摘要

We demonstrate the time-resolved driving of two-photon blue sideband transitions between superconducting qubits and a transmission line resonator. As an example of using these sideband transitions for a two-qubit operation, we implement a pulse sequence that first entangles one qubit with the resonator and subsequently distributes the entanglement between two qubits. We show the generation of 75% fidelity Bell states by this method. The full density matrix of the two-qubit system is extracted using joint measurement and quantum state tomography and shows close agreement with numerical simulation.
