This is about freezing light, mostly so it can be used as memory in photonic computing, which is one of the places we are going with the future of computing, that is, beyond circuits for electric information. The following two articles are just about the ubiquity of quantum mechanical manipulation in increasingly 'normal' circumstances.

Device can theoretically trap a light 'bit' for an infinite amount of time
Lannebère and Silveirinha showed that this strategy for confining light can be achieved by shining light on a spherical "meta-atom," so-named because it allows light to have only a specific quantized energy value (creating a light "bit"), similar to how an atom allows electrons to occupy only certain quantized energy levels.

Physicists mimic quantum entanglement with laser pointer to double data speeds

"While there's no 'spooky action at a distance,' it's amazing that quantum entanglement aspects can be mimicked by something that simple."
