Quantum information theory has grown so diverse that it is now impossible to include all its strands in a single event. For this reason, this event will consist of 2 more specialized workshops (at the first and third weeks) with a broad conference in between (second week). We encourage the participants from the workshops to also take part in the conference.

The field of quantum information evolved out of asking fundamental questions about the effect of quantum physics upon information processing. Within this context, the aim of this Workshop will be the discussion of a few topics that have emerged in recent years. An underlying feature of all recent development has been the search to understand, from more intuitive principles, why quantum mechanics describes nature so well. On one hand, this gave rise to the device-independent approach to quantum information, where solely by interacting through classical, experimental data we can manipulate quantum mechanical devices for certain tasks without needing to rely on any particular assumptions about implementations. On the other, it has shown that in order to understand quantum theory, unavoidably we have to revisit our most basic notions of cause and effect, what naturally led to a very promising direction of research, connecting causality, artificial intelligence and machine learning with problem in quantum information.


The workshop will cover on the following topics (but will not be limited to): Quantum correlations, Quantum cryptography, Quantum thermodynamics, Quantum Causality, Quantum machine learning, Quantum many-body systems, Quantum information-inspired experiments.


The workshop will have a key-note talk of 1 hour per day. Every other participant is also a potential speaker and can also give a talk about their work: we will have available an auditorium, 2 seminar rooms and 2 discussions rooms. To give a minimum structure to the workshop we have scheduled in advance 17 talks (30 minutes each). To maximize interactions and collaborations we expect that most of the other talks will be self-organized by the participants during the event (including potential parallel sessions and discussions).

The discovery that the microscopic laws of physics allow for a fundamental speedup over any classical approach to computation has arguably been the single most important boost to quantum information theory. After the initial excitement, there was a period of increased scepticism about whether the daunting engineering challenges of actually constructing a quantum computer could be overcome. However, significant progress e.g. in solid-state based qubit implementations over the past few years have increased the interest in quantum computation the point where now several leading technology corporations are now funding projects with the goal of demonstrating computational quantum supremacy. In parallel to that quantum information has also interconnected with several other areas, being nowadays an essential tool in other areas within physics (e.g. condensed matter physics, gravity, thermodynamics) as well as outside (e.g. machine learning, statistical and causal inference). The conference will cover topics that are of particular recent interest and that represent the broadness of quantum information.


The conference will cover on the following topics (but will not be limited to):Quantum computation, Quantum machine learning, Quantum cryptography, Quantum information and condensed matter physics, Quantum information and gravity, Quantum thermodynamics, Quantum information-inspired experiments.


There will be space available for those presenting posters.  For the program click here and for the abstracts here

There has been an extremely fruitful interchange of ideas between quantum information and the field of convex geometry.

Convex optimization theory, for instance, is overtly concerned with the applied problem of solving certain optimization problems that are important e.g. in engineering. More interestingly, though, it is also provides increasingly important theoretical tools with applications to computational complexity theory. One major reason is that the convex optimization technique of semi-definite programming (SDP) is one of the most powerful methods for systematically deriving relaxations that give approximate solutions to otherwise computationally hard problems. For many tasks e.g. in graph theory or signal analysis, SDPs give rise to the best-known approximate algorithms.

In turn, since the set of states and operations in quantum theory are defined by semi-definite constraints, it is plausible that SDPs are relevant in this context. This is indeed true, and SDPs provide powerful techniques e.g. for identifying and quantifying entanglement. However, the past few years have seen a reversal in the flow of ideas in that several researchers from quantum information used physics-inspired concepts to contribute to convex optimization theory. Examples include the high-profile solution of a long-standing open problem showing that there is no efficient SDP formulation of the Traveling Salesperson Problem; the development of converging hierarchies of SDP-relaxations to problems specified by polynomials in non-commuting variables; the use of methods from quantum information to develop the first general theory of low-rank matrix recovery using SDPs; and the very recent discovery that quantum computers offer exponential speedups for solving certain SDPs.

Lastly, there is increased interest in exploring probabilistic theories that generalize quantum theory. They are naturally described in terms of "states" and "effects", which form pairs of dual convex cones. A significant amount of research has gone into characterizing the physical properties of such theories in terms of the convex geometry of these sets.


The workshop will have a key-note talk of 1 hour per day. Every other participant is also a potential speaker and can also give a talk about their work: we will have available an auditorium, 2 seminar rooms and 2 discussions rooms. To give a minimum structure to the workshop we have scheduled in advance 16 talks (30 minutes each). To maximize interactions and collaborations we expect that many other talks will be self-organized by the participants during the event (including potential parallel sessions and discussions).
