The round builds on the company’s $4.2m pre-seed round in 2025 and will be used to scale and grow the organisation’s quantum ambitions.

ZuriQ, a quantum computing company based out of Switzerland, has announced a seed funding round of $25.5m.

The round follows a successful $4.2m pre-seed round in 2025 and this year was led by Quantonation, with participation from Forward.one, Extantia, Firgun Ventures and additional previous round investors.

ZuriQ is a spin out of ETH Zürich and intends to use the funds to scale its trapped-ion quantum processors and expand its team alongside research and development efforts as it works to significantly increase the number of qubits its architecture can support.

According to the organisation, the majority of trapped-ion quantum computers are based on a decades old design in which ions are held in one-dimensional chains stitched together into larger grids using complex junction structures.
