tommychahir,
Of course this can be done without Quantum::Superpositions, but since this sounded like fun: 
#! /usr/bin/perl
use strict;
use warnings;
use Quantum::Superpositions;

my @array_1 = (1 .. 4);
my @array_2 = qw{1 2 2 3 3 3 4 4 4 4 5 6 7};

my @array_3 = eigenstates( any(@array_2) != all(@array_1) );
my @array_4 = Quantum::Superpositions::eigenstates( any(@array_2) != a
+ll(@array_1) );

print "Ordered:\n";
print "$_\n" for @array_3;
print "Hash:\n";
print "$_\n" for @array_4;

{
    no warnings 'redefine';
    *eigenstates = *main::eigenstates;
    sub eigenstates ($) {
        my @uniq;
        my %seen;
        for ( Quantum::Superpositions::collapse( $_[0] ) ) {
            push @uniq , $_ if ! $seen{$_};
            $seen{$_}++;
        }
        return @uniq;
    }
}
