No-communication theorem is a thing that exists and applies to quantum stuff.
Light-speed keeps to be a relevant limit on what can happen. If you have a superposition of state A+B and it resolves “superluminally” to one of those two, it can only span an area that A could have spread (at lightspeed) to or B could have spread (at lightspeed) to.
