[email protected]) Abstract We discuss finite quantum theory (FQT) developed in our previous publica- tions and give a simple explanation that standard quantum theory is a special case of FQT in the formal limit p ! 1 where p is the characteristic of the ring or field used in FQT. Then we argue that FQT is a more natural basis for quantum computing than standard quantum theory. Keywords: finite mathematics, quantum theory, quantum computing 1 Motivation Classical computer science is based on discrete mathematics for obvious reasons. Any computer can operate only with a finite number of bits, a bit represents the minimum amount of information and the notions of one half of the bit, one third of the bit etc.
