Recent years have seen the emergence of a number of research groups that aim to advance quantum computing and to develop a skilled quantum software workforce. A particular challenge that must be overcome for safe quantum computing at scale is the creation of robust, expressive, efficient, and tractable formal verification tools. Since there is currently no event dedicated to this pursuit, the first goal of this Dagstuhl Seminar is to bring together a dedicated community of researchers in a single venue. This will give participants an opportunity to identify and discuss the most pressing challenges and promising directions for quantum programming and verification.

Physics-based computing explores alternatives to traditional transistor-based electronics, leveraging nonlinear phenomena in various physical domains to solve real-world problems. This approach extends the concept of analog computing, offering potential for sustainable, energy-efficient solutions in information and communication technologies. The demand for machine learning has surged, driven by advancements like ChatGPT, but the energy cost of digital, transistor-based computing remains high, particularly in large-scale data centers. In contrast, physics-based computing, such as physical reservoir computing, harnesses nonlinear dynamics in systems like magnetic skyrmions, photons, and spin waves to enable more efficient data classification, pattern recognition, and time series predictions. By operating in the nonlinear regime, these physical systems convert input signals into measurable outputs, offering a promising route to edge computing applications in fields like medical diagnostics, autonomous mobility, and smart energy grids. The strength of physical computing lies in its ability to process complex data with minimal energy consumption, without relying on traditional deep learning algorithms. Magnonics, spintronics, and photonics are key fields in this emerging area, offering systems that can serve as powerful, interconnected computational reservoirs. Spintronics, harnessing the electrons’ spin, enables the design of energy-efficient neural networks, while magnonics and photonics provide high-frequency platforms for wave-based computing. The integration of these fields, alongside other platforms such as superconductors, presents new opportunities for developing complex, scalable computing systems that can meet the growing demands of machine learning while advancing sustainable technologies.

System-agnostic black box methods in quantum information include contextuality, communication matrices, device-independent cryptography, and any other approach to quantum information where quantum devices are described as uncharacterized black boxes with inputs and outputs. Some of these approaches, such as contextuality, were developed to address problems in foundations of quantum theory and they are currently finding their way towards applications in quantum information. Others were already developed with applications in mind.

In quantum computing, the use of multiple ion species holds promise for instance by mitigating crosstalk, enabling efficient sympathetic cooling, thereby providing a path toward large-scale trapped-ion quantum computers. Recently other applications such as quantum logic detection of chemical reactions or reduction of uncertainty in multi-species clocks have been demonstrated. This seminar aims to bring together experts from these diverse research areas to explore synergies and foster collaboration in the control of multi-species trapped-ion quantum systems. By addressing shared challenges, such as mixed-species crystal dynamics and the development of efficient quantum logic protocols, we seek to identify synergy and foster collaboration in this rapidly evolving field.
