Lets talk physics on a quantum level for a moment,
It is a fact that electrons that inhabit the sphere of atoms can disappear and reappear from existence..seemingly at random. When scientists can control that..were laughing.
There are many applications. They never thought that we could change the building blocks of DNA..and control living cells...but we have and its common practice now.
Working on things at a quantum level is difficult yes, but these things are now a possibility, we are infact closer than you think to doing some remarkable things.
