论文摘要
我们表明，在线性量子机中，这是一种驱动的量子系统，与热储层相结合时，储层模式之间的纠缠是不可避免地产生的。这种现象发生在足够低的温度下，是热力学第三定律的核心，是一个简单过程的结果：将驾驶场的能量转化为储层中的激发对成对。对于使用频率$ω_{d} $的驾驶，我们在环境模式之间显示纠缠，其频率满足条件$ω__{i} +ω__{j} =ω__{d} $。我们表明，这种纠缠可以持续使用，而温度可能会明显高于使用边带解决冷却方法的最低可实现的纠缠。
We show that in a linear quantum machine, a driven quantum system that evolves while coupled with thermal reservoirs, entanglement between the reservoir modes is unavoidably generated. This phenomenon, which occurs at sufficiently low temperatures and is at the heart of the third law of thermodynamics, is a consequence of a simple process: the transformation of the energy of the driving field into pairs of excitations in the reservoirs. For a driving with frequency $ω_{d}$ we show entanglement exists between environmental modes whose frequencies satisfy the condition $ω_{i} + ω_{j}= ω_{d}$. We show that this entanglement can persist for temperatures that can be significantly higher than the lowest achievable ones with sideband resolved cooling methods.
