Quantum Coherence Activation By Open Systems and Environments

通过QuCABOoSE，我们挑战了这样的信念，即与浴缸的相互作用必然会永远减弱量子效应，从而限制量子科学和技术领域的进步。我们雄心勃勃的愿景是建立开放系统，作为事实上得到量子环境补充的系统，而不是通过环境而受到损害，为量子应用及其物理实现的未开发资源带来新的曙光。通过考虑系统和环境之间的全量子本质和量子相互作用，我们针对三个主要目标：O1噪声激活的量子关联、O2环境辅助的量子算法和O3多平台噪声表征。由于该联盟和我们的个人专家组成的多样性，我们能够从理论和实验相结合的角度来解决上述研究目标，而不会将我们限制在特定的物理系统中。一方面，量子噪声控制和系统浴量子纠缠将作为一个试验台，探索完整的系统环境量子图景的基本优势，使我们能够探索以前丢失的量子特征如何通过环境反向作用反弹。在光谱的另一边，量子协议将被设计出来，例如，由于环境的存在和相互作用而(重新)激活量子关联。举个例子，一种由量子环境提供动力的自净化量子通信(隐形传态)被提出。通过涵盖从基础到应用的范围，该项目的发现促进了我们对开放量子系统的了解，并为现实系统中的量子信息科学提供了一种新的方法。

With QuCABOoSE, we challenge the belief that interactions with a bath necessarily diminish quantum effects forever and, thereby, restrict the progress in the fields of quantum science and technology. Our ambitious vision is to establish open systems as systems that are, in fact, supplemented by a quantum environment, rather than being impaired through the environment, shining a new light on an untapped resource for quantum applications and their physical implementations. By considering the full quantum nature of and quantum interaction between systems and environments, we target three main objectives: O1 noise-activated quantum correlations, O2 environment-assisted quantum algorithms and O3 multiplatform noise characterization. Because of the diverse composition of the consortium and our individual expertises, we are able to tackle the aforementioned research goals from a combined theoretical-experimental perspective, without limiting us to a specific physical system. On the one hand, quantum-noise control and system-bath quantum entanglement, for example, will function as a testbed to probe the fundamental advantages of a full system-environment quantum picture, allowing us to explore how previously lost quantum features can rebound through environment backactions. On the other side of the spectrum, quantum protocols will be devised that, for example, (re-)activate quantum correlations due to the presence of and interaction with an environment. To name one application, a self-purifying quantum communication (teleportation), powered by a quantum environment, is proposed. By covering the range from fundamental to applied, the project’s findings advance our knowledge of open quantum systems as well as offer a fresh approach to quantum information science in realistic systems.
