NeQxt is advancing trapped-ion quantum computing in Germany

NeQxt's quantum computers rely on precise manipulation of ions confined in a Paul trap, where individual ions act as qubits whose energy states are controlled by laser light and selectively addressed optical beams.

To enable these demanding experimental setups, SmarAct has supplied neQxt with a broad range of high-precision positioning systems. SmarAct engineered compact, ultra-high-vacuum compatible nanopositioning modules tailored to neQxt’s spatial and mechanical requirements. These systems achieve sub-micrometer accuracy and exceptional mechanical stability, ensuring that laser beams can be aligned with the precision required to address single ions within the trap.

Alongside these custom-developed solutions, standard SmarAct positioning components are integrated throughout neQxt’s optical infrastructure to guide, align, and stabilize the laser beams essential for qubit initialization, manipulation, and readout.

A central component of this collaboration is SmarAct’s XYZ-STT system, which leverages advanced nanopositioning technology to enable positioning directly inside ion traps and to accelerate real-world quantum research. Integrated into neQxt’s trapped-ion platforms, these systems form a critical foundation for scalable, high-fidelity quantum operations across both projects.
