It may be that we might not need to go so deep to effect the coincidental juxtapositioning of spatial co-ordinates within the framework of time and space. Notice I left out the fixed framework, because you're right of course.

When ALexander Graham Bell invented the telephone, when Marconi effected the first controlled transmission of electromagnetic waves across space, when electronic engineers design frequency modulation transmitters or even design simple amplitude modulation circuits for transistor radios they are none of them concerned with the physics of it at the quantum level. What happens at that level is the consequence of the practical application of theory, and reality cooperates.

Engineers in the physics community have apparently given up on the concept of electron sheets, intended to act as force fields, because they are inherently unstable and require unmanageable amounts of energy to make them stable. Photon entanglement presents its own problems, it's tough enough to manipulate a single tiny particle that exists only for the briefest of instants let alone an entire object at the macro scale using entanglement principles.

What is left is to define a plane two dimensional area of space, and modulate that specific area with the characteristics of a similar two-dimensional plane that exists in another place. Simply walking through it would theoretically put you in that other place. The theory behind the concept is sound. Research has determined that every particle in the universe has unique properties of spin, orientation, direction, position, etc. with respect to every other particle. These include the time relationship that they have with their environment. If we could detect and transmit this information we could modulate all those characteristics into the defined areas and effectively trade places with points in space.

Start small, but think big.
