::I guess from the terms you mention, [[multilateration]] is closest (because quantum position verification uses the timing, not the angle (thus not [[triangulation]])), and usually has four or more verifiers (thus not [[trilateration]]). But it is not really [[multilateration]] either, because it locates via the response times, while multilateration uses the differences in arrival times of the signal (i.e., communication is unidirectional).
 
::I am not sure what you mean by "taking into account [[space-time]]". Do you mean that the curvature of space-time needs to be taken into account? That would only necessary for long distance position verification, I believe (otherwise the errors are very small and can be ignored). (But curved spacetime can be handled, see http://eprint.iacr.org/2014/118/20140216:194504. Disclaimer: own research.)
