Quantum computing with quantum-dot cellular automata
نویسندگان
چکیده
Quantum-dot cellular automata ~QCA!, arrays of coupled quantum-dot devices, are proposed for quantum computing. The notion of coherent QCA ~CQCA! is introduced in order to distinguish QCA applied to quantum computing from classical digital QCA. Information is encoded in the spatial state of the electrons in the multidot system. A line of CQCA cells can work as a quantum register. The basic singleand multi-qubit operations can be realized by pulses given to the cell electrodes.
