What if, photons do interact?

The team believes that photon interactions could be manipulated in ways that make them an asset to quantum computers.
Until just a few years ago, scientists had never seen photons interact. In a new study, photons were observed binding in groups of three, accumulating mass, and slowing down.
Researchers observed groups of three photons not only interacting, but effectively combining to form a completely new type of photonic matter. This outcome essentially reveals a new form of light.

To make interacting photons, the team shone a weak laser through a cloud of cold rubidium atoms. Rather than emerging from this cloud separately, the photons within the laser merged bound in groups of three. This observation suggests a form of interaction and attraction — also known as entanglement.

If so, they say that interaction could be used in quantum computers.
It's interesting that when combined the new combo had mass.
That suggests to me that regular photons have mass too, but it's just so minimal as not to be measurable, or observable, by current technologies.
I have a hard time wrapping my head around massless particles.
