Any [[computational problem]] solvable by a classical computer is also solvable by a quantum computer.<ref>Nielsen, p. 29</ref> Intuitively, this is because it is believed that all physical phenomena, including the operation of classical computers, can be described using [[quantum mechanics]], which underlies the operation of quantum computers.

经典计算机可以解决的任何[[计算问题]]也可以由量子计算机解决。<ref>尼尔森，第29页，</ref>直觉上，这是因为人们相信，所有物理现象，包括经典计算机的操作，都可以用[[量子力学]来描述，这是量子计算机操作的基础。

Conversely, any problem solvable by a quantum computer is also solvable by a classical computer; or more formally, any quantum computer can be simulated by a [[Turing machine]]<!-- add mention about [[Quantum Virtual Machines]] which can simulate quantum computer on classical one -->. In other words, quantum computers provide no additional power over classical computers in terms of [[computability]]. This means that quantum computers cannot solve [[undecidable problem]]s like the [[halting problem]] and the existence of quantum computers does not disprove the [[Church–Turing thesis]].<ref>Nielsen, p. 126</ref>

相反，量子计算机可以解决的任何问题也可以用经典计算机来解决；或者更正式地说，任何量子计算机都可以用[[图灵机器]]<来模拟！--增加关于[[量子虚拟机]]的介绍，它可以在经典的量子计算机-->上模拟量子计算机。换句话说，量子计算机在[[可计算性]]方面没有比经典计算机更强大的能力。这意味着量子计算机不能解决[[不可判定的问题]]像[[停止问题]]一样，量子计算机的存在并不能反驳[[丘奇-图灵论点]]。

As of yet, quantum computers do not satisfy the [[Church–Turing thesis|strong Church thesis]]. While hypothetical machines have been realized, a universal quantum computer has yet to be physically constructed. The strong version of Church's thesis requires a physical computer, and therefore there is no quantum computer that yet satisfies the strong Church thesis.

到目前为止，量子计算机还不能满足[[丘奇-图灵理论|强大的教会理论]]。虽然假想的机器已经实现，但一个通用的量子计算机还没有被物理构造出来。丘奇理论的强版本需要一台物理计算机，因此还没有一台量子计算机能够满足强大的教会理论。
