Quantum physics is surprising in many ways. One surprise is the threat to locality implied by Bell's Theorem. Another surprise is the capacity of quantum computation, which poses a threat to the complexity-theoretic Church-Turing thesis. In both cases, the surprise may be due to taking for granted a strict arrow-of-time assumption whose applicability may be limited to the classical domain. This possibility has been noted repeatedly in the context of Bell's Theorem. The argument concerning quantum computation is described here. Further development of models which violate this strong arrow-of-time assumption, replacing it by a weaker arrow which is yet to be identified, is called for.
量子物理学在很多方面都令人惊讶。一个令人惊讶之处在于贝尔定理对定域性构成的威胁。另一个令人惊讶之处是量子计算的能力，它对复杂性理论中的丘奇 - 图灵论题构成了威胁。在这两种情况下，这种惊讶可能是由于理所当然地接受了一个严格的时间箭头假设，而其适用性可能仅限于经典领域。这种可能性在贝尔定理的背景下已被多次提及。这里描述了关于量子计算的论点。需要进一步发展那些违反这种强时间箭头假设的模型，并用一个尚未确定的较弱箭头来取代它。
