Coherence phenomena arise from interference, or the addition, of wave-like amplitudes with fixed phase differences. Although coherence has been shown to yield transformative ways for improving function, advances have been confined to pristine matter and coherence was considered fragile. However, recent evidence of coherence in chemical and biological systems suggests that the phenomena are robust and can survive in the face of disorder and noise. Here we survey the state of recent discoveries, present viewpoints that suggest that coherence can be used in complex chemical systems, and discuss the role of coherence as a design element in realizing function.
相干现象源于干涉，即具有固定相位差的波状幅度的叠加。尽管已经证明相干现象为改善功能提供了变革性的方法，但进展仅限于原始物质，而且相干现象被认为是脆弱的。然而，最近在化学和生物系统中发现的相干现象的证据表明，这些现象是稳健的，可以在面对无序和噪声时存活。在这里，我们调查了最近的发现的状态，提出了一些观点，认为相干现象可以用于复杂的化学系统，并讨论了相干现象作为实现功能的设计元素的作用。
