Abstract

Entangling ions of different species is an important prerequisite for transferring quantum information between them. Thus we can choose to perform operations on the best suited species, harnessing their individual strengths. We use the \(\sigma _z\) geometric phase gate that only requires a single pair of Raman beams to perform a gate simultaneously on two different species. In a first test of the scheme we perform the gate between two different isotopes of calcium: \(^{40}\mathrm {Ca}^+\) and \(^{43}\mathrm {Ca}^+\). These results were published in [1] and are also discussed in parts in [2]. In a proof-of-principle experiment we then realise the same gate on two different atomic species—\(^{43}\mathrm {Ca}^+\) and \(^{88}\mathrm {Sr}^+\).
