My sense of self is tied to my moment to moment experience of organic doses of personal body chemistry, tossed with memory and the result of my personal influence on the interpretation of my environment that has effected the network of synapses and has created roadways for my personal thought processes ever since my birth. I think it's just too juicy and random for a computer replication.
But, suppose...
God willing, if there were some way to make an exact replica of myself... Imagine a replicator, I step in..two of me step out... At that moment I think we would have the same mental experience of qualia as you describe, Count Ib. There's a cartoon strip of Calvin and Hobbs portraying this situation
