One-step implementation of a multi-target-qubit controlled phase gate with cat-state qubits in circuit QED

2019 · arXiv (Cornell University)

We propose a single-step implementation of a muti-target-qubit controlled phase gate with one cat-state qubit (\textit{cqubit}) simultaneously controlling $n-1$ target \textit{cqubits}. The two logic states of a \textit{cqubit} are represented by two orthogonal cat states …
