Накратко на български

Квантовите ефекти в пространството и времето се изследват чрез анализ на начина, по който информацията се предава и трансформира. Това помага за по-доброто управление и предвиждане на сложните процеси в бъдещите квантови технологии.

Taming, controlling and harnessing quantum complexity

In the past decade, we have witnessed a proliferation of devices that leverage quantum effects and promise to fundamentally transform the technological and industrial landscape. Unlike previous paradigm shifts in the area of quantum technologies -- like the development of the transistor – which revolved around the speed-up and facilitation of classical tasks, the current generation of quantum technologies goes one important step further: it aims at harnessing the fundamentally different way that information itself is expressed, transformed, and processed in the quantum realm. The formidable practical and foundational advances of the past years notwithstanding, much work still lies ahead in order to scale, control and harness quantum effects to the fullest extent, consequently making their power routinely and reliably available. To date, most research on exploitable quantum phenomena has focused on entanglement as the basis for quantum technologies. This is a spatial quantum resource, in the sense that it describes quantum correlations that are shared by spatially separated parties. In complex quantum processes and devices, quantum information will not only be shared though, but also processed and transmitted, leading to quantum correlations in both space and time. Consequently, the TaQC project aims to widen the scope and provide a comprehensive understanding of spatio-temporal quantum effects and develop the means to characterise, control and predict them. In particular, the project focuses on three main questions: (i) how do realistic constraints condition the distribution of spatio-temporal entanglement in a quantum process? (ii) how can general quantum processes be characterized and what can be learned about them efficiently? And (iii) how can optimal models for quantum processes be constructed and their resourcefulness be estimated? The development of a robust theoretical framework to address these questions relies on insights from quantum information theory, quantum metrology, the theory of open quantum system dynamics as well as higher order quantum maps. Its implementation will provide a holistic understanding of quantum effects as they occur in complex quantum processes, and help pave the way towards their reliable and sustainable exploitation.

Цел на проекта

Quantum processes hold tremendous potential for the development of novel technologies, as epitomized by the recent proliferation of commercially available quantum devices. To date, most research and innovation in the field has focused on spatial quantum effects – most prominently entanglement -- leaving quantum effects in time an as-of-yet untapped resource. Progress in understanding such effects has been hindered by the inherent complexity of quantum memory and the lack of an adequate conceptual framework. This, in turn, has prevented the development of tools to probe, predict and compress general quantum processes. This action aims to overcome these hurdles and answer the following fundamental questions: What kinds of quantum memory effects are physically possible? How can they be efficiently probed? How can predictive models for quantum processes be constructed? Answers to these questions will be obtained by combining a novel, fully-general approach to the dynamics of open quantum systems, with a proven, systematic construction of memory-minimal models of classical phenomena. The ensuing framework and tools will engender bounds on the strength and distribution of quantum memory, enable the construction of predictive models for complex quantum processes, and render their characterization experimentally tractable. These crucial innovations will pave the way to a reconceptualization of quantum information processing that provides the means to harness the full potential of quantum processes, both in space and time. As a result, the outcomes of the action are expected to find long-term application in a wide array of fields, ranging from quantum information to complexity theory and bio-chemical processes.The research will be carried out at Trinity College Dublin, in the perfectly suited group of Felix Binder, who is a leading expert working at the interface of quantum thermodynamics, classical complexity theory and quantum information theory.
