Quantum Information

Join us for a pioneering joint workshop between renowned research institutions in Munich and Waterloo! This exciting event will focus on the topic of quantum simulation, with additional talks delving into various subjects of quantum science and technology. Designed to include researchers across different levels, from group leaders, postdoctoral fellows, and PhD students, this inaugural collaboration aims to unite scientists from both locations, fostering valuable networking opportunities and promoting interdisciplinary collaboration. Don't miss this extraordinary opportunity to connect, exchange ideas, and shape the future of quantum research together! 
 

Understanding causality is fundamental to science and inspires wide-ranging applications, yet there are several distinct notions of causation. Recently, there have been important developments on the role of causality in quantum physics, relativistic physics and their interplay. These have unearthed a plethora of fascinating open questions regarding the nature of causation, emergence of space-time structure and the limits of quantum information processing. At the same time, causal reasoning has become an important tool in machine learning and statistics, with applications ranging from big data to healthcare. This conference brings together experts from different areas of physics working on questions related to causality, as well as selected researchers who bridge the gap between fundamental research and current industrial applications. The aim of the conference is to provide a venue for cross-pollination of these ideas through scientific exchange between these communities. The conference will focus on the following facets of causality:

• Quantum and classical causal inference

• Indefinite causal order and quantum reference frames

• Causality in quantum field theory and quantum gravity

• Experiments and applications of causality

Causalworlds 2022: The interface between quantum and relativistic causality, foundations and practicalities
Organised at ETH Zürich in 2022. Website: https://causalworlds.ethz.ch/"

The dialogue between quantum information and quantum matter has fostered notable progress in both fields. Quantum information science has revolutionized our understanding of the structure of quantum many-body systems and novel forms of out-of-equilibrium quantum dynamics. The advances of quantum matter have provided novel paradigms and platforms for quantum information processing.
This conference aims to bring together leading experts at the intersections of quantum information and quantum matter. Key topics include: (i) quantum error correction, (ii) quantum dynamics, and (iii) quantum simulation.

Organizers:

Timothy Hsieh, Perimeter Institute

The workshop marks the halfway point of the similarly named (FoQaCiA, pronounced "focaccia") collaboration between researchers in Canada and Europe, funded as part of a flagship partnership between NSERC and Horizon Europe. 

https://www.foqacia.org/

The goal of FoQaCiA is to develop new foundational approaches to shed light on the relative computational power of quantum devices and classical computers, helping to find the "line in the sand" separating tasks admitting a quantum speedup from those that are classically simulable.

The workshop will focus on the four central interrelated themes of the project:
1. Quantum contextuality, non-classicality, and quantum advantage
2. The complexity of classical simulation of quantum computation
3. The arithmetic of quantum circuits
4. The efficiency of fault-tolerant quantum computation

Our view is that the future success of quantum computing critically depends on advances at the most fundamental level, and that large-scale investments in quantum implementations will only pay off if they can draw on additional foundational insights and ideas

Quantum position verification (QPV) schemes use the properties of quantum information and the relativistic signalling bound to verify the location of an object (sometimes called a “tag”) to distant observers in an environment that may contain would-be spoofers. The guarantee is based on the assumptions of the underlying security model; various theoretically and practically interesting security models have been proposed. The area is attracting increasing interest, with new theoretical developments in security analyses, emerging experimental studies of QPV systems, and recently discovered surprising and intriguing connections to topics in quantum gravity. A workshop on QPV will be held at the Perimeter Institute for Theoretical Physics.

The workshop will cover topics related to all aspects of QPV, including, but not limited to:

• Theoretical developments related to the security of QPV schemes, including development or refinement of security models, proofs of security within given models, tradeoffs between security and efficiency, and Experimental studies of QPV and theoretical work aimed at developing practical QPV schemes.
• QPV’s relationship to other cryptographic tasks and primitives.
• QPV’s relationship to holography and quantum gravity.

In the first edition of the meeting, CATMIN (Cold ATom Molecule INteractions) was a new satellite meeting of ICPEAC devoted to the study of atomic and molecular systems, where long-range interactions and the extreme properties of highly excited electrons produce new physics and lead to new technologies. CATMIN's objective is to strengthen the links between cold atom physics, molecular physics, chemistry and condensed matter physics, so that new concepts and breakthroughs can emerge. Ions, atoms and molecules are naturally made quantum systems that can be controlled with light and low frequency electromagnetic fields, thus lending themselves to precision investigations and use in quantum technologies. The second CATMIN conference will be held a few days before the ICAP, which is a major conference in AMO physics, with the idea that scientists can attend both meetings. The CATMIN meeting will be a two-day conference held at the Perimeter Institute in Waterloo, ON, centered on Rydberg-atom physics, cold ion physics and the interplay between these experimental platforms. Rydberg atom physics is experiencing a renaissance due to the application of the exaggerated properties of highly excited atoms for quantum information and quantum simulation. Rydberg states can even be observed in solids which is a subject of increasing interest. Cold ions, similarly, are exciting for quantum simulation and computing, becoming one of the central platforms in the race to build a quantum computer. Many exciting developments are also in progress in the area of cold-molecules. Long-range interactions open up fields of research such as the photo-association of cold atoms to form ultra-cold molecules, and the excitation of Rydberg molecules demonstrating novel kinds of molecular bonding. Strong long-range interactions in all the systems permit the investigation of the few-body and many-body regimes, including the few- to many-body transition. The conference aims to share the latest developments and results in these exciting fields among the various ICAP communities as well as the broader physics and chemistry communities. Overall, the conference can forward quantum science and the application of quantum science, which furthers these fields of research by concentrating interest to attract people and resources to the field.

There has been a surge of interest in indefinite causal structure the idea that cause and effect can no longer be sharply distinguished.  Motivated both by experimentation with quantum switches and quantum gravity there can be situations in which there is no matter-of-the-fact as to what the causal structure of spacetime is.  This meeting will bring together workers in Quantum Foundations and Quantum Gravity in both theoretical experimental physics to discuss the state of the art of current research and set new directions for this emerging subdiscipline.
