We show that the Deutsch‐Jozsa algorithm for up to four qubits can be realized with a setup of Josephson charge qubits. While existing proposals for the implementation of the algorithm (for up to three qubits) are based on certain classifications of the oracles, this approach becomes increasingly cumbersome for higher qubit numbers. Here we present a method to implement all balanced functions for the four‐qubit algorithm by a fixed sequence of operations. The free parameters which define the implemented function are the rotation angles of 15 one‐qubit operations.
