Experimental method of computing that makes use of quantum-mechanical phenomena. It incorporates quantum theory and the uncertainty principle. Quantum computers would allow a bit to store a value of 0 and 1 simultaneously. They could pursue multiple lines of inquiry simultaneously, with the final output dependent on the interference pattern generated by the various calculations. Seealso DNA computing, quantum mechanics.

Since the NMR experiments cannot prepare pure quantum states and exhibit no quantum entanglement during computation, concerns have arisen about their quantum nature. In particular, it has been proved that the presence of entanglement is a necessary condition for quantum computation.
