Doing a little more reading, some say it's not quite that simple.
1. Teleporter-It is said that we will have problems with anything over the atomic level, and no way we could transport a human.
2. Phaser Beam-If it is a "laser beam", then yes, we already have it. But you could be dodging it like you see on TV.
3. Holodeck. One problem is making a light projection solid. In ST. it says it uses a magnetic contament field to hold the photons in, but light is not affected by a magnetic field.
But that does not mean that we really won't figure out a way to do these things. It would be nice if we did, hopefully in my lifetime
