Qendra AG

Qendra delivers next-generation control systems for quantum computing experiments — uniting precision, synchronization, and scalability across every signal in your lab. Qendra AG is a deep-tech spin-off from ETH Zurich. We build the classical control system for quantum computers based on trapped ions and neutral atoms — the hardware and software that turns a quantum algorithm into precisely timed laser pulses, electrode voltages and other control signals. The system originates from more than ten years of development in the Trapped Ion Quantum Information group at ETH Zurich. Earlier generations have been used in landmark experiments at ETH Zurich and the University of Innsbruck. Our product suite consists of Qendra Pulse (RF generation and laser control), Qendra Vision (low-latency camera readout), Qendra Volt (voltage generation) and Qendra Symphony (orchestration software). We are backed by QAI Ventures, Constructor Capital and others. We have several pilot installations in academia and at a quantum computing company based in Zurich.
