ABOUT THE CONFERENCE
Analog Quantum Computation: From Annealing to Simulation.
Quantum annealing is a method of quantum computation for solving combinatorial optimisation problems operating in continuous time, a feature that is shared with various methods of analog quantum simulation. The International Network on Quantum Annealing (INQA) 2025 conference aims to bring together leading experts in analog quantum computation and simulation to share and discuss their latest results. Theoretical, numerical and experimental works are welcome, as well as contributions within the theme from related fields.This year’s conference of INQA will be held in Barcelona, Spain, from November 2 – 5, 2025. This is the 4th instalment of this conference series, which previously took place in London (2022), Innsbruck (2023) and Tokyo (2024).
