I was reading a pdf that mentioned a quantum-controlled beam splitter and wondered whether a quantum-controlled mirror exists. In the beam-splitter case, the beam splitter could either be present or absent, such that path information of photons was either preserved or not. It was controlled with a quantum event so that it's presence or absence was in a state of superposition.
For a mirror, could it be controlled by a quantum event such that it was in a superposition state of being reflective and transparent? If so, a beam could pass through it, be reflected back together, and form interference. It seems like isolation would be critical to keep the state from collapsing.
