New trends in complex quantum systems dynamics 2022
In our Quantum Science era where fault-tolerant quantum devices are still not available but Noisy Intermediate-Scale Quantum (NISQ) devices are accessible, quantum information tools to guide their development play a fundamental role. With the foreseen increasing complexity of available NISQ devices, their classical simulations - which drove their development until now - will soon fail to keep up. There is thus an urgent need for increasingly powerful diagnostic tools that can be applied to quantum devices even in the quantum advantage regime. At the center of the quantum-inspired algorithms lay tensor networks, one of the most powerful paradigms for simulating quantum many-body lattice systems, both in- and out-of-equilibrium, via a representation of the quantum state with tailored variational ansatz wave functions. The results of this workshop will be an essential tool to advance our understanding of dynamical and strong-correlation effects in quantum matter also beyond the NISQ era. Our activity is only possible thanks to a collaborative effort between theory and experiment, and an interdisciplinary approach leveraging the combined expertise of researchers from atomic, molecular, and optical (AMO) quantum technologies (QTs), and high-energy physics. This workshop brings together various key actors who will influence the future development of the leading QTs. The results shown in this workshop will have applications ranging from condensed matter physics over high-energy physics to quantum information theory, facilitating the design of new materials, and even more efficient chemical reactions.
This workshop will show highly collaborative advanced multidisciplinary science and innovative engineering project with the potential to initiate and foster new lines of quantum technologies.
- Quantum simulation and computation: the planned talks in the workshop will show new ways to use existing quantum platforms and apply them to chemistry, condensed matter, and high-energy physics, among others.
- Quantum information science: the planned talks in the workshop will show paradigmatic tools to analyze and study quantum systems for quantum information purposes.
- Quantum sensing: the planned talks in the workshop will show paradigmatic tools to analyze and study magnetic field sensing with super resolution spectroscopy and single-molecule NMR.
The expected impacts of the workshop are:
- Develop a deeper fundamental and practical understanding of systems and protocols for manipulating and exploiting quantum information with the invited and contributed talks and the poster session.
- Identify new opportunities and applications to be fostered through quantum technologies, creating synergies among the most important researchers in the community.
- Enhance interdisciplinarity in crossing traditional boundaries between disciplines to enlarge the community involved in tackling these new challenges, with this in-person activity.

Natalia Ares is an Associate Professor at University of Oxford. Her group follows two main research directions. The more fundamental is focused on exploring how the laws of thermodynamics are revised at the nanoscale. With this aim, they use electromechanical devices which are cooled down to milliKelivin temperatures as nanoscale engines. This research could reveal the cost of quantum information processing and help us understand dissipation and thermalisation in quantum systems, improving the engineering basis of quantum technologies by allowing fully informed choices on device design and optimisation. The other focus of Natalia’s group is the development of machine-learning-based approaches for quantum device control in real time. One of their most recent achievements was to demonstrate fully automatic tuning of semiconductor quantum dots across different device architectures. This work is aimed at reducing the cost, time, and effort involved in the control of quantum devices, which constitute a major bottleneck to the advancement of quantum technologies.

The focus of my research is the development and application of Tensor Network (TN) methods for the numerical simulation of quantum many-body systems. The term TN States has become a common one in the context of numerical studies of quantum many-body problems. It refers to several families that represent different approaches for the efficient description of the state of a quantum many-body system. The paradigmatic application of these techniques, in the context of condensed matter physics, has been the solution of one-dimensional spin problems using Matrix Product States (MPS). This family of states lies at the basis of the Density Matrix Renormalization Group method, which has become the most precise tool for the study of one-dimensional quantum many-body systems in regimes where analytical tools cannot be used. But the potential of TN extends far beyond such problems, and promising extensions include the natural generalization of MPS to higher dimensions and applications to dynamics.

Rainer Blatt’s research focuses on trapped ions as a means to address fundamental questions in quantum optics, spectroscopy, and quantum information science. In the laboratory, individual ions are confined in electromagnetic traps under ultrahigh vacuum, and their electronic states are manipulated and probed using laser beams. Experiments in his group, including the demonstration of quantum gates and highly entangled ion strings, have established that ions are outstanding candidates for quantum bits in a quantum computer. Current research themes include the investigation of light-matter quantum interfaces, the scalability of ion traps for quantum information processing, and the use of trapped ions to simulate quantum processes.

The main research interest of Marcello Dalmonte is the investigation of many-body phenomena motivated by atomic and molecular systems. Such systems pose, from the one hand, new challenges in the spirit of theoretically understanding of complex phases of matter and, form the other hand, an ideal platform to investigate and simulate novel physical phenomena in controlled environment. Lately, his research activity has been mostly devoted to the physics of quantum gases confined in low-dimensionality, and to the development of quantum engineering tools in search for topological phases and emergent gauge symmetries. Research interests: Many-body theory of synthetic quantum systems Theory of low-dimensional quantum systems Entanglement witnesses and measures from a statistical mechanics perspective Tensor network based numerical methods Real-time dynamics of lattice gauge theories Quantum simulation strategies for many-body problems

His research interests are at the intersection of fundamental quantum physics and application of quantum technologies for information processing, communication, sensing, and imaging. Professor Jelezko makes the control of single atomic scale systems in solid state environments possible. Coherent control techniques similar to nuclear magnetic resonance are combined with ultrasensitive optical detection of single atoms. The focus of his pioneering work is on extremely pure, artificially produced diamonds. Jelezko’s research is essential for highly precise sensors and new imaging-technologies.
Jozef Stefan Institute
Nonequilibrium dynamics provides an unprecedented point of view onto the interacting many-body systems. I am fascinated by that approach because it builds the understanding through surprising connections; via thermalization we can learn a lot about the non-ergodic systems, emergent time-scales can actually give information on the interactions between different subsystems, while some extraordinary properties can be triggered or accessed only by driving. Nonequilibrium as a research topic seems inexhaustible since almost all applications of correlated matter use or rely on nonequilibrium situations. In my past projects I addressed diverse set of topics: Reviving integrability in realistic materials. Critical properties of many-body localized (MBL) systems in open setups. Unravelling of interactions between different degrees of freedom in correlated materials. Dielectric breakdown of Mott insulator.

The research group led by Hannes Pichler is interested in theoretical quantum optics, in the context of quantum many-body physics and quantum information processing science. We strive to push the frontier of quantum technology by developing novel applications and quantum computing protocols for near-term quantum devices, focussing on quantum optical systems, such as Rydberg atom arrays, waveguide QED setups, and ultracold atoms. To achieve this goal, our research spans a wide spectrum, from microscopic modeling of the physics of specific quantum devices, to understanding their emergent quantum many-body phenomena. It builds on a variety of analytical and numerical techniques from quantum optics, quantum information, and condensed matter theory.

Martin Ringbauer's research focuses on new ways to use trapped ions for quantum computing and quantum simulation. Current devices use merely a fraction of their potential and trapped ions, in particular, offer a wonderfully rich and highly controllable playground to explore. Making full use of the available Hilbert space, allows us to go beyond linear qubit programming towards efficient problem-tailored quantum information processing. This research spans a wide range from using high-dimensional Hilbert spaces for quantum computing, simulation and error correction, to the development of novel tools for the characterization and certification of quantum devices.
