For classical and quantum physical systems, interactions with external environments are usually detrimental to any information encoded within their configurations, with systems found at long times in stable phases independent from their initial conditions. This forms a critical issue for quantum technology applications, with quantum information unavoidably erased overtime in experimental platforms. In classical soft matter featuring glassy dynamics, however, relaxation towards a stable phase can be significantly delayed, which enables a part of the initially encoded information to survive virtually unaffected for a long time. This project will explore open quantum generalisations of classical kinetically constrained models that are known to feature such glassy dynamics, with the goal to discover new physical systems that can store not only classical but also more fragile quantum information.The initial stage will consist of analytical studies of small systems. Those results will then guide adaptations of well-established exact and systematically improvable numerical techniques, for efficient simulations of larger systems. Experimentally feasible setups could become the focus in later years, with outcomes potentially paving a way for a novel type of quantum memories for quantum computing applications.

对于经典和量子物理系统，与外部环境的相互作用通常不利于其配置中编码的任何信息，在稳定阶段长期发现系统独立于其初始条件。这构成了量子技术应用的关键问题，在实验平台中不可避免地删除了量子信息。然而，在具有玻璃动力学的经典软物质中，可以显着延迟对稳定相位的放松，从而使最初编码的信息的一部分能够长期生存。该项目将探索经典动力学模型的开放量子概括，这些模型以这种玻璃动力学为特色，其目标是发现新的物理系统，这些物理系统不仅可以存储经典的量子信息，而且还可以存储更脆弱的量子信息。初始阶段将由小型系统的分析研究组成。然后，这些结果将指导完善的精确和系统改进的数值技术的适应，以有效地模拟较大的系统。实验可行的设置可能会在后来的几年中成为重点，结果可能为新型量子记忆用于量子计算应用提供了一种方法。
