Ukraine Quantum Computing Companies 2026: Complete Vendor Guide

The question of the leading ukraine quantum computing companies in 2026 has an unusual answer. Ukraine has one commercial quantum-software company with clear Ukrainian roots, Haiqu, which is headquartered in the United States and runs a distributed team that includes Ukrainian engineers, plus a deep academic foundation across the Bogolyubov Institute for Theoretical Physics (BITP) in Kyiv, the B. Verkin Institute for Low Temperature Physics and Engineering (ILTPE) in Kharkiv, the Igor Sikorsky Kyiv Polytechnic Institute (KPI), the Taras Shevchenko National University of Kyiv, and the Ivan Franko National University of Lviv. This guide profiles that single company alongside the five academic anchors that train the country’s quantum-physics talent. Context note: The Ukrainian quantum-research community has been heavily affected by the full-scale invasion that began in 2022. Many researchers have relocated temporarily to EU and US partner institutions, so this guide describes the footprint as it operates inside Ukraine and across the wider Ukrainian technical diaspora in 2026. Ukraine produces more per-capita quantum-physics and quantum-software talent than its small company count suggests. That draws on a long academic tradition in low-temperature physics at Kharkiv, mathematical and theoretical physics at Kyiv, and condensed-matter physics at Lviv. The clearest commercial outcome of…
