%hash = map {  join( q{ }, $fname[$_], $lname[$_] ) => $state[$_]  } 0
+ .. $#fname;

Update: Though it's not necessarily better in this case, it is sometimes convenient to place the map inside the key brackets of a hash slice:

@hash{    map{ join q{ }, $fname[$_], $lname[$_] } 0 .. $#fname    }  
+=  @state;

List::MoreUtils might be fun... let's see.....:

use List::MoreUtils qw( zip pairwise );
# ...
%hash = zip    @{[  pairwise { join q( ), $a, $b } @fname, @lname  ]},
+    @state;

Maybe that's just ridiculous. ;)

I should mention that if you didn't have the requirement of joining @fname and @lname stringwise, and instead were dealing with just a single list of keys, and a single list of values, the hash slice technique would be an ideal solution:

@hash{@names} = @states;

It doesn't get more succinct than that.
