A high-fidelity method for a single-step $N$-bit Toffoli gate in trapped ions

Juan Diego Arias Espinoza, Koen Groenland, Matteo Mazzanti +2

Conditional multi-qubit gates are a key component for elaborate quantum algorithms. In a recent work, Rasmussen et al. (Phys. Rev. A 101, 022308) proposed an efficient single-step…
