   The Deutsch–Jozsa problem is specifically designed to be easy for a quantum algorithm and hard for any deterministic classical algorithm. It is a black box problem that can be solved efficiently by a quantum computer with no error, whereas a deterministic classical computer would need a exponential number of queries to the black box to solve ...

   What is Deutsch algorithm?

   • The Deutsch algorithm is a quantum algorithm capable of determining the value of \\(f_{i}(0) \\oplus f_{i}(1)\\) by making only a single query to a quantum oracle for \\(f\\). The oracle can be expressed as a unitary operator \\[U_{f} | x>_{A} | y >_{B} = | x >_{A} | y \\oplus f(x) >_{B}\\]

   What is the Deutsch-Jozsa algorithm?

   • The Deutsch–Jozsa algorithm solves a black-box problem that requires exponentially many queries to the black box for any deterministic classical computer, but can be done with a single query by a quantum computer.

   What is the difference between Deutsch-Jozsa algorithm and quantum algorithm?

   • Whereas quantumly the Deutsch-Jozsa algorithm requires only the transmission of a single n + 1 qubit message by Alice, to which Bob replies with a n qubit message. So there is an exponential reduction in the amount of information transfer required to solve an instance of Deutsch's problem.

   What is the Oracle in Deutsch's algorithm?

   • The oracle in Deutsch's algorithm is su ciently simple that we can explicitly express each possible option, but frequently in quantum computing problems are framed in terms of oracles, even when this is not the case.

   Overview. Quantum algorithms are usually described, in the commonly used circuit model of quantum computation, by a quantum circuit that acts on some input qubits and terminates with a measurement. A quantum circuit consists of simple quantum gates, each of which acts on some finite number of qubits.

   Deutsch’s algorithm was the rst algorithm that demonstrated a quantum advantage: speci cally a reduction in query complexity compared to the classical case. The Deutsch-Jozsa algorithm generalises Deutsch’s algorithm, and reveals the possibility of exponential speed-ups using quantum computers. 18/18
