Depending on how this second beam splitter is configured, the photons are measured as either waves or particles. However, the study authors did a clever thing to their set-up and attempted to ...

Two-photon interference, also known as the Hong-Ou-Mandel effect, occurs when two identical photons enter a beam splitter from different input ports but exit together out of the same output port.

Diamond exchanges Here BS stands for beam splitter and SW stands for ideal switches. In the transmission channel, the photon is accessible to Eve. (Courtesy: Salih et al./Phys. Rev. Lett.) The second ...

Figure 1: The single-photon source. Figure 4: The probability that two photons that collide at the beam splitter leave in opposite directions, plotted as a function of interferometer delay offset ...

If, before impinging on the beam splitter, one photon is delayed in time with respect to the other by going through or being reflected by the sample, one can retrieve in real time the value of ...

But if a second (output) beam splitter is added, even after the photon has passed the first beam splitter, the photon will act like a wave and seemingly take both paths. Credit: M. Telfer.

The first beam splitter sends a photon at half strength along two paths. Mirrors on each path redirect to the second beam splitter producing wave-like interference. But a blocking detector on either ...

Simply put, if you apply a global phase change to one beam relative to another when incident on an ordinary beamsplitter, it will change the time of arrival of the photon.
