Quantum Computing Concepts with Deutsch Jozsa Algorithm

Poornima Aradyamath, N. M. Naghabhushana, Rohitha Ujjinimatad

In this paper, we briefly review the basic concepts of quantum computation, entanglement, quantum cryptography and quantum fourier transform. Quantum algorithms like Deutsch Jozsa, Shor’s factorization and Grover’s data search are developed using fourier transform and quantum computation concepts to build quantum computers. Researchers are finding a way to build quantum computer that works more efficiently than classical computer. Among the standard well known algorithms in the field of quantum computation and communication we describe mathematically Deutsch Jozsa algorithm in detail for 2 and 3 qubits. Calculation of balanced and unbalanced states is shown in the mathematical description of the algorithm.

Implementation of Quantum Fourier Transform and Its Applications via Quantum-Dot Spins and Microcavity

Dong Ping, Zheng Xiao-Hu, Zhang Gang +1 more

A scheme for implementing discrete quantum Fourier transform is proposed via quantum dots embedded in a microcavity, and then some of its applications are investigated, i.e., Deutsch–Jozsa algorithm and Shor's quantum factoring. In particular, the detailed process of implementing one-qubit Deutsch–Jozsa algorithm and the factorization of N = 15 are given. The microcavity mode is only virtually excited in the whole interaction, so the effective decoherent has slight effect on the current scheme. These schemes would be an important step to fabricate a solid quantum computer.

A Generalization of the Deutsch-Jozsa Algorithm to Multi-Valued Quantum Logic

Yale Fan

We generalize the binary Deutsch-Jozsa algorithm to n- valued logic using the quantum Fourier transform. Our algorithm is not only able to distinguish between constant and balanced Boolean functions in a single query, but can also find closed expressions for classes of affine functions in quantum oracles, accurate to a constant term.
