The generalized amplitude damping (GAD) quantum channel implements the interaction between a qubit and an environment with arbitrary temperature and arbitrary interaction time. Here, we implement a photonic version of the GAD for the case of infinite interaction time (full thermalization). We also show that this quantum channel works as a thermal bath with controlled temperature.

光子量子位的完全热化

广义振幅阻尼（GAD）量子通道实现了量子位与任意温度和任意交互时间的环境之间的交互。在这里，我们为无限交互时间（完全热化）的情况实现了 GAD 的光子版本。我们还表明，该量子通道可用作温度受控的热浴。
