  • Quantum gate for carrying out a grover's quantum algorithm and a relative method of performing the interference operation of a grover's quantum algorithm
    Patent number: 7334008
    Abstract: A quantum gate for running a Grover's quantum algorithm using a binary function having a vector basis of n qubits is provided. The quantum gate includes a superposition subsystem, an entanglement subsystem and an interference subsystem. The interference subsystem performs an interference operation on components of entanglement vectors for generating components of output vectors. The interference subsystem performs the interference operation in a very fast manner by using an adder receiving as input signals representing even or odd components of an entanglement vector, and generating a sum signal representing a weighted sum with a scale factor of the even or odd components.
