论文摘要
控制开放量子系统是实现当代量子科学技术的重要组成部分。我们通过使用热力学一致的框架来证明这种控制，考虑到驱动器可以改变与环境的相互作用的事实。这种效果被整合到动态方程式中，导致控制依赖性耗散，该关系是开放系统控制的关键元素。控制过程的热力学由能量流向环境的单向流动反映，导致大量熵产生。通过分析熵变化状态到状态转换，例如加热和冷却来显示控制范式。此外，对于完全记忆损失和一组通用的单量子和双量子统一门，证明了在耗散条件下的量子门的产生。
Control of open quantum systems is an essential ingredient to the realization of contemporary quantum science and technology. We demonstrate such control by employing a thermodynamically consistent framework, taking into account the fact that the drive can modify the interaction with environment. Such an effect is incorporated within the dynamical equation, leading to control dependent dissipation, this relation serves as the key element for open system control. Thermodynamics of the control process is reflected by a unidirectional flow of energy to the environment resulting in large entropy production. The control paradigm is displayed by analyzing entropy changing state to state transformations, such as heating and cooling. In addition, the generation of quantum gates under dissipative conditions is demonstrated for both non-unitary reset maps with complete memory loss and a universal set of single and double qubit unitary gates.
