If you’ve ever heard that the universe tends toward chaos, you’ve brushed up against the idea of entropy. It’s a concept initially describing how heat spreads and energy becomes less useful—but over time, scientists have discovered entropy’s connection to much more than just thermodynamics. It links information, randomness, and even the strange world of quantum computing.
That connection is exactly what researchers, scientists, and curious minds will be exploring at Entropy 2026, the third International Conference on Entropy, happening July 1–3, 2026, in Barcelona, Spain. Themed “Exploring Complexity and Information in Science,” the event brings together over 200 participants to discuss topics ranging from information theory to quantum computing and complex systems. Organized by MDPI’s Entropy journal, the conference follows successful editions in 2018 and 2021 and continues to serve as a meeting point for those fascinated by the many faces of entropy.
Among the highlights is Session 3: Quantum Information and Quantum Computing, which dives into how classical ideas like entropy and information are reimagined in the quantum domain. Led by distinguished chairs Prof. Miguel Rubi (University of Barcelona) and Prof. Kevin H. Knuth (University at Albany), the session will feature keynote speakers Prof. Eli Barkai and Prof. Ariel Caticha, both pioneers in connecting thermodynamics and quantum behavior. Abstracts are being accepted through April 1, 2026 (extended), with early-bird registration open until April 22.
Entropy links heat, information, and quantum computers in profound ways that bridge thermodynamics, information theory, and quantum computing. At Entropy 2026, researchers will explore these connections in depth.
The heart of this conference—and of modern quantum study—rests on how entropy has evolved. Recent research by Thomas Scheidsteger and Robin Haunschild traces this journey: how a term once linked only to heat and energy became a bridge between quantum physics and information science. Using digital tools to analyze thousands of scientific papers, their work maps the “intellectual lineage” of quantum information theory. It shows how entropy underpins everything from entanglement—that famously spooky quantum connection—to the thermodynamics of quantum computation, which explores how information and energy intertwine in quantum machines.
These turning points, especially in the early 2000s, wove entropy into a shared language across disciplines, describing how order, uncertainty, and complexity coexist at every level of reality. It’s this very intersection—the space between physics, information, and computation—that continues to captivate the scientific imagination.
Understanding entropy’s journey is like following a single thread weaving through centuries of discovery. It’s tying together how we think about heat, information, and now quantum technology. The story is far from over; in fact, it’s accelerating.
That’s why Entropy 2026 is more than just a conference—it’s a chance to witness the frontlines of this unfolding story. Whether you’re a researcher, student, or simply someone curious about how the universe keeps track of its own complexity, the conference offers an inspiring window into the science shaping tomorrow.
