(Phys.org) -- When two photons simultaneously enter two input ports of a beam splitter, their paths interfere destructively, which causes the photons to simultaneously exit the beam splitter through the same output port. Because this quantum interference effect changes the input into a different output, it could have applications in quantum information processing. But whereas the two photons are usually identical in experiments demonstrating this effect, a new study has demonstrated that quantum interference can also occur between two photons with different frequencies, giving researchers an additional degree of control.

Physicists take a perverse pleasure in playing with the strangeness of the quantum world. That's how they have managed to entangle minuscule objects such as photons
