Episode 2 is a bit weird. It seems it implies the world which we live in, is perceived via our senses and brain right? But our body and other physical presences are actually just objects exist simultaneously in several infinite multiverse. Our consciousness, is attached to one of such body and perceive the reality from a single universe. The genius built several quantum computers, which can magically "tune" the consciousness to perceive a different universe which fits into the criteria given to the computers via remote. That's how a person can magically change reality just by giving out the criteria via oral instructions. When reality changes, it just mean that person consciousness is now attached to a different universe.

Then why would 2 persons in the show know what have been changed instead of just a single person? Because as the genius explained, part of the criteria is that the other person in the new universe knows exactly what has been changed. Since multiverse is infinite, therefore such a universe always exist. End up the changed reality can be perceived by the person who has the remote, as well as the other person that is singled out to have prior knowledge of the reality of the previous universe.

As a common theme in Black Mirror, it is another story about consciousness and how it perceives reality. But this time involves quantum computers and some magical mean to jump from one reality to another.
