Since their creation in 1966 by Jean Tran Thanh Van, the Rencontres de Moriond bring together physicists for in-depth discussions in a friendly and relaxed atmosphere. The 56th Rencontres de Moriond session devoted to QCD AND HIGH ENERGY INTERACTIONS will take place in La Thuile from Saturday, March 25th to Saturday, April 1st, 2023.

The meeting is intended to promote fruitful collaboration between experimentalists and theorists and between various institutions, by bringing together a limited number of particle physicists in beautiful and inspiring surroundings.

The scientific scope of the HQT workshop will be to bring together people from slightly different communities aiming at fruitful discussions and exchange of ideas. The scientific scope is at the intersection between spin qubits, hybrid semiconductor-superconductor devices and superconducting circuits/qubits. Leading people from all fields will present their latest result. In addition, two poster sessions where students and postdocs can present their results will take place.

Mathematical Sciences Research Institute (MSRI)

This workshop is about the recent MIP*=RE result from quantum computational complexity, and the resulting resolution of the Connes embedding problem from the theory of von Neumann algebras. MIP*=RE connects the disparate areas of computational complexity theory, quantum information, operator algebras, and approximate representation theory. The techniques used in the proof of MIP*=RE, such as self-testing and probabilistically checkable proofs, are well-known in theoretical computer science and quantum information, but are unfortunately completely foreign in operator algebras and approximate representation theory. Likewise, the tools of operator algebras and approximate representation theory are mostly unfamiliar in theoretical computer science and quantum information. This has made it challenging to translate the MIP*=RE result and the techniques used to prove it into a form digestible to operator algebraists. The aim of this workshop is to bridge this divide, by giving an in-depth exposition of the techniques used in the proof of MIP*=RE, and highlighting perspectives on the MIP*=RE result from operator algebras and approximate representation theory. In particular, this workshop will highlight connections with group stability, something that has not been covered in previous workshops. In addition to increasing understanding of the MIP*=RE proof, we hope that this will open up further applications of the ideas behind MIP*=RE in operator algebras.

Black holes are playing an ever increasing role in fundamental physics, from information theory to quantum gravity and holography. They are now under active investigation in many important branches of observational, theoretical and mathematical physics. In particular, they have stimulated important advances in the computation of entanglement entropies in large N conformal field theory and in various aspects of gauge theory/gravity duality. This workshop gathers researchers working on mathematical problems related to the holographic description of black holes, in its quantum aspects. The workshop will stimulate progress at this cutting edge of theoretical high energy physics.

A main objective of QCD Evolution Workshop is to provide a forum to discuss the recent scientific accomplishments in areas such as Transverse Momentum Distributions (TMDs), Generalised Parton Distributions (GPDs), and small-x physics, together with advances in perturbative and non-perturbative techniques within QCD, such as lattice QCD and effective field theory techniques. In doing so this workshop also aims to support and guide the physics programs at facilities such as Jefferson Lab, the Relativistic Heavy Ion Collider (RHIC) at Brookhaven National Lab, Fermi National Accelerator Laboratory, and the Large Hadron Collider (LHC) complex at CERN. The workshop is also central to the building of the next-generation nuclear physics facility in the US, the Electron Ion Collider (EIC).

ICMS - International Centre for Mathematical Sciences

Quantum technology is a vibrant discipline of research with numerous applications in all areas of science. The particular interest for this workshop lies in the area of quantum information and the control of quantum systems. While traditionally these disciplines have worked with finite-dimensional mathematical models for the sake of simplicity and since it has appeared sufficient, ever-growing physical systems and progress in experimental realisations make it natural to ask what happens in infinite dimensions: in the end, for large systems, infinite-dimensional approximations can often simplify the description of the finite-dimensional system; moreover, many systems are simply not finite-dimensional and hence a reliable mathematical description is needed. In this research workshop we would like to look at a number of current research themes in the wider area of quantum information such as robust quantum control, long-term stability of quantum systems, entanglement breaking channels and the divisibility of channels. By gathering experts from these areas, this workshop will stimulate discussions and cross-pollination, to look at common structures and frameworks, and to study the transition from finite to infinite dimensions and convergence properties in all of them.

There are significant efforts and investments (from both government and industry) to jump start the quantum information-based industry in the last decade. While quantum communication and computing are shifting from laboratory-based demonstrations to physical deployment from land to space, critical challenges remain in scaling the quantum network, computer, and storage capabilities for making quantum information technology a practical proposition. The specialized materials development required for exploiting superposition and entanglement in various systems is one major bottleneck. This symposium seeks to bring together key international researchers working directly at the frontline of research to solve the material critical challenges for scalable quantum information technologies. Through the confluence of ideas and disciplines, we hope to achieve greater awareness and support for this important field and engender new and productive collaborations that could accelerate the materials development that is crucial to propel the quantum industry into viable reality.

Join us for an incredible three-day event taking place on June 27-29, 2023. Engage intimately with key government, academic, and industry leaders as we shape the future of quantum together. Brought to you by the Air Force Research Laboratory (AFRL), Air Force Office of Scientific Research (AFOSR), Griffiss Institute, and the Innovare Advancement Center. This event is part of a global connectivity initiative to build an open ecosystem of government, academic, and industry collaborations and shape the future of quantum innovation for the U.S. and its’ partners.

Attosecond (10−18s) science has emerged from the study of the interaction of matter with intense laser fields, and it is the natural successor of femtochemistry [1]. Its main objective is to resolve and ultimately control electron dynamics in real time. Electrons play a key role in photosynthesis, destroy or modify molecules, and can be used for information processing in human-made devices. This wide range of applications and huge potential for attosecond imaging of matter has made it a hugely popular and expanding area. Unfortunately, this rapid growth has led to a vast, fragmented methodological landscape, with many conflicting views.

This conference will bring together different communities - particle physics, atomic and molecular physics, and quantum technologies - to foster new research projects and collaborations across Switzerland and internationally to advance in the search for new physics beyond the Standard Model exploiting emerging quantum technologies.

Max Planck Institute for the Physics of Complex Systems

Nordita, Stockholm

QFT techniques are routinely applied to systems with boundaries and defects, often with remarkable success. However, in systems with strong interactions many of the important questions remain intractable. Luckily, the rapid development of novel approaches to strongly-interacting QFTs opens a new avenue to study boundaries, defects and impurities. Prominent examples include the Anti-de-Sitter/Conformal Field Theory correspondence and holographic duality, integrability, the conformal bootstrap, non-perturbative supersymmetry methods, the use of entanglement entropy and other quantum information measures, anomalies and higher-form symmetries, hydrodynamics of QFTs, and more.

Coherent control aims to steer quantum systems towards desired final states through its interaction with light. Recent years have witnessed rapid acceleration of research activity in the field. Along with new theoretical control strategies, latest advances in nonlinear optics and ultrafast laser technology have enabled spatial and temporal coherence of light to be extended through to the UV and X-ray regions. The possibility of engineering and tailoring coherent waveforms is paving the way to novel discoveries in a number of scientific disciplines at the interface between physics, chemistry and biology. Promising applications include the development and control of quantum materials and metamaterials, control of chiral matter, and high-precision spectroscopy on ultrafast time scales.

The conference will focus on the two paradigms, quantum control and quantum technology, which are highly interconnected and merging together very rapidly. The development of the general principles of quantum control is essential for future quantum technology. Quantum control deals primarily with the interaction of laser light with matter. The objective of the control is to modify the state of matter or the course of a chemical or physical process. These control tasks require “intelligent” light fields, which have to be highly controllable in frequency, phase, and intensity.

Quantum non-stationary systems continue to be a living and very interesting part of quantum physics, uniting researchers from many different areas. However, the number of special scientific meetings devoted to them is rather limited. One such meeting was the International Seminar Time-Dependent Phenomena in Quantum Mechanics, organized by Manfred Kleber and Tobias Kramer in 2007 at Blaubeuren, Germany. Another meeting was the International Workshop on Quantum Non-stationary Systems, held on October 19-23, 2009 at the International Center for Condensed Matter Physics (ICCMP) in Brasilia, Brazil. It was organized by Viktor Dodonov, Vladimir Man'ko and Salomon Mizrahi. Now, we have decided to organize the Second International Workshop on Quantum Non-Stationary Systems at the International Center of Physics (ICP) in Brasilia, Brazil, on August 28 - September 1, 2023. In particular, one of the goals of this event is to celebrate the 75th anniversary of Prof. Viktor Dodonov and 50 years of his research and teaching activities. We expect to have about 40 invited talks in the hybrid format, made by distinguished researchers from more than 15 countries. A few contributed talks and an unlimited number of poster presentations are also highly welcome. Selected works will be published in the book of proceedings with ISSN in online and print versions. All the presentations will be transmitted online on YouTube and saved in the channel of the International Center of Physics.

In order to maximize the impact of using quantum technology to probe fundamental interactions it is critical that each community improves its knowledge of the other discipline. We plan to bring in world experts in quantum technologies and particle physics in order to discuss how the recent progress in the precision front of quantum sensors could be used to search for new physics and study fundamental interactions. We plan to invite practitioners of both AMO and particle physics to sit together and learn from each other about the state of the art and to discuss how quantum sensors can be used to search for “old” and “new” types of Beyond the Standard Model physics.

Topology is likely to be featured prominently in any truly useful quantum computation scheme. The hurdle of scalable fault-tolerance is insurmountable with the current incremental progress -- while it is possible to engineer systems supporting hundreds of physical qubits, applications beyond academic interest require millions of qubits to implement robust error correction. Topological quantum computation (TQC) relies upon the preparation of topological phases of matter supporting non-abelian anyons to perform inherently fault-tolerant operations. As errors are corrected at the hardware level through the topological nature of anyons, the problem of scalability is simultaneously overcome. On the other hand, despite years of effort we still don't have unassailable confirmation that non-abelian anyons exist. This workshop will bring together researchers in a diversity of fields in and around TQC for the purpose of broadening and deepening the subject, with an eye towards accelerating the realization of scalable technology.

What will quantum computers be useful for once we have them? Machine learning and optimization would be important applications if quantum computers were useful for them, but the level of quantum benefit is unknown. One aim of the workshop is to bring together experts in classical and quantum machine learning to discuss the role of mathematical proof as well as experimentation in understanding these topics. A second aim is to explore how classical machine learning techniques can help us build better quantum computers.

The ability to create and manipulate complex quantum states offers the potential for dramatic increases in computational power, measurement sensitivity, and information security. Understanding the dynamics of such entangled many-body states raises a number of mathematical and physical questions, as such states often lie beyond standard approximate descriptions used in different areas of physics. This workshop is devoted to the related problems of how quantum and classical computers can be used to attack important problems in many-body quantum mechanics across application domains. While the faithful representation of full many-particle Hilbert spaces on a classical computer is exponentially costly, efficient approximate representations for specific purposes have been discovered, such as tensor networks. Studying the dynamics of quantum computers in the current NISQ area leads naturally to questions of robustness and control.

The symmetries of classical mathematical objects form a group. In the past several decades, we have seen new quantum mathematical objects like von Neumann algebras and quantum field theories whose symmetries are best described by tensor categories. One reason for this is that these mathematical objects naturally form higher categories, and thus their endomorphisms naturally form higher monoidal categories. In this sense, we view fusion categories as objects which encode quantum symmetries. Subfactors are a rich source of examples of exotic unitary fusion categories, and conversely, every unitary fusion category arises from a subfactor. This correspondence leads to deep mathematical connections between these fields. These mathematical objects are also intimately related to conformal field theory and topological phases of matter, which give topological quantum field theories, in which higher categories play an important role. The purpose of this workshop is built on the 2014 and 2018 BIRS workshops on subfactors and fusion categories, with the goal of studying these objects through a higher categorical lens. To do so, we will bring together world experts from subfactors, fusion categories, higher categories, and mathematical physics to further develop the deep and rich connections between these fields.
