ago. In this paper, we ask the quantum counterpart of this question: Given the quantum coin vertical bar p > = root p vertical bar 0 > + root 1 - p vertical bar 1 >, can we exactly simulate another quantum coin vertical bar f (p)> = root f (p)vertical bar 0 > + root 1 - f (p)vertical bar 1 >? We give the full characterization of simulable quantum state k(0)(p)vertical bar 0 > + k(1)(p)vertical bar 1 > from quantum coin vertical bar p > = root p vertical bar 0 > + root 1 - p vertical bar 1 >, and present an algorithm to transform it. Surprisingly, we show that simulable sets in the quantum-to-quantum case and classical-to-classical case have no inclusion relationship with each other.
