ZuriQ, an ETH Zürich spin-out, has secured $25.5 million in seed funding to scale its groundbreaking two-dimensional trapped-ion quantum architecture. This round, led by Quantonation with participation from Forward.one, Extantia, Firgun Ventures, and previous investors, follows a $4.2 million pre-seed round in 2025.
The Swiss quantum computing company aims to significantly increase the number of qubits on a single chip, leveraging its novel approach to trapped-ion quantum processors. This investment underscores continued interest in quantum computing investment rounds, even as the field matures.
A New Dimension in Quantum Computing
Unlike conventional trapped-ion systems that rely on one-dimensional chains and complex junctions, ZuriQ’s design is natively two-dimensional. It employs Penning micro-traps, utilizing a static magnetic field instead of the rapidly oscillating fields found in legacy architectures. This allows ions to move freely in any direction, unconstrained by junctions.
Professor Jonathan Home of ETH Zürich, a scientific adviser to ZuriQ, emphasized the geometric advantage. "Hold ions in two dimensions, and it grows with the area of the chip, on a standard chip, that is the difference between tens of ions and many thousands." This flexibility in ion movement also enables more versatile connectivity, crucial for complex quantum applications.
ZuriQ has already proven its concept with a working demonstrator: a 3x3 array of nine individually controlled ions. Developed in just 18 months, this represents the largest two-dimensional array of its kind to date. The chips, fabricated in collaboration with Infineon, confirm the architecture's compatibility with established industry processes.
