Fault-tolerant multiqubit geometric entangling gates using photonic cat-state qubits

2021 · arXiv (Cornell University)

We propose a theoretical protocol to implement multiqubit geometric gates (i.e., the Mølmer-Sørensen gate) using photonic cat-state qubits. These cat-state qubits stored in high-$Q$ resonators are promising for hardware-efficient universal quantum computing. Specifically, in the …
