Not too much. It might go unstable and break- especially with the 'weird' interference in the system- or something like that. I'd suggest that the only thing that's really stable and available would be quantum entanglement communicators, which would probably be back on the starships to instantly talk to home. You might have a type of pack or something that has one, though. I daresay that it'd probably be a piece of equipment worth trillions, and would likely be very... unpleasant to break. Experimental items, not so much.

So yeah, maybe a couple quantum mechanic devices, but not more than two or three total.
