本地驾驶局域驱动对A模和B模的直接影响是单模压缩。在二分系统的约化动力学中的耗散将这种单模压缩转换为双模压缩（当观察对称和反对称模式时）或纠缠（当观察本地模式A和B时）。这种效应在很宽的温度范围内都能发现。即使对于仅驱动模式A的情况，也可以找到产生显著纠缠的合适的脉冲形状。这些发现对当前的超导电路实验具有潜在的相关性。它们还为无需显式状态转移的心灵传输开辟了新的可能性。
local driving. The immediate effect of local driving on modes A and B is single-mode squeezing. Dissipation in the reduced dynamics of the bipartite system transforms this single-mode squeezing into two-mode squeezing (when viewing symmetric and antisymmetric modes) or entanglement (when viewing local modes A and B). This effect is found over a wide temperature range. Suitable pulse shapes yielding significant entanglement can be found even for the case of driving only mode A. These findings are of potential relevance for current experiments with superconducting circuits. They also open new possibilities for teleportation without an explicit state transfer.
