A Missouri University of Science and Technology (Missouri S&T) researcher has patented a quantum processor capable of parallel computing that uses no transistors.
Missouri S&T professor C.H. Wu says the device could replace current electronic computing systems and provide quantum computing capabilities.
In total, the quantum processor replaces 24 transistors, using symbolic substitution rules instead of logic gates. "Quantum computing based on what I have developed is a viable alternative and I believe it is the only one of its kind available," says Wu.
He says if several of the new devices are wired together, it will form a cellular automaton capable of performing computation without the use of transistors as required in current computing systems, which will allow for much smaller processor chips and great increases in processing speed.
In addition, Wu says the processor is rule-based and can distinguish left and right in spatial relations on grids. "Even if some scientists had looked for cellular automata with the correct two-bit-per-cell size, the search for the correct set of rules for computing is like finding a needle in a haystack because there are more than a billion possible sets of rules and only one of them works for computing," Wu says.
