Quantum dot magnetic based computer

Quantum scientist have also shown that an array of Single electron Transistor - SETs create a form of neural network." SETs construct computers that use individual electrons to carry information. SET biggest problem is operating at room temperature. Quantum tunneling means the can "interact capacitively rather than by current flow throught the wires." "When their interactions result from the quantum tunneling of electrons, quantum dots can collectively behave as a form of quantum cellular automaton, QCA. QCA computers may show associative memory. If Decoherence can be avoid a qbit can form with a 0 or 1 or superposition state of both at the same time. 5 qbits could handle 32 states (2^n), simulateously; a conventional computer would handle 32 sets of 5 bits, or 160 bits in all. 64 bit encryption could be processed with one 64 qubit operation, whereas, a conventional computer requiring 2^64, 1.84 x10^19 operations or 292.5 years, 18 billion billion times more powerful than a 64 bit binary compute
