Abstract

We propose a protocol to construct the 35 $$f$$ f -controlled phase gates of a three-qubit refined Deutsch–Jozsa (DJ) algorithm, by using single-qubit $$\sigma _z$$ σ z gates, two-qubit controlled phase gates, and two-target-qubit controlled phase gates. Using this protocol, we discuss how to implement the three-qubit refined DJ algorithm with superconducting transmon qutrits resonantly coupled to a single cavity. Our numerical calculation shows that implementation of this quantum algorithm is feasible within the present circuit QED technique. The experimental realization of this algorithm would be an important step toward more complex quantum computation in circuit QED.
