Quantum Search of Spatial Regions
... (1) One could argue that to maintain a ‘quantum database’ of size n requires n computing elements ([32], though see also [24]). So why not just exploit those elements to search the database in parallel? Then it becomes trivial to show that the search time is limited only by the radius of the databas ...

As a further option, the excitation may be split into two parts, each propagating to one end of the chain. This results in entangling three distant parties rather than two.
