International Conference

Quantum Information and Probability: from Foundations to Engineering (QIP26)

The Växjö-26 conference on quantum foundations will take place in 2026, June 9-12 (arrival June 8 and departure June 13). The Växjö annual conference is the longest-running series on quantum foundations. It will feature invited talks (30 min, including questions) and contributed talks (20 min, including questions).

The quantum information revolution drives both technology and foundational research. We invite contributions on quantum foundations and their applications, including quantum information, probability, measurement theory, as well as biology, cognition, decision making, and medicine.

Conference Fee: All participants, including invited speakers and organizers, are kindly requested to pay the conference fee.

Contributed talks will be selected based on the submitted abstract. Please begin by registering (without paying the fee) and submitting your abstract. If accepted, you can then complete the registration by paying the organizational fee. Graduate and postgraduate students are encouraged to submit a poster, as posters generally receive greater visibility than talks in parallel sessions. The journal Entropy supports the awards for the two best posters with 350 and 150 Swiss francs respectively, conference proceedings will be published in the special issue of Entropy, see https://www.mdpi.com/journal/entropy/special_issues/V1Z7NV7316

Deadline för abstract submission: April 25, 2026

Satellite Workshops

Workshop “Quantum Logic meets Contextuality"

Organizer - Karl Svozil

Invited Speakers: A. Cabelo*, P. Grangier*, M. Navara, M. Pavičić, K. Svozil, R. Ramanathan

Summary: Even in antiquity, philosophers such as Aristotle and the Stoic Chrysippus sought to formalize the ``laws of thought'', grounded in their belief that logos---reason or rational principle---reflects, at least in part, the structure of nature itself.

In modern times, George Boole, Charles Sanders Peirce, and Ludwig Wittgenstein laid the foundations for propositional logic by introducing formal logical operations and relations. Their work systematized reasoning into symbolic frameworks amenable to mathematical analysis.

For any logical formalism to be genuinely useful---especially in describing physical reality---it must find grounding in the natural sciences. In the 20th century, John von Neumann and Garrett Birkhoff pioneered an ambitious program: to reinterpret quantum mechanical propositions as elements of a non-classical logical structure. Their quantum logic replaced the Boolean algebra of classical physics with an orthomodular lattice, reflecting the empirical constraints of quantum theory.

Subsequent work by Simon Kochen and Ernst Specker rigorously explored the consequences of this shift. They demonstrated that certain classical logical tautologies---such as those relying on the assumption of simultaneous definite values for all observables---fail in the quantum realm. Moreover, they proved that quantum logical structures cannot be faithfully embedded into classical Boolean algebras, thereby ruling out hidden-variable interpretations that preserve classical logic.

Quantum logic thus provides a systematic framework for (de)constructing sets of maximally co-measurable observables, revealing their intrinsic algebraic properties. It also enables the reconstruction of quantum probability theory via Gleason’s Theorem, which derives the Born rule from the geometry of Hilbert space. As a consequence, quantum probabilities violate Boole's classical "condition of possible experience'', today known as Bell-type inequalities. Beyond foundational insights, quantum logic offers conceptual pathways into emerging fields---notably quantum computation and quantum information---where non-classical reasoning becomes not merely permissible, but essential.

Workshop "Quantum Biology, Cognition, and Medicine" (10-11 June)

Organizers – Andrei Khrennikov, Lev Murokh, Gregory Scholes

Invited Speakers: C.Aspalter, F. Bagarello, F. Benninger, J. Bussemeyer (Indiana University,USA), Y. Dubi, M. Fuyama, Y. Gunji, A. Khrennikov, Y. Kim, W. Lawless, Z. Leonenko, L. Murokh, P. Naydenova, G. Scholes, O. Shor, S. Sozzo*, W. Sulis, J. Torres, I. Trofimova, N. Tsuchiya, L. Turin, M. Yamada, G. Vitiello

Summary: The quantum information revolution has spurred not only quantum technologies but also applications of quantum theory outside physics. This Workshop brings together researchers exploring quantum and quantum-like (quantum-inspired) approaches in various aspects of biology, chemistry, and medicine, including advanced diagnostics It also highlights quantum-like modeling in cognition, decision making, and social sciences, providing new frameworks to understand complex human and social behavior. By fostering interdisciplinary dialogue, the Workshop aims to advance both fundamental research and practical applications across physics, life sciences, and social sciences.

Workshop "Quantum-like concepts and formalisms applied in finance and economics: latest results”

Organizers – C. Gallus, E. Haven, P. Khrennikova

Summary: This satellite workshop will be dedicated to exhibiting the latest results in applications of the formalism of quantum mechanics to various areas of finance and economics. New theoretical developments will also be very welcome.”

Invited Speakers: C. Gallus, E. Haven, P. Khrennikova, S. Patra, A. Zarifian and W. Hicks.

Travel to and from Växjö

If you travel by train to Växjö you will reach Växjö Central located in the city centre. Travelling by train from Stockholm Central to Växjö Central takes roughly 3.5 hours. From Gothenburg to Växjö Central it takes roughly 3 hours.

If you instead choose to travel by air, you can choose to travel from Bromma Stockholm Airport to Växjö Småland Airport. You can also reach Växjö via flight to Copenhagen Airport/Kastrup and connecting direct train to Växjö Central (roughly 2.5 hours).

Travel in Växjö
For travel from Växjö Central or Växjö Småland Airport to Linnaeus University we recommend either bus or taxi.

By bus
When travelling by bus from Växjö Central to Linnaeus University, bus number 3, direction “Universitetet”, is the best option. However, there are also other bus routes that pass by one of the university’s bus stops or bus stops nearby, for instance, route number 1 and 5, which take you to Teleborg Centrum, some 8–10 minutes’ walk from the university’s campus.

Bus number 4 will take you from Växjö Småland Airport to Växjö Central where you can change to bus to get to Linnaeus University.

Bus tickets are purchased either on the bus with a debit card or you can download the travel app “Länstrafiken Kronoberg” and purchase your ticket in the app, which will give you a 10% discount on your ticket. You use your debit card to pay in the app.

By bicycle
In case you prefer a bicycle, many hotels can offer this. It takes roughly 20 minutes with a bicycle from the city centre to Linnaeus University’s campus.

By taxi
Most taxi companies start from Södra Bantorget at World Trade Center which means you can find available taxis here.

By car
There is a relative shortage of parking spaces on campus and all are subject to a charge. Parking spaces are marked on the map below.
