Fast generation of W states of superconducting qubits with multiple Schrödinger dynamics

2016 · Scientific Reports

In this paper, we present a protocol to generate a W state of three superconducting qubits (SQs) by using multiple Schrödinger dynamics. The three SQs are respective embedded in three different coplanar waveguide resonators (CPWRs), …

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 …
