论文摘要
随着振荡器的真空场波动的变化，振荡器对值的相互作用强度会增长。众所周知的退化参数振荡器已经恢复了对强烈挤压的制度的兴趣，在该状态下，其本征态被挤压为fock状态。由于这些扩增的场波动，最近提出，挤压该振荡器会动态增强Qubit-Photon相互作用。在超导电路实验中，我们观察到量子和振荡器之间在5.5 dB挤压的振荡器之间的分散相互作用增加了两倍，这表明对Qubit-Photon相互作用的原位动力学控制。这项工作启动了挤压光子的振荡器的实验耦合，并谨慎地激发了它们在寻求增强相互作用的实验平台中的传播。
The interaction strength of an oscillator to a qubit grows with the oscillator's vacuum field fluctuations. The well known degenerate parametric oscillator has revived interest in the regime of strongly detuned squeezing, where its eigenstates are squeezed Fock states. Owing to these amplified field fluctuations, it was recently proposed that squeezing this oscillator would dynamically boost qubit-photon interactions. In a superconducting circuit experiment, we observe a two-fold increase in the dispersive interaction between a qubit and an oscillator at 5.5 dB of squeezing, demonstrating in-situ dynamical control of qubit-photon interactions. This work initiates the experimental coupling of oscillators of squeezed photons to qubits, and cautiously motivates their dissemination in experimental platforms seeking enhanced interactions.
