Fig. 3: Phonon-mediated Bell state generation.
From: Quantum communication with itinerant surface acoustic wave phonons
a Inset: pulse sequence for Bell state generation. Main panel: excited state probabilities for Q1 (red) and Q2 (blue) as a function of time. Green lines are results from a master equation simulation. The final state is analyzed at tm = 725 ns (gray dashed line). b Bell state density matrix, absolute values, without readout correction, measured at tm. Red solid lines show values expected for an ideal Bell state; black dashed lines show simulation results including qubit coherence and phonon channel losses.
