Cavity-Mediated Entanglement Generation Via Landau-Zener Interferometry
Cavity-Mediated Entanglement Generation Via Landau-Zener Interferometry
We demonstrate quantum control and entanglement generation using a Landau-Zener beam splitter formed by coupling two transmon qubits to a superconducting cavity. Single passage through the cavity-mediated qubit-qubit avoided crossing provides a direct test of the Landau-Zener transition formula. Consecutive sweeps result in Landau-Zener-Stückelberg interference patterns, with a visibility that …
