Terra Quantum is a Quantum Software & Applications company founded in 2019 and based in St. Gallen, Switzerland. It has raised $75M in total funding, most recently a Series A in 2022.

Terra Quantum joins the QuEra Quantum Alliance to connect its TQ42 quantum software with QuEra's neutral-atom hardware.
Quantum AI development platform launched in closed beta April 2025, combining a no-code visual interface (QAI Hub) with a code-level Python SDK (Qode Engine) for building hybrid quantum-classical machine learning models. QAI Hub includes TQ Copilot, an AI assistant that tunes quantum layers and adjusts hyperparameters from natural language input. Target applications include industrial forecasting, optimization, anomaly detection, and options pricing; backed by partnerships with HSBC, Aramco, and Siemens.
Library of hybrid quantum-classical optimization algorithms accessible via the TQ42 platform and Qode Engine SDK. Implements quantum-inspired and near-term variational algorithms for logistics scheduling, supply chain optimization, and combinatorial problems. Deployed in pilot projects with Volkswagen and large enterprise partners; Terra Quantum claims breakthrough quantum optimization advantages on near-term NISQ hardware using tensor network and variational methods.
