Nearly 30 years ago, two-photon interference was observed, marking the beginning of a new quantum era. Indeed, two-photon interference has no classical analogue, giving it a distinct advantage for a range of applications. The peculiarities of quantum physics may now be used to our advantage to outperform classical computations, securely communicate information, simulate highly complex physical systems and increase the sensitivity of precise measurements. This separation from classical to quantum physics has motivated physicists to study two-particle interference for both fermionic and bosonic quantum objects. So far, two-particle interference has been observed with massive particles, among others, such as electrons and atoms, in addition to plasmons, demonstrating the extent of this effect to larger and more complex quantum systems. A wide array of novel applications to this quantum effect is to be expected in the future. This review will thus cover the progress and applications of two-photon (two-particle) interference over the last three decades.
近30年前，人们观察到了双光子干涉，标志着一个新的量子时代的开始。事实上，双光子干涉没有经典的类似物，这使其在一系列应用中具有明显优势。量子物理学的特性现在可以为我们所用，以超越经典计算、安全地传递信息、模拟高度复杂的物理系统并提高精确测量的灵敏度。从经典物理到量子物理的这种转变促使物理学家研究费米子和玻色子量子物体的双粒子干涉。到目前为止，除了等离子体激元之外，已经在诸如电子和原子等大质量粒子中观察到了双粒子干涉，这证明了这种效应在更大、更复杂的量子系统中的范围。预计未来这种量子效应将有大量新颖的应用。因此，本综述将涵盖过去三十年中双光子（双粒子）干涉的进展和应用。
