论文摘要
在这里，我们展示了信息为信息助长的量子引擎的完整周期的实现。该发动机是Szilard发动机的量子版本，其中信息用于从环境中提取热量并将其完全转化为工作。在我们的实验中，这项工作用于使重量（最初处于基础状态）达到激发状态。在周期的每个步骤之后，我们测量发动机每个组件的能量和状态，并将它们与理论预测进行比较，以表明周期是高精度实现的。我们还执行实验，以表明发动机在提取热量后与环境很好地隔离，并且我们测量了重量的熵，以显示热量的全部转化为工作。因此，我们成功地证明了信息可以用作单砂发动机的燃料。
Here, we show the implementation of a complete cycle of a quantum engine fuelled by information. This engine is a quantum version of the Szilard engine, where information is used to extract heat from the environment and fully convert it into work. In our experiment, this work is used to make a weight, initially in the ground state, reach its excited state. We measure the energy and the state of each component of the engine, after each step of the cycle, and compare them with the theoretical prediction to show that the cycle is implemented with high precision. We also perform experiments to show that the engine is well isolated from the environment after the heat extraction, and we measure the entropy of the weight to show the full conversion of heat into work. Thus, we successfully demonstrate that information can be used as a fuel for single-reservoir engines.
