论文摘要
著名的Hong-Ou-Mandel效应是两粒子量子干扰的范式。如保利原理的规定，它的根源在相同的量子颗粒的对称性中。在两个输出端口的巧合中，都无法检测到横梁分离器上的两个相同的玻色子，这是在许多带有光甚至物质的实验中所证实的。在这里，我们确定部分时间逆转会将Beamsplitter线性耦合转换为放大。我们从这种二元性中推断出存在于量子放大器（增益2）中的未使用的两玻色子干涉效应，并确定基本机制是及时的不可区分性。这种基本机制对于任何骨bogoliubov转化都是通用的，因此我们预计对量子物理学有广泛的影响。
The celebrated Hong-Ou-Mandel effect is the paradigm of two-particle quantum interference. It has its roots in the symmetry of identical quantum particles, as dictated by the Pauli principle. Two identical bosons impinging on a beam splitter (of transmittance 1/2) cannot be detected in coincidence at both output ports, as confirmed in numerous experiments with light or even matter. Here, we establish that partial time reversal transforms the beamsplitter linear coupling into amplification. We infer from this duality the existence of an unsuspected two-boson interferometric effect in a quantum amplifier (of gain 2) and identify the underlying mechanism as timelike indistinguishability. This fundamental mechanism is generic to any bosonic Bogoliubov transformation, so we anticipate wide implications in quantum physics.
