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.

通过QuCABOoSE，我们挑战了这样一种信念，即与浴的相互作用必然会永远减少量子效应，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，作为实际上由量子环境补充的系统，而不是通过环境受到损害，为量子应用及其物理实现的未开发资源提供新的亮点。通过考虑系统和环境之间的量子相互作用以及系统和环境之间的量子性质，我们的目标有三个主要目标：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。由于联盟的组成和我们个人的专业知识的多样性，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，而不限制我们到一个特定的物理系统。一方面，例如，量子噪声控制和系统浴量子纠缠将作为一个测试平台，探索完整的系统环境量子图像的基本优势，使我们能够探索以前丢失的量子特征如何通过环境反作用反弹。在光谱的另一边，将设计量子协议，例如，由于环境的存在和与环境的相互作用，（重新）激活量子相关性。举一个例子，提出了一种由量子环境提供动力的自净化量子通信（隐形传态）。通过涵盖从基础到应用的范围，该项目的发现推进了我们对开放量子系统的认识，并为现实系统中的量子信息科学提供了一种新的方法。
